Interfacial engineering of metal–organic framework derived hierarchical CoP–Ni₅P₄ nanosheet arrays for overall water splitting

Abstract

To sustainably develop an economical, efficient and stable non-noble metal hydrogen production catalyst is still an essential challenge. Herein, the hierarchical CoP-Ni5P4 nanosheet arrays self-supported electrode (CoP-Ni5P4/NF) for water splitting...

Constructing Molybdenum Phosphide@Cobalt Phosphide Heterostructure Nanoarrays on Nickel Foam as a Bifunctional Electrocatalyst for Enhanced Overall Water Splitting

“…A set of spin-orbit splitting peaks at 234.20 and 231.20 eV shown in Figure 2d belong to Mo 3d 3/2 and Mo 3d 5/2 peaks on the NPs. Figure 2e shows that in the Co 2p spectrum, the signals of a set of spin-orbit splitting peaks at 779.20/795.06 eV originate from Co 2p 3/2 and Co 2p 1/2 in Co-P [26,27]. A group of peaks at 780.7 and 796.58 eV are the signals of Co 2p 3/2 and Co 2p 1/2 of the Co-O bond caused by surface oxidation of the material, and a group of satellite peaks at 784.45 and 800.95 eV [28,29].…”

Bi-metallic [Cu/Co(6mna)2]n metal organic chalcogenolate frameworks as high-performance electro-catalysts for dye-sensitized solar cells: a ligand-assisted bottom-up synthesis

“…Metal–organic frameworks (MOFs) have been extensively investigated as superior electro-catalysts for various electrochemical devices, including water splitting devices, 1 supercapacitors, 2 sensors 3–5 etc. Within a MOF architecture, the unsaturated coordination at metal clusters is considered as active sites to trigger numerous electrochemical reactions, while the adjustable organic ligands are expected to deliver variable pore configurations and functionalities for specific molecules.…”

A pillar-layered Ni2P–Ni5P4–CoP array derived from a metal–organic framework as a bifunctional catalyst for efficient overall water splitting

“…24 The synergistic effect of CoP and Ni 5 P 4 is also noted to reduce the adsorption energy of the intermediate by the d-band center shift, facilitating efficient overall water splitting. 25 Moreover, heterogeneous CoP–FeP, 26 Cu 3 P–Co 2 P, 27 Ni 5 P 4 @FeP, 28 Ni 2 P–VP 2 /NF, 29 etc . 30 have demonstrated enhanced HER/OER kinetics through synergistic effects.…”
