Among these materials, composites such as boron (B)-doped titanium dioxide, B-doped graphene, and B-doped carbon nitride are distinguished by their exceptional performance in various photocatalytic reactions. These enhancements are primarily attributed to the unique electronic structure of B, its small size and electron deficiency facilitate improved carrier detached and diminished regrouping rates, thereby expanding the spectrum of light absorption. Despite considerable advancements, the specific role of B within photocatalytic systems remains ambiguously defined, with ongoing research yet to conclusively determine whether B functions primarily as a catalyst (a key) or merely as a supportive enhancer (an auxiliary). Addressing this gap, this review adopts a novel analytical perspective, investigating the electron-deficient nature of B to elucidate it’s in photocatalysis distinct advantages, potential regimes, and practical applications.

However, the quest for an optimal photocatalyst suitable for industrial-scale applications remains a strenuous challenge. The journey to identify the optimal photocatalyst for the water splitting reaction has been extensive and remains ongoing. While the search started with the use of inorganic semiconductors based on metal oxides, such as TiO₂, many new and promising materials, such as Metal-Organic Frameworks (MOFs), have started to attract the attention of the scientific community. However, in order to be able to improve the efficiency of any photocatalyst, it is important to first understand how the reaction is taking place, in other words, it results imperative to understand the reaction mechanism. The aim of the following review is to study and analyze different experimental techniques that can be used for the elucidation of the reaction mechanism covering both water splitting’s half reactions: hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and overall water splitting (OWS). This work starts with the fundamentals of photocatalytic OWS under solar irradiation, followed by the systematical evaluation of distinct MOF-based photocatalysts, classifying them based on the specific metal ion in their composition which facilitates standardized comparisons. The mechanistic investigation of photocatalysts is then detailed, employing various spectroscopic techniques. While a higher focus has been given to the analysis of the mechanistic study on MOFs, other important photocatalysts counterparts are also explored, as they have helped to cement the bases in which new materials can be studied. Furthermore, by comparing results obtained for conventional photocatalysts (e.g., metal oxide semiconductors) with those obtained for newer materials like MOFs, we attempt to show the great amount of information that can be extracted for the elucidation of reaction mechanisms. This systematic approach aims to help better investigate the mechanistic study and designing the next generation of photocatalysts for HER, OER, and OWS.</div></div>","PeriodicalId":376,"journal":{"name":"Journal of Photochemistry and Photobiology C: Photochemistry Reviews","volume":"60 ","pages":"Article 100680"},"PeriodicalIF":12.8,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142663663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
