NiCo₂O₄ nanosheets as a novel oxygen-evolution-reaction cocatalyst in situ bonded on the g-C₃N₄ photocatalyst for excellent overall water splitting

Abstract

NiCo2O4 is in situ assembled on g-C3N4 and works as a novel oxygen-evolution-reaction cocatalyst to promote photocatalytic O2-evolution reaction, then Pt–NiCo2O4 dual cocatalyst loaded g-C3N4 achieves photocatalytic overall water splitting.

NiAl‐LDH In‐Situ Derived Ni2P and ZnCdS Nanoparticles Ingeniously Constructed S‐Scheme Heterojunction for Photocatalytic Hydrogen Evolution

“…The combination of two or more different semiconductors, due to their different energy band structure and potential difference, will cause the separation of e À -h + to accelerate. [20][21][22] The construction of heterojunction compounds can significantly improve the hydrogen evolution efficiency of the catalyst. [23][24][25] Layered double hydroxides (LDH), also known as a hydrotalcite-like compounds, consists of a layer of positively charged metal hydroxide and exchangeable anions ([M 2 + 1-x M 3 + x (OH) 2 ] (A n À ) x/n •mH 2 O).…”

ZIF-67 derived hierarchical hollow Co3S4@Mo2S3 dodecahedron with an S-scheme surface heterostructure for efficient photocatalytic hydrogen evolution

“…In order to cope with the gradual depletion of traditional energy and the increasingly severe environmental problems, the exploration of clean and green energy sources is urgent. 1–3 As one of many clean energy sources, hydrogen energy has attracted wide attention due to its high heating value and conversion efficiency. 4 The extensive use of solar energy to realize its efficient conversion to hydrogen energy has become the goal of many researchers in photocatalytic hydrogen evolution.…”

Bioinspired spike-like double yolk–shell structured TiO2@ZnIn2S4 for efficient photocatalytic CO2 reduction

“…4g and is related to S 2p, which is consistent with the S element of ZnIn 2 S 4 . 24,51–54 However, the XPS peaks of Ti 2p and O 1s of D-Y-TiO 2 @ZnIn 2 S 4 -3 shift to the higher binding energy levels when compare with the XPS signals of D-Y@TiO 2 , demonstrating the strong connection between D-Y-TiO 2 and ZnIn 2 S 4 .…”
