New catalyst technology promotes green and efficient development of chemical industry

In today's global chemical industry, the innovation and application of catalyst technology is becoming a key factor in promoting the green and efficient development of the industry. Recently, a research team from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, has made significant progress in the study of hydrogen production from fully decomposed water over broad spectrum trapping photoCatalysts. They found that the strong interaction of metal carriers can significantly promote the interfacial charge separation and water oxidation performance of Ir/BiVO4 photocatalyst system, and then established a highly efficient “Z” mechanism of total decomposition of water hydrogen production system, whose apparent quantum efficiency of hydrogen production at room temperature reaches 16.9%.

In addition, the development status of the chemical catalyst industry has also attracted much attention. According to the analysis, the consumption of chemical catalysts in China is directly related to the production of chemical products, and the consumption of chemical catalysts in China was about 395,000 tons in 2017, with a year-on-year growth of 4.3%. Among them, the catalyst application scenario in the petrochemical field is the most extensive, with the demand accounting for 70% of the total demand for chemical catalysts.

These advances not only demonstrate the important role of catalyst technology in improving the efficiency of chemical reactions and enabling large-scale production, but also provide new ideas for promoting photogenerated charge separation, which is expected to lay the scientific foundation for constructing a new system of efficient photocatalysis. With the improvement of environmental protection requirements and the need for sustainable development, the chemical catalyst industry is developing in the direction of greater efficiency and environmental protection.
