| titleOfInvention | Low-noble metal shell catalyst prepared by reduction of polyhydroxy aldehyde ketone and preparation method thereof |
| abstract | The invention belongs to the technical field of energy catalysis, and particularly relates to a low-noble metal shell catalyst prepared by reduction of polyhydroxy aldehyde ketone and a preparation method thereof. The invention provides a low-noble metal shell alloy catalyst and a method. The preparation steps of the catalyst are as follows: 1) chelating and dispersing core metal ions, and freezing for stabilization; adding a reducing agent for combination, and further freezing to obtain a reducing precursor; 2) ultrasonically dispersing a carbon carrier in a solution with stable surfactant, adding a reducing precursor, and heating for reducing to prepare a core metal; 3) coating a stable metal transition layer; 4) reducing polyhydroxy aldehyde ketone of shell metal; 5) aging and growing the crystal; 6) and (4) centrifugal drying and heat treatment. The obtained catalyst has oxygen reduction activity superior to that of commercial Pt/C, is simple in preparation method, and has important value in the fields of oxygen reduction catalytic systems, electrocatalysis, fuel cells and the like. |
