Plasmonic Cocatalyst with Electric and Thermal Stimuli Boots Solar Hydrogen Evolution

Abstract

Solar Hydrogen Evolution In article number http://doi.wiley.com/10.1002/solr.202000094, Xiaoyong Xu, Jingguo Hu, Yong Zhou, and co‐workers introduce plasmon‐mediated electric and thermal stimuli into photocatalysis. Nickel nanoparticles function as plasmonic cocatalysts anchored on graphitic carbon nitride nanosheets to expand solar utilization over the NIR region for photocatalytic hydrogen evolution. Plasmon amplifies electric fields, and thermal relaxation generates heat, leading to positive effects on light absorption, electron transfer, and surface catalysis for solar‐to‐hydrogen conversion.

Activation Strategy of WS2 as an Efficient Photocatalytic Hydrogen Evolution Cocatalyst through Co2+ Doping to Adjust the Highly Exposed Active (100) Facet

“…As shown in Figure a, compared with the original CZS, the results show that Cd, Zn, S, W, and C elements existed in this binary system, C was the background signals of C 1s at 284.8 eV, which belong to sp 2 carbon. [ 35 ] All the peak positions are consistent with the original, only the peak intensity has decreased, which may be caused by the composite masking of surface elements. Moreover, the chemical valence states of S, Cd, Zn, W, and Co elements were analyzed by the high‐resolution XPS spectra, and the XPS spectra of S 2p, Cd 3d, Zn 2p, W 4f, and Co 2p are shown in Figure 3b–e, respectively.…”

Conductive polymer mediated earth abundant Z-scheme g-C3N4/Fe2O3 heterostructure with excellent photocatalytic activity

“…7,[12][13][14][15][16] To improve the transport and utilization efficiency, cocatalysts with low overpotential for the hydrogen and/or oxygen evolution reaction (HER, OER) overpotential and suitable band structure were adopted. 7,17 Consequently, many cocatalysts (Pt, MoS 2 , transition metals and their compounds) have been introduced as the cocatalysts of g-C 3 N 4 for facilitating its photocatalytic hydrogen production efficency. 4,7,14,[18][19][20][21][22] In particular, iron is the second most abundant metal on the surface of earth and multiplex iron and its compounds have been extensively employed as cocatalysts, electrocatalysts and/or photocatalytic water oxidation and degradation catalysts.…”
