Abstract (en)
[origin: WO2020224483A1] A method for preparing a highly dispersed ultrafine bimetallic shaped catalyst is provided. Said catalyst is obtainable by a method of solid-state seeded-growth strategy. Said method comprises: mixing an aromatic compound containing at least one N-group, a surfactant, an aldehyde compound and a first metal salt, wherein the first metal is one of Pd, Au, Pt and the like, and preparing a uniform solution; heating the solution to form a support and metal nanocluster seeds loaded on the support; uniformly introducing a second element into the support; during the hydrogenation reduction, the second element grows by taking the first metal nanocluster as a seed to obtain the bimetal-loaded catalyst support. The method can obtain the highly dispersed supported bimetallic catalyst with uniform ultrafine particles. The catalyst is easily shaped, easily separated and regenerated. The preparation process is green and energy-efficient, suitable for promotion, and therefore has a broad scope in the field of catalytic hydrogenation, oxidation and the like.
