Abstract: A preparation method and an application method of a Ni—Co bimetallic catalyst for dry reforming of methane are provided, which relate to the field of catalytic material preparation technologies. The preparation method uses Ni and Co as active components of a catalyst for dry reforming of methane, alkaline earth metal salt as CO2 adsorbent, and uses an immersion method to prepare a Ni—Co bimetallic catalyst with high performance. The prepared catalyst not only effectively overcomes a problem of poor stability of Ni-based catalysts, but also promotes the adsorption of CO2 and improves the efficiency of dry reforming of methane. The preparation method of the Ni—Co bimetallic catalyst is simple and cost-effective, and exhibits excellent catalytic performance and stability in dry reforming reaction of methane.

Abstract: An acid-functionalized polyolefin material that can be used as an acid catalyst in a wide range of acid-promoted chemical reactions, wherein the acid-functionalized polyolefin material includes a polyolefin backbone on which acid groups are appended. Also described is a method for the preparation of the acid catalyst in which a precursor polyolefin is subjected to ionizing radiation (e.g., electron beam irradiation) of sufficient power and the irradiated precursor polyolefin reacted with at least one vinyl monomer having an acid group thereon. Further described is a method for conducting an acid-promoted chemical reaction, wherein an acid-reactive organic precursor is contacted in liquid form with a solid heterogeneous acid catalyst comprising a polyolefin backbone of at least 1 micron in one dimension and having carboxylic acid groups and either sulfonic acid or phosphonic acid groups appended thereto.
