Recently, the optical drive carbon neutralization team of our hospital has made important progress in the field of high -entropy light thermal catalytic. The two -dimensional high -entropying coordinated by the copper -based catalyst improves its optical and thermal CO2 hydrogenation activity and stability, and coupling with the photometer system Realized the efficient sunlight CO2 CO2, and the related work "CU-BASED HIGH-ENTROPY TWO-DIMENSIONAL OXIDE AS Stable and Active Phothermalmalmalmalmalmalmal Catalyst" was published in "Nature Communications" （2023, 14: 3171）. Dr. Li Yoguang is the first author and communication author of the paper. Professor Ye Jinhua and Professor Zhang Liqiang of Yanshan University as the co -communication author.
Copper nano -material is the benchmark catalyst with many light thermal catalytic. It is limited to the lower Taman temperature (about 400 ° C). Copper -based catalysts are easy to gather in the process of high temperature light thermal catalytic to reduce their service life. The catalytic stability and activity of the coordinated enhancement of the copper -base light thermal catalyst is a major challenge facing. In this work, Li Yoguang cooperated with Professor Ye Jinhua and Professor Zhang Liqiang to synthesize the high -entropy two -dimensional (2D) materials of six yuan to eleven yuan with polyethylene pyrirol (PVP) template method. The optimized copper-based high-entropy two-dimensional material remains stable between 400-800 ° C, and CO2 hydrogenation CO performance reaches 417.2 mmol G-1H-1 at 500 ° C. Combine the copper-based high-entropy two-dimensional materials with optical thermal devices. Under the two standard sunlight, the generating rate of light thermal catalytic CO2 hydrogenation CO reaches 248.5 mmol G-1H-1. The efficiency was 36.2%, and the outdoor optical catalytic CO output of 7 consecutive days reached 571 L. The results show that high -entropy two -dimensional materials provide a new path for coordinated improvement of catalyst stability and activity, and expand the scope of application of light thermal catalysis.
