We have developed a novel NiRu/SiO2 bimetallic catalyst that significantly improves the efficiency of polyethylene hydrogenolysis, a key process in chemical recycling. This advancement reduces methane production by 69% compared to traditional Ru/SiO2 catalysts and increases the yield of valuable liquid products to 83.1C%. The research, which includes temperature-programmed reduction and desorption experiments, reveals a mechanism where the Ni-Ru alloy enhances hydrogen adsorption, leading to improved product selectivity. This work represents a significant step forward in the sustainable conversion of plastic waste into useful chemicals. (Xiangkun Zhang, Bingyan Sun, Zhigang Zhao, Tan Li, Marc Mate, Kaige Wang, Front.
