Title: Atomic regulation of low-dimensional catalysts for hydrogen evolution reaction
Abstract:
Comprehensive utilization of the hydrogen energy is the current international research hotspot, and it is also the key technology to achieve the national goal of "carbon peaking and carbon neutral". We focus on the rational design and controllable synthesis of low-dimensional catalysts for electro or photo catalytic hydrogen evolution reaction (HER) and reveal the structure-activity relationship. Three catalytic systems for hydrogen evolution reaction will be introduced by atomic regulation of these low-dimensional catalysts: (1) interfacial engineering high efficient HER catalysts through strong metal (Co, Pd, Ir)-support (1T MoS2) interaction that induced phase transition by compressive strain. (2) HER catalysts based on two-dimensional metallene hydrides, in which H atoms stabilize the metallene and regulate the HER activity. (3) wet chemical synthesis of hydrogenated TiO2 with switchable defects for photocatalytic hydrogen evolution.
