PEC is an emerging technique that holds great promise for addressing two critical challenges simultaneously, namely, the degradation of industrial wastewater pollutants and the generation of clean energy in the form of hydrogen gas. In recent years, many studies have explored the use of photoanodes to harness solar energy for wastewater treatment. These photoanodes facilitate the breakdown of contaminants, while the cathode concurrently produces green hydrogen. The PEC enables the production of both clean water and hydrogen gas from industrial wastewater. This dual benefit makes it an attractive avenue for sustainable industrial wastewater treatment and clean energy generation. The PEC process capitalizes on the constructive interaction between electrochemical reactions and photocatalysis. Solar energy is efficiently converted into electron-hole pairs, which play a pivotal role in water-splitting reactions occurring at the electrode surfaces. Achieving the best performance involves scrutiny of various parameters, including catalyst loading, pH, light intensity, and electrolyte composition. The photoelectrocatalytic system shows commendable stability and durability during extended operation, reinforcing its practical applicability. This review provides a comprehensive overview of the PEC process, catalyst materials, optimization strategies, and driving efficiency. Considering the potential benefits and costs on a larger scale underscores the significance of photoelectrocatalytic hydrogen production in addressing environmental concerns and energy-related issues concurrently. Therefore, PEC is a promising pathway toward sustainable water treatment and clean energy, bridging the gap between environmental stewardship and technological advancement.</p></div>","PeriodicalId":100892,"journal":{"name":"Materials Today Catalysis","volume":"5 ","pages":"Article 100052"},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949754X24000140/pdfft?md5=859263673233ef9528b2bfb6800c0db1&pid=1-s2.0-S2949754X24000140-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141089827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breaking away from traditional transition metal complexes, the focus is on designing and selecting efficient organic catalysts. In this pursuit, a diazo-based organic bulky ligand emerges as a promising candidate, offering a solution that is both sustainable and renewable. The key feature of this ligand is its low-lying π* (LUMO), enabling it to readily accept an electron in an electrochemical environment when a potential is applied. The synthesized Diazo-based ligands have been meticulously characterized using various techniques, including ¹H NMR, ¹³C NMR, UV-Vis, and IR spectroscopy. This diazo-based ligand serves as an electrocatalyst, undergoing reduction to a triplet diradical that acts as a nucleophile. In an aqueous medium, it forms an adduct with CO₂, leading to the generation of a formyl radical. This radical further couples to produce acetic acid and acetone with efficiencies of 19.6% and 24.2%, respectively, at pH 5.5. To provide a deeper understanding, we present a proposed mechanism pathway supported by <em>in-situ</em> UV-Vis spectroscopy and a comprehensive Density Functional Theory (DFT) study.

Developing clean and sustainable hydrogen (H₂) energy and corresponding storage and conversion devices have attracted increasing attention. The utilization of H₂ energy highly depends on the fuel cell (FC). However, the slow kinetics of oxygen reduction reaction (ORR) on the cathode of FC cannot be improved without efficient catalysts. Currently, precious metal platinum (Pt) and its alloys are commonly used catalysts for ORR process. However, the scarcity and high cost of Pt hinder their large-scale practical application. To replace typical Pt-based catalysts, non-precious metal electrocatalysts have been investigated for ORR. Inspired by the catalytic ORR active center Fe porphyrin of cytochrome <em>c</em> oxidase in nature, metalloporphyrin-based frameworks and their derivatives have become promising electrocatalysts due to their abundant conjugated electronic structure, tunable functional groups, and large specific surface area. First, this review briefly introduces porphyrins and catalytic ORR mechanisms. Second, recent progress on porphyrin-based ORR catalysts including porphyrin-based frameworks, framework@substrate composites, and framework-based derivatives was summarized. Porphyrin-based frameworks mainly include metal-organic frameworks (MOFs), covalent organic frameworks (COFs), hydrogen-bonded organic frameworks (HOFs), and polymers constructed with porphyrin building blocks. Porphyrin-based framework@substrate composites were usually assembled and constructed to improve the electron transfer rate of frameworks. To further improve the conductivity, framework-based derivatives, usually named metal, nitrogen-doped carbon (M-N-C) materials, were synthesized through pyrolyzing frameworks at high temperatures. Finally, research challenges and directions of porphyrin-based electrocatalysts for ORR were discussed. This review is meaningful and enlightening for designing and developing other porphyrin-based electrocatalysts for ORR.</p></div>","PeriodicalId":100892,"journal":{"name":"Materials Today Catalysis","volume":"4 ","pages":"Article 100044"},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949754X24000061/pdfft?md5=0f859c2fce51d0112a50a98024bfc9ed&pid=1-s2.0-S2949754X24000061-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139936342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
