▎ 摘  要

NOVELTY - Non-noble metal catalyst comprises a carrier and an active center. The carrier comprises mesoporous oxide, a carbon material and/or a molecular sieve. The surface of the carrier has at least one functional group comprises hydroxy, carboxy, amino, ester group and the mercapto group. The density of the functional group is 0.05-5.0mmol.g-1. The active center is a cluster of metal atoms anchored by the confinement of the functional group on the surface of the carrier. The active center is a metal atom cluster anchored by a functional group on the surface of the carrier and the size of the metal atom cluster is smaller than that of the metal comprises molybdenum, indium, zinc, bismuth, tin, copper and/or gallium. The loading amount of the active center is 1.5-10 wt.%. USE - Used as non-noble metal catalyst comprising e.g. carrier. ADVANTAGE - The catalyst achieves double-high dispersion and loading capacity; has better catalytic activity; increases the turnover frequency (TOF) about 6-100 times; recycles and reuses the separated active components; has cheap raw materials; low cost; is conducive to large-scale production and has good application prospects. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing non-noble metal comprising (a) forming the metal precursor and carrier, where the particle size of the metal precursor and the carrier after the forming process are different, (b) physically mixing the metal precursor and the carrier, calcining at 100-800 degrees C with a pressure of 10-4Pa-1MPa for 5-100 hours in a migration atmosphere, cooling, obtaining the mixed sample and (c) physically separating the mixed sample obtained in the step (b), where the separated carrier component is the high dispersing non-noble metal catalyst; and (2) use of non-noble metal catalyst comprising gasoline hydrogenation reaction, synthesis gas conversion reaction and/or aromatization reaction of alkane.
