Energy-band-controlled ZnxCd1−xIn2S4 solid solution coupled with g-C3N4 nanosheets as 2D/2D heterostructure toward efficient photocatalytic H2 evolution

Emerging Concepts in Carbon Nitride Organic Photocatalysis

“…For example, Yu and Zhang developed a 0D/2D S-Scheme heterojunction material composed of CeO 2 quantum dots and CN for photocatalytic deactivation of bacteria. [63] Zou and Shi designed a complex Z nx Cd 1-x In 2 S 4 solid solution coupled with CN nanosheets as a 2D/2D heterostructure, [64] a material possessing heterojunction between CdS, WO 3 and CN, [65] and ultrathin CN nanosheets modified with Cu 2 MoS 4 for H 2 liberation. [66] Overall, a comprehensive summary on CNs synthesis, characterization, properties, and environmental applications are available in reviews.…”

CdS/ZnS/ZnO ternary heterostructure nanofibers fabricated by electrospinning for excellent photocatalytic hydrogen evolution without co-catalyst

“…Binary semiconductor HSs with three different configurations: type-I [35], type-II [36,37], and Z-scheme [38] have been reported. In recent years, ternary HSs consisting of three semiconductors have attracted considerable attention.…”

Cu3P and Ni2P co‐modified g‐C3N4 nanosheet with excellent photocatalytic H2 evolution activities

“…[7][8][9] Currently, many efforts have been devoted to exploiting semiconductor-based photocatalysts, such as cadmium sulfide (CdS), [10][11][12] titanium dioxide (TiO 2 ) , 13,14 bimetallic sulfides, 15,16 bimetallic phosphides 17 and graphite-like phase carbon nitride (g-C 3 N 4 ). 4,[18][19][20][21] g-C 3 N 4 is a rising star amongst these because of its appropriate bandgap, lowcost, nontoxic and earth-abundant nature, facile preparation and high thermal/ chemical stability. [22][23][24][25][26][27] Nevertheless, the photocatalytic activity of pristine g-C 3 N 4 is still limited by its inherently lower carrier transfer efficiency and rapid recombination of photo-induced e − -h +.…”

“…Among the alternative energy sources, hydrogen (H 2 ) is thought to be an ideal substitute to alleviate energy and environmental problems because of its high energy density, zero pollution, as well as sustainable and regenerative features 7–9 . Currently, many efforts have been devoted to exploiting semiconductor‐based photocatalysts, such as cadmium sulfide (CdS), 10–12 titanium dioxide (TiO 2 ) , 13,14 bimetallic sulfides, 15,16 bimetallic phosphides 17 and graphite‐like phase carbon nitride (g‐C 3 N 4 ) 4,18–21 . g‐C 3 N 4 is a rising star amongst these because of its appropriate bandgap, lowcost, nontoxic and earth‐abundant nature, facile preparation and high thermal/chemical stability 22–27 .…”
