Abstract:

Selective hydrogenation has very important applications in the chemical industry such as synthesis of functional materials and purification of chemical products. In recent years, in order to reduce the impact of the greenhouse effect, the selective hydrogenation of CO2 into other valuable chemicals has become a research hotspot. Among them, the thermal catalysis is widely used, easy to obtain a variety of target products and high yield of products. At present, the heterogeneous thermal catalytic hydrogenation of CO2 to produce methane, methanol, light olefins and other high-value fuels and chemicals has made some progresses, but their development is still challenging. The preparation of high-efficiency catalysts is one of the keys. For a long time, researchers have been committed to solving the problem of catalyst activity and selectivity, and modifying the catalysts by doping with additives and adding functional carriers. In response to these problems, this article briefly introduces the background of the catalytic hydrogenation of CO2 and reviews the catalysts used in the heterogeneous thermal catalytic hydrogenation of CO2 into methane, methanol and light olefin products in recent five years. It is expected to provide a reference for the development of new catalysts in the heterogeneous catalytic hydrogenation of CO2.

Key words: Catalytic hydrogenation of carbon dioxide, Thermal catalysis, Methane, Methanol, Light olefins
