Abstract
A preparation method of a Ni-based high-entropy oxide catalyst and its application in the preparation of syngas by carbon dioxide (CO) reforming of methane (CH) is provided, and it relates to the technical field of preparation of environmental catalytic materials. The catalyst is prepared by high-energy ball milling method. Using reversible Ni particles with high content as the active site of CHgas, other metals introduced by high-entropy strategy greatly reduce the carbon generated from CHcracking while activate CO. The prepared catalyst not only effectively overcomes the problem of poor stability of the Ni-based catalyst in COreforming of CH, but also promotes activation of COand improves the efficiency of COreforming of CHreaction. The provided preparation method of the high-entropy oxide catalyst is simple, stable, economical and reliable, and has a good development prospect in the industrial application field of COreforming of CHtechnology.
