H-Spill storage to maximize the catalytic performances of Pd-based bimetals@Ti₃C₂T_x MXenes in selective semihydrogenations

Abstract

Hydrogen spillover is an important theme for hydrogen storage and H-involving catalytic reactions. This work shows that catalytic reactivity and selectivity can be revealed by differentiating energetic characteristics of the...

Pt nanoparticles anchored by oxygen vacancies in MXenes for efficient electrocatalytic hydrogen evolution reaction

“…Two others peaks at 464.68 eV and 458.98 eV are assigned to the Ti–O 2p 1/2 and Ti–O 2p 3/2 , respectively. 54–56 This result clearly shows that the Al layer of MAX is etched off and the MXene is successfully generated. The generation of oxygen-containing groups on the surface of MXene nanosheets is beneficial for promoting the anchoring effect and inducing the deposition of Pt nanoparticles, where the interaction between the Pt catalyst and carrier contributes to the catalyst activity.…”
