Strong metal-support interaction induced by Pt-O-Bi bonding in mesoporous anatase TiO₂ for base-free catalytic biomass valorization.

ABSTRACT: The exceptional catalytic activity of bimetallic or trimetallic catalysts has been demonstrated in various reactions. However, in-depth understanding of the intricate metal-support interactions remains crucial yet challenging. Herein, a well-defined, highly active, Pt single-atom dominant Pt-Bi/TiO₂ catalyst with mesoporous crystalline anatase structure was fabricated via an in situ one-pot evaporation-induced self-assembly method and employed for the base-free oxidation of biomass-derived 5-hydroxymethylfurfural (HMF) to value-added chemicals in aqueous media. Our findings demonstrate that Bi incorporation not only greatly reinforces the strong metal-support interaction between Pt and the support, but also benefits the Pt distribution, enabling the formation of single-at
