Noble metal atomic-scale dispersed electrochemical catalyst capable of being amplified in batches and preparation method thereof

The invention belongs to the technical field of electrochemical catalysis, and particularly relates to a noble metal atomic-scale dispersed electrochemical catalyst capable of being amplified in batches and a related preparation method. The method comprises the following steps of: 1) preparation of an organic framework structure material; 2) chelation of the organic framework structure material and noble metal ions; 3) preparation of a noble metal macrocyclic organic matter precursor solution containing a decomposition type pore-forming agent; 4) hydrothermal crystallization treatment on the noble metal macrocyclic organic matter precursor solution to obtain noble metal macrocyclic organic matter precursor powder; and 5) further pyrolysis reduction and carbonization integration on the noble metal macrocyclic organic matter precursor powder. The preparation method of the catalyst is simple, the raw materials are easily available and low in cost, the noble metal utilization rate is increased, the catalyst has a
