CeO2-modulated CoP derived from prussian blue analogue boosting hydrogen evolution reaction electrocatalysis

Rare earth oxide based electrocatalysts: synthesis, properties and applications

“…Song et al improved the catalytic HER performance of CeO 2 by extending the interface engineering strategy and introducing CoP components. 93 The novel CoP/CeO 2 heterostructures were successfully prepared by selective phosphating of the Co-PBA/CeO 2 hybrid precursors. The introduction of a CoP/CeO 2 heterogeneous interface can regulate the electronic structure, accelerate charge transfer and enhance the intrinsic activity of the active site.…”

Anchoring Ce-modified Ni(OH)2nanoparticles on Ni-MOF nanosheets to enhances the oxygen evolution performance

“…3b) of Ce-m-Ni(OH) 2 @Ni-MOF can be deconvoluted to two sets of Ce 3d 3/2 (V, V1, V2) and Ce 3d 5/2 (U, U1, U2, U3, U4) peaks, in which the peaks of V1, U and U2 can be assigned to two Ce 3+ , and the peaks of V, V2, U1, U3, and U4 represent Ce 4+ . [38][39][40] The Ni 2p 3/2 spectrum (Fig. 3c) of Ce-m-Ni(OH) 2 @Ni-MOF can be fitted to two peaks with a binding energy of 855.91 and 856.81 eV, which represent the presence of Ni 3+ and Ni 2+ , respectively.…”

Heterostructure Interface Engineering in CoP/FeP/CeOx with a Tailored d-Band Center for Promising Overall Water Splitting Electrocatalysis

“…The sheet-like CoP/CeO 2 heterostructure exhibits extraordinary OER performance originating from the interface-regulated oxygen vacancy and electronic interaction . In other heterophase materials, including NiFeLDH/CeO x , Cu 3 P/CeO 2 , and V-CoP/CeO 2 , CeO 2 can lower the needed energy for water dissociation and further promote the HER and even overall water splitting. − Our group has recently disclosed that the rod-inserting-cube CoP/CeO 2 and p–n CoP/CeO x heterojunctions exhibited higher HER activity than bare CoP due to the modulated electronic structure, especially for the d-band center. , Luo et al decorated CeO 2 on Co–Fe–P hollow hexagonal rods to enhance the HER activity by the optimization of the d-band center and hydrogen adsorption free energy . Nevertheless, the CeO 2 -induced metal phosphide interface with bifunctionality is rarely rare, yet of great interest with elaborate electronic structure modulation.…”
