Preparation of Ni/ZrO_2/SiO_2 Catalyst and its Application in Hydrogenation of CO_2 to Methane

摘要

The hydrogenation of CO_2 to CH_4 can realize the utilization of CO_2, which has an important implications to both the energy and environment. As a result of the low catalytic activity of the supported Ni/SiO_2 catalyst, the ZrO_2 is added to improve its catalytic performance by the impregnation method. The experimental results show that ZrO_2 is an effective promoter to enhance the low-temperature catalytic activity of Ni/SiO_2 catalyst.
