Atomically dispersed Ru catalysts for polychlorinated aromatic hydrocarbon oxidation

Abstract

The development of cost-efficient catalysts with good catalytic activity is an urgent task for polychlorinated aromatic hydrocarbons (PCAHs) oxidation. Herein, atomically dispersed Ru catalysts (denoted as Ru ADCs) proved by...

Controlled synthesis of Ru-single-atoms on ordered mesoporous phosphine polymers for microwave-assisted conversion of biomass-derived sugars to artificial sweeteners

“…Over several years, supported single-atoms have been shown as a new frontier in solid catalysis owing to their large surface-tovolume ratio, high selectivity, and unique role compared to metals in the bulk or nano-state. [13][14][15][16] Nevertheless, metal single atoms containing isolated metals at the support are challenging as they are thermodynamically unstable and aggregated to nanoparticles and clusters. [17][18][19] For their stabilization, metal-organic frameworks (MOFs), carbon, graphene, metal hydroxides, and metal oxides have so far been used as supports; yet, their impact on activity and stability requires further attention due to inadequate metal-support interactions.…”
