Every year around this time, we like to look back at the previous year, share a list of our favorite papers and look ahead to where things are headed next. 2023 was a big year for us at HepatoChem. We moved into a new lab space, shipped Lucent360&#x2122; photoreactors around the world and expanded our product line of LEDs. Our PhotoRedox boxes, by our unofficial tally, were cited more than 70+ times in the literature in 2023 alone and topping 200+ since launch. We took part in a great research project using the Lucent360&#x2122; <a href=\"https:\/\/pubs.acs.org\/doi\/10.1021\/acs.oprd.2c00379\">published this year<\/a>. Also, we added many new posts to <a href=\"https:\/\/hepatochem.com\/fr\/blog\/\">our blog<\/a> and newsletter on fun and obscure topics such as <a href=\"https:\/\/hepatochem.com\/fenton-boat-photocatalysis-an-adventure-with-iron-and-wood\/\">Fenton Boats<\/a>, <a href=\"https:\/\/hepatochem.com\/nucleic-acid-chemistry-and-sequencing-epigenetic-modifications\/\">DNA sequencing<\/a> and the <a href=\"https:\/\/hepatochem.com\/searching-for-the-origin-of-life-with-photoredox-organocatalysis\/\">Origin of Life<\/a>. What does 2024 have in store for us? Expect a new PhotoReactor, more LED options, more publications using our products, and more blog posts and newsletters.<\/p>\n<p>As for our favorite papers from 2023? Some like to make their year-end lists sometime around early December fully forgetting an entire month of the year. We would like to be fashionably late and send this out some time in the next year. If you see this before the end of January, we consider it a success. This will be our 4th list \u00ab\u00a0highlighting\u00a0\u00bb the photochemistry literature (previous lists can be found here, <a href=\"https:\/\/hepatochem.com\/the-20-must-read-photochemistry-papers-from-2020\/\">2020<\/a>, <a href=\"https:\/\/hepatochem.com\/the-21-must-read-photochemistry-papers-of-2021\/\">2021<\/a>, and <a href=\"https:\/\/hepatochem.com\/photochemistry-2022\/\">2022<\/a>). We would specifically like to highlight \u00ab\u00a0highlighting\u00a0\u00bb as reviewing the sum of photochemistry literature from 2023 is virtually impossible. It&rsquo;s a safe bet to say that more photochemistry papers were published last year than any previous year, and we don&rsquo;t have time for that. As we described in the past, these are our favorite 23 photocatalysis papers from 2023. This is not a list that attempts to find the best, or most viewed, or most famous 23 papers from the year. Or rank them in any way. This is not generated by Chat GPT, these are simply our handpicked favorites. As always, if your paper is Open Access, we&rsquo;re more likely to like it as well. We are certain that we have missed many great papers from the past year and hope that you, the reader, can help us out with any that we missed. Instead, this is just a list of the 23 papers that we thought were the best, funniest, oddest, most interesting, or downright unexpected. Since most people are just skipping past this past this description anyway or simply hitting \u00ab\u00a0control+F\u00a0\u00bb for their name anyway, we&rsquo;ll just get to the list.<\/p>\n<p>So, here we go. Keep reading for our favorite papers from 2023 and then send us your favorites on twitter (<a href=\"https:\/\/twitter.com\/evoluchem?lang=en\">@EvoluChem<\/a>) or at <a href=\"mailto:info@hepatochem.com\">info@hepatochem.<\/a><\/p>\n<h3>Paper 1:<br \/>Carbon-to-nitrogen single-atom transmutation of azaarenes<\/h3>\n<p><strong>Authors<\/strong>: Jisoo Woo, Colin Stein, Alec H.

We recently added UV capabilities to the Lucent360 extending the instrument&rsquo;s range from 254 nm to 808 nm. As a result, we&rsquo;ve started looking more into reactions that can be run at more \u00ab\u00a0traditional\u00a0\u00bb photochemistry wavelengths in the UV but also have visible light companions. That reading led us here, a great example of upconversion of blue light into the UV region.<\/p>\n<p>&nbsp;<\/p>\n<h3>Paper 16:<br \/>Sustainable Wood-Based Iron Photocatalyst for Multiple Uses with Sunlight: Water Treatment and Radical Photopolymerization<\/h3>\n<p><strong>(Open Access)<\/strong><br \/><strong>Authors<\/strong>: Xiaolin Guo, Xinpeng Zhao, Xiongfei Luo, Yulian Pang, Bing Tian, Shouxin Liu, Shujun Li, Jian Li, Bernd Strehmel, and Zhijun Chen<br \/><strong>Ref<\/strong>: Angew.

