Powerful combination of 2D g-C3N4 and 2D nanomaterials for photocatalysis: Recent advances

Electrostatic self‐assembly of 2D‐2D CoP/ZnIn2S4 nanosheets for efficient photocatalytic hydrogen evolution

“…Up to now, multitudinous semiconductors have been explored as photocatalysts for solar hydrogen generation, however, most of them have low photocatalytic performance because of the weak light absorption and inefficient photointroduced charge carriers separation/transport, which greatly hinder their practical and large-scale applications. [5][6][7][8] Two-dimensional (2D) photocatalysts have been proven to be promising to solve the above-mentioned problems due to their abundant surface-active sites, huge specific surface area, and excellent charge carrier separation. 4,6,[9][10][11][12][13][14] Very recently, ZnIn 2 S 4 (ZIS), especially single/few-layered 2D ZIS has been considered as an outstanding photocatalyst for hydrogen generation, mainly due to its good chemical stability, suitable band gap, and excellent photocatalytic performance.…”

[10][11][12] Nonetheless, as most of semiconductor-based photocatalysts, individual ZIS still reveals unsatisfactory photocatalytic activity due to its rapid electron-hole recombination and large hydrogen evolution overpotential, resulting from lack of driving force for separating photogenerated charge carriers.…”

The Influence of Photoactive Heterostructures on the Photocatalytic Removal of Dyes and Pharmaceutical Active Compounds: A Mini-Review

“…The increase of PhACs concentration raises essential issues to traditional wastewater treatment [ 85 , 86 , 87 ] and requires the involvement of novel processes such as photocatalysis [ 88 , 89 , 90 ]. The literature mentions a high number of PhACs investigated in AOP experiments, between the most representative are: TC, CIP, TCS, CBZ, SA, IBS and SMZ.…”

Two‐photon Absorption in a Defect‐engineered Carbon Nitride Polymer Drives Red‐light Photocatalysis

“…[14] To date, numerous approaches have been developed to improve the light-harvesting capability of PCN. [15][16][17][18][19] For example, Liu et al [20] found that amorphous PCN displayed excellent light-harvesting ability and the light absorption edge was up to 682 nm. Zhang et al [21] provided an effective strategy to narrow the band gap of PCN through cocondensation of urea and oxamide followed by post-calcination in molten salt.…”
