NOVELTY - Catalyst comprises transition metal nanoparticles and metal boride carrier (I) supporting the transition metal nanoparticles, where the transition metal nanoparticles comprise transition metals of group VIII and/or group IB. USE - The catalyst is used for catalyzing formic acid to produce hydrogen, multiphase catalytic reaction, hydrogen fuel cell, cathodic corrosion protection, boride target, boride nozzle composite material, boride ceramic material, boride coating, boride surface coating film material, wear-resistant material, energy chemical industry, petrochemical industry, carbon hydrogen bond activation, pharmacy, and preparation of hydrogen-containing water. ADVANTAGE - The catalyst has excellent high-temperature sintering performance. DETAILED DESCRIPTION - Catalyst comprises transition metal nanoparticles and metal boride carrier of formula: MmBn (I) supporting the transition metal nanoparticles, where the transition metal nanoparticles comprise transition metals of group VIII and/or group IB. M = metal, preferably Ti, Zr, Cr, Hf and W;and m:n = 0-4. An INDEPENDENT CLAIM is included for a method for synthesizing the catalyst, comprising (i) preparing transition metal nanoparticles and metal boride carrier separately, and (ii) loading the transition metal nanoparticles on the surface or inside of the metal boride support to prepare a metal nanocatalyst, stabilizing the metal nano-catalyst by heat treatment, and removing ligands and pollutants on the surface of the transition metal nano-particles at the same time to obtain the product, (or) (a) preparing metal boride carrier, and (b) using transition metal precursors to support metal nanoparticles on the metal boride carrier material by reduction or other loading methods to prepare metal nanocatalysts, stabilizing metal nano-catalyst by heat treatment, and removing ligands and pollutants on the surface of the transition metal nano-particles at the same time to obtain the product.
