Some widely employed industrial processes are major contributors to CO₂ emissions. A prime example is ammonia production, which represents a high energy consumption, utilizes natural gas, and generates hundreds of millions of tons of CO₂ annually. Proper waste treatment, alternatives to fossil fuels, and chemical compound production processes are crucial to address these issues. In this regard, (photo)electrochemical techniques such as electrocatalysis (EC) and photoelectrocatalysis (PEC) can aid in the clean and cost-effective treatment of wastewater while also generating new fuels and commercially valuable chemical compounds. Reduction reactions can be specifically applied to (i) CO₂ molecules, producing fuels; (ii) N₂ molecules, generating NH₃; and (iii) H + species, producing H₂. Oxidation reactions can be employed for organic and inorganic molecules present in real effluents, aiming to treat contaminated water. Electrocatalytic Brazilian research groups have been contributing not only to those redox reaction investigations but also to the synthesis of electrocatalysts for both reactions, making them more cost-effective, specific, and efficient, opening new perspectives in the generation of environmentally friendly chemical compounds with added value, clean energy conversion (non-petroleum energy), and minimizing the economic impact of environmental wastewater treatments. Thus, this work offers for the first time insights into the strengths, challenges, and prospects of electrochemical applications in the fields of energy and environmental remediation in Brazil, highlighting the country’s significance as a source of scientific knowledge on a global scale.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 3","pages":"795 - 835"},"PeriodicalIF":2.6,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142268146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such a way, carbon nitride (C₃N₄) has been studied as an electron acceptor. With simple synthesis and easy tailoring properties, this material becomes a promising candidate in organic photovoltaic cells. Thus, the objective was to evaluate the photocurrent as a function of exciton properties. Then, P3HT was obtained by redox polymerization and C₃N₄ by urea pyrolysis. Photoelectrochemical and spectroscopic measurements were performed to characterize the electrodes. In addition, theoretical calculations were carried out using TD-DFT. It was observed that a photocurrent 3-fold increased in relation to the pure P3HT film (from 12.1 up to 33.2 µA cm^-2), attributed to the increase in the hole-electron separation efficiency, with an increase in their lifetime (from 0.18 to 0.42 ms). The electron transport was also boosted (an increase of 2.1<span>(times )</span>10^-3 cm² V^-1 s^-1). The theoretical calculations suggest that the structural modification of C₃N₄ affects the photocurrent due to the charge delocalization induced by the torsion of the triazine units. Besides, the photocurrent values achieved in this work were not expressive; the results pointed out that the association P3HT+C₃N₄ is promissory. The further optimization of these systems by heat treatment, type of solvent, and deposition method could lead to better results.
