▎ 摘　　要

NOVELTY - Preparing an atomically dispersed metal catalyst (125) involves depositing atomically dispersed metal onto a support (120) by magnetron sputtering to directly form a catalyst containing metal particles with mean diameter up to 1 nm dispersed on the surface of the support. The support is water-insoluble. USE - Preparing atomically dispersed metal catalyst e.g. thermal catalyst, electrocatalyst or photo catalyst (all claimed). ADVANTAGE - The atomically dispersed metal catalyst has high activity and selectivity in many catalytic reactions. The catalyst is thermally stable, photoactive and electrically conductive. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of magnetron sputtering deposition of metal to form an atomically dispersed metal catalyst. 101Argon ions 102Metal target 103Atoms 105Drive shaft 106Sample holder 120Support 125Catalyst
