Dual plasmonic Au and TiN cocatalysts to boost photocatalytic hydrogen evolution

Plasmon-Enhanced Photocatalysis Based on Plasmonic Nanoparticles for Energy and Environmental Solutions: A Review

“…(h) The possible pathways for the transfer of electrons from g-C 3 N 4 to Au cocatalyst or to TiN cocatalyst to participate in H 2 production, before and after contact. Reproduced with permission from ref . Copyright 2022 Elsevier.…”

“…Qureshi and his colleagues made a dual plasmonic cocatalyst that included Au and TiNNPs over g-C 3 N 4 nanotube to improve photocatalytic hydrogen production. Three composites of TiN/g-C 3 N 4 were prepared with different loadings of TiN (20 mg TiN noticed as TCN), and subsequently, three samples of Au/TiN/g-C 3 N 4 composite with three different Au loadings (1.5% Au loading was named as ATCN) were produced as well as the Au/g-C 3 N 4 sample being named as ACN.…”

The order of loading affects photocatalytic nitrogen fixation activity of the ternary composites of PdO/Au–TiO2

“…[42][43][44][45] In addition, according to the reports, Au NPs can contribute to the reduction of electron-hole recombination by charge separation, which further increases the photocatalytic activity under the condition of simulated solar light. [46][47][48][49] For example, Qureshi et al constructed multiple interfaces and dual junctions of Au/g-C 3 N 4 Schottky-junction and TiN/g-C 3 N 4 ohmicjunction, 50 and these procedures contributed to promote the separation of charge carriers and improve the performance of photocatalytic hydrogen production. Furthermore, researchers have repeatedly stressed that loaded plasmonic cocatalysts, e.g., Au and Ag NPs, can enhance the light absorption capacity.…”

Noble metal-free ternary cobalt–nickel phosphides for enhanced photocatalytic dye-sensitized hydrogen evolution and catalytic mechanism investigation

“…24 In a dye-sensitized photocatalytic hydrogen evolution reaction (HER) system, the presence of an efficient HER cocatalyst is essential to minimize overpotential, facilitate the separation of photogenerated electrons and holes, and enhance the overall efficiency of the photocatalytic HER process. [25][26][27] Noble metals, including platinum (Pt), 28 ruthenium (Ru), 29 rhodium (Rh), 30 gold (Au) 31 and palladium (Pd), 32 have demonstrated remarkable catalytic properties as cocatalysts. 33 However, their widespread industrial implementation is hindered by cost considerations and challenges associated with post-reaction recovery.…”
