Trapping [PMoO] clusters into pre-synthesized ZIF-67 toward Mo Co C particles confined in uniform carbon polyhedrons for efficient overall water splitting.

Bi-transition metal carbides (BTMCs) are promising in catalytic fields, but the synthesis of small-sized BTMCs remains a challenge. Here, Mo Co C (mainly below 20 nm in size) confined in uniform carbon polyhedrons (Mo Co C@C) was synthesized based on trapping [PMoO] (PMo) clusters into pre-synthesized, uniform ZIF-67 (PMo/ZIF-67).

Hierarchical whisker-on-sheet NiCoP with adjustable surface structure for efficient hydrogen evolution reaction.

We have reported the synthesis of hierarchical whisker-on-sheet (HWS) NiCoP anchored on Ni foam with adjustable surface structure for efficient hydrogen evolution reaction (HER). The HWS NiCoP was obtained by controllable phosphidation of HWS Ni-Co-carbonates hydroxide precursor grown on Ni foam (NF). The experimental parameters were optimally tuned to understand the formation process of the precursor and to regulate the microstructure of the materials.
