▎ 摘 要
NOVELTY - Method for preparing a two-dimensional layered glycerin-oxidized nanocatalyst, involves (i) dissolving cerium nitrate in an ethanol solution, mixing with a graphene-mesoporous silicon composite, drying and calcining to obtain a composite material, (ii) mixing and heating the composite material with a strong alkali solution, washing, filtering and drying to obtain a graphene-loaded two-dimensional layered ceria carrier, and (iii) uniformly mixing graphene-loaded two-dimensional layered ceria carrier and a sol gel dispersed with gold nanoparticles to obtain a gold-loaded two-dimensional ceria glycerol selective oxidation catalyst. USE - The method is useful for preparing a two-dimensional layered glycerin-oxidized nanocatalyst. ADVANTAGE - The catalyst has high product selectivity and catalytic activity, has novel structure, adopts simple and environmentally-friendly preparation process, and has broad application prospect and important significance of in-depth research.