This is truly impressive. The authors made a sustainable, useful photocatalyst out of three of the cheapest things available, wood, iron and sunlight. There are many big picture problems that can be aided with photocatalysis. But there are certain problems where the task is so vast like water treatment that the solution needs to be less than cheap to have any chance of making a realistic improvement. Few things are cheaper than wood, iron and sunlight.\r\nA sustainable catalyst should be recyclable and derived from sustainable materials. Iron oxides are well known materials for heterogenous photocatalysis, although to be successful often need to be modified with photosensitizers or frameworks derived from fossil fuels. Wood is a natural replacement. Natural wood is fluorescent and phosphorescent due to lignin, cellulose and hemicellulose. For this work, modified wood doped with iron oxide acts as a photosensitizer for photocatalytic cycles, mainly photo-Fenton reactions and photopolymerizations.\r\nThe catalyst is prepared by treating wood with BBr3 to remove the methyl groups from the lignin and creating free phenols. The D-Wood was then treated with FeCl3 followed by NaOH. This process was repeated 5 times, to give Fe3O4-D-Wood containing 19% weight percent Fe3O4 (Figure 1). This material was then extensively characterized, to an extent that we can\u2019t do justice in this short piece. An alphabet soup of techniques characterized the structure including computer tomography (CT), X-ray diffraction (XRD), FT-IR, XPS, Electrochemical impedance spectroscopy (EIS), Cyclic voltammetry (CV) and visible absorption spectroscopy. All the data support a new material capable of proton electron transfer (PET) reactions consisting of a wood chamber filled with Fe3O4 particles coordinated by free phenols. The material has red-shifted absorbance observed after treating the D-Wood with iron confirming ligand to metal interactions. Fluorescence (1.64 ns) and Phosphorescence decay (0.38 ms) of D-Wood were confirmed demonstrating singlet and triplet states, while both were both suppressed upon addition iron, suggesting the new catalyst has non-emissive excited states. Similar characterization of Fe3O4-Wood (no demethylation) demonstrates the importance of the free phenols to catalytic activity.\r\nFigure 1: Fe3O4-D-Wood photocatalyst\r\n\r\n\u00a0\r\n\r\nThe authors next set up an experiment to test their new catalyst for the Photo-Fenton degradation of rhodamine B (RhB) with H2O2. In the dark, Fe3O4, Fe3O4-Wood, a mixture of separate iron and D-wood powders as a control and Fe3O4-D-Wood powder showed slow degradation (0.002-0.007 min-1). Turn on the artificial sunlight source and Fe3O4-D-Wood increases to 0.13 min-1 with 99% degradation of rhodamine by UV\/Vis spectra while no increased rate was observed for the other species. Controls confirm that reaction is proceeding via the wood catalyst and not iron leaching into solution. Further experiments varying pH, testing stability of the catalyst and recycling the catalyst were all performed with a simulated pollution sample for the degradation of 8 common pollutants. After 40 minutes of irradiation, 51% of organic contaminants were removed.\r\nAs one does when making photocatalysts, the authors also tested materials made of different sources of natural wood including Beech wood, Pine wood, and Red Walnut with small variations in efficacy. Why did we feel the need to add this detail? Because for some reason the idea that different species of trees have different photochemical properties based on the structure of their lignin is fascinating to us simple chemists.\r\nSo, we promised you a Fenton Boat? Why a boat? Because small powder chunks of the wood catalyst sink to the bottom of a polluted body of water, limiting interaction with sunlight while a boat floats. The wooden boat was treated with BBr3\/Fe conditions to generate a Fenton Boat that floats. The Fenton Boat absorbs polluted water via capillary action into the wood and concentrates in the pores and degrades via the Fenton reaction initiated by the photocatalyst. In a test experiment using artificial sunlight nearly 100% of RhB degradation was observed and in polluted water organic contaminants decreased by ~66%. The boat can be reused and more importantly recovered and moved by magnets. Just an incredible idea. There is far more work left to discuss including their experiments looking at radical traps, the kinetics, and discussion of mechanism, but we know everyone just wants to see the boat. For the purposes of scale, we\u2019ll note that the boat fits inside a 1 L beaker. To clean up a larger body of water, we\u2019re going to need a bigger boat.\r\n\r\nFor a video of the boat in action click through
