titleOfInvention | A kind of method for preparing catalyst carrier loaded with primary metal and secondary metal |
abstract | The invention provides a preparation method of a highly dispersed ultra-small bimetallic shaped catalyst, which is synthesized by a solid-phase seed crystal growth method. The method comprises: mixing at least one N-group-containing aromatic compound, surfactant, an aldehyde compound and a first-element metal salt as one of Pd, Au, Pt, etc. to prepare a homogeneous solution; The solution is heated to form a carrier and metal nanocluster seeds supported on the carrier; the second element metal element is uniformly introduced into the carrier; during the hydrogenation reduction process, the second element metal element grows with the first element metal nanocluster as a seed to obtain Supported bimetallic catalyst carrier. The method of the invention can obtain a highly dispersed supported bimetallic catalyst with uniform and fine particle size, the catalyst is easy to form, easy to separate and regenerate, the preparation process is green, energy-saving and popular, and has wide application in the fields of catalytic hydrogenation, oxidation and the like prospect. |
