Abstract Photocatalysis is considered to be a green and environment‐friendly technology since it can convert solar energy into other types of chemical energies. Over the past several years, metal‐organic frameworks (MOFs)‐based photocatalysts have received remarkable research interest due to their unique morphology, high photocatalytic performance, good chemical stability, easy synthesis, and low cost.

Abstract Phase engineering is an efficient strategy for enhancing the kinetics of electrocatalytic reactions. Herein, phase engineering was employed to prepare high‐performance phosphorous‐doped biphase (1T/2H) MoS 2 (P‐BMS) nanoflakes for hydrogen evolution reaction (HER). The doping of MoS 2 with P atoms modifies its electronic structure and optimizes its electrocatalytic reaction kinetics, which significantly enhances its electrical conductivity and structural stability, which are verified by
