Apr 12,2024

Recently, Hangzhou Pufico Air Spreading Equipment Co., Ltd. has cooperated with relevant research groups of Jiaxing University, Zhejiang University of Technology and Adelaide University in Australia to convert CO by photocatalysis.2The latest research progress has been made in the field. The relevant research results are entitled "Titanium carbide sealed cadmium sulfide quantum dots on carbon, oxygen-doped boron nitride for enhanced and durable photochemical carbon dioxide reduction" and are published online in the international TOP journal Journal of Colloid and Interface Science (SCI Area 1, Impact Factor 9.9) (2 024, 665, 443-451. DOI: 10.1016/J. JCIS.2024.03.139). Dr. Shen Zhangfeng of Jiaxing University and Yang Yang, a graduate student of Zhejiang University of Technology, worked together. The corresponding authors are General Manager Cheng Xiaohua of Pufico and Professor Wang Yangang of Jiaxing University.

The utilization of carbon resources is an indispensable link to achieve the goal of carbon neutrality. CO2As a renewable C1 resource, its capture and resource utilization is a powerful supplement to the natural carbon cycle. In many CO2In the conversion path, the use of sunlight to achieve CO2Photocatalytic technology for the conversion of hydrocarbon fuels is undoubtedly the most energy-efficient and green strategy. The key to realize this path is to develop new, efficient and stable semiconductor photocatalytic materials. However, most of the semiconductor photocatalyst for CO2 adsorption and light utilization is very low, greatly limiting the CO2The photocatalytic conversion efficiency of the catalyst also has the problem of stability. Around the above scientific problems, we constructed the Mxene/CdS QDs/BN ternary photocatalytic material from the perspective of energy level matching, and realized the encapsulation of CdS quantum dots on the BN surface by using the layered titanium carbide Mxene material, and the interface space between the three became CO.2The place of photocatalytic reaction. The material combines BN with good CO2Capture and activation ability, CdS QDs absorption of visible light, MXene excellent electronic conduction and storage capacity and other advantages, thus greatly improving the CO2conversion efficiency to solar fuel. At the same time, the coverage of Mxene can effectively inhibit the light corrosion of CdS and improve the stability of the material under light. The result of this research is the company's commitment to "methanol hydrogen production/water electrolysis hydrogen production-CO2Adsorption separation-CO2The development of key materials and technologies in the artificial carbon cycle system of "hydrogenation to methanol" has laid a solid foundation.
