Band-Edge Electronic Structure on Photo(electro)catalytic Performance of ABO2 (A = Cu, Ag; B = Al, Ga, In): Elucidating the Role of Valence Electron States

“…The first involves the modification of traditional photocatalytic materials using techniques such as heteroatomic doping, 4 heterostructure construction, 5 solid solution design, 6 noble metal loading, 7 and dye sensitization. 8 The second direction involves the development of novel photocatalytic materials such as g-C 3 N 4 and Bi 2 CrO 6 . 9,10 The third avenue explores the integration of special physical effects, including local surface plasmon resonance, intermediate bands, and multiferroicity.…”

“…Currently, three primary avenues are being explored for the development of such efficient photo­(electro)­catalytic materials. The first involves the modification of traditional photocatalytic materials using techniques such as heteroatomic doping, heterostructure construction, solid solution design, noble metal loading, and dye sensitization . The second direction involves the development of novel photocatalytic materials such as g-C 3 N 4 and Bi 2 CrO 6 . , The third avenue explores the integration of special physical effects, including local surface plasmon resonance, intermediate bands, and multiferroicity. , Regardless of the chosen development strategy, a profound understanding of the electronic structure of photo­(electro)­catalytic materials, particularly the band edges (i.e., the top of the valence band and the bottom of the conduction band), is imperative.…”

Heterogeneous visible-light promoted dehydrogenative [4 + 2] annulation of benzothioamides and alkynes under aerobic conditions

“…Among heterogeneous photocatalysts, graphitic carbon nitride (g-C 3 N 4 ) is a promising one possessing a medium band gap (2.7 eV) and favorable positions of the valence band (1.2 V vs. SCE) and the conduction band (−1.5 V vs. SCE), which allows for oxidation and reduction of many substrates in a controlled manner. 7 g-C 3 N 4 has exceptionally high chemical stability (up to 600 °C in air) and displays excellent tolerance to both strongly basic and acidic conditions, as well as reactive nucleophiles, electrophiles, and radicals. 8 The metal-free nature of g-C 3 N 4 makes it more appealing than transition metal-based homogeneous photoredox catalysts in view of strict limits on the level of trace transition metals in pharmaceuticals.…”

Cu2MoS4/CdS Nanosheet-Modified Nanowire Nanocomposites for Significantly Improved Visible Light-Driven Photocatalytic H2 Evolution Activity

“…1−3 In particular, the study of visible-light-driven semiconductor photocatalysts is a hot research topic in this area. In recent years, various photocatalysts with efficient H 2 evolution performance have been reported, such as metal oxides, 4,5 sulfides, 6,7 nitrides, 8,9 metal−organic frameworks, 10,11 perovskite materials, 12,13 etc. Regrettably, most of them suffer from low visible-light absorption capacity, leading to poor photocatalytic H 2 production performance.…”
