Inverse In₂O_3-x/Ni interfaces via Ni₃InC_0.5 surface reconstruction for efficient CO₂ hydrogenation to methanol.

ABSTRACT: Catalyst surface reconstruction under reaction conditions is ubiquitous and crucial for creating unusual active sites, thereby enhancing catalytic performance. Here, we report the surface reconstruction of supported Ni₃InC_0.5 nanoparticles, leading to the formation of defective In₂O_3-x overlayers and inverse In₂O_3-x/Ni interfaces, driven by CO₂-induced selective surface oxidation during CO₂ hydrogenation. The synergy between In₂O_3-x overlayers and inverse In₂O_3-x/Ni interfaces facilitates CO₂ adsorption and activation, as well as the following hydrogenation of HCOO^* and CH_xO^* intermediates, enabling efficient methano
