Recently, Li Can, a member of the Chinese Academy of Sciences and a researcher at the State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Li Rengui, a researcher at the Dalian Institute of Chemical Physics, proposed the establishment of a standard test method and efficiency certification center for solar photocatalytic water splitting. The initiative joined forces with researchers such as Kazunari Domen, professor of the University of Tokyo, Japan, Wang Lianzhou, professor of the University of Queensland, Australia, Kazuhiro Sayama, professor of the National Institute of Industry of Japan, and Liu Gang, a researcher of the Institute of Metal Research of the Chinese Academy of Sciences, to clarify the basic concept of photocatalysis and point out that particle photocatalysts split water. The existing sources of error in the research clarify the pros and cons of different efficiency performance methods, and propose a comparison method to standardize the performance of solar photocatalysis, especially for the two important indicators in the field of solar photocatalytic water splitting research-quantum efficiency and solar hydrogen production efficiency , Proposed a standardized standard test method, and recommended that it be used as the basis for publishing related articles in important international journals. Solar energy photocatalytic water splitting to produce hydrogen is a cutting-edge scientific topic in the international scientific field, which has attracted much attention from the academic community. Its basic scientific issues involve photoelectric conversion, photochemical conversion and photo-generated charge dynamics. Once progress is made in this process, it will be possible to fundamentally The above changes in the current structure of the energy and chemical industries are of great significance to alleviating the problems of climate change, energy security and sustainable development of the ecological environment that humans are currently facing. In the past few decades, many academic papers have been published in this field, and the number of published articles has increased exponentially year by year. However, the lack of uniform efficiency certification and evaluation standards in this research field at home and abroad has caused problems such as a large number of efficiency names and poor data comparability in academic papers published in this field. It is urgent to establish standardized and unified standard test methods and efficiency certifications. Center to better regulate the healthy development of this field. The solar photocatalytic water splitting reaction is a complex process involving multi-electron transfer. It is restricted and affected by factors such as light absorption efficiency, charge separation efficiency and catalytic reaction efficiency. The experimental conditions and parameters are difficult to accurately control and the experimental errors are large. In addition, due to the difference in test experimental methods, it has become a common phenomenon in this research field that there may be deviations in important experimental data. Throughout the development of other related fields, such as the solar cell field, there have been many internationally accepted evaluation and testing standard methods and certification centers. Among them, the National Renewable Energy Laboratory (NREL) of the United States is the certification center to undertake The certification test of battery efficiency and the authoritative publication of the results of leading the world's solar cell efficiency every year make the research data published by different laboratories comparable and play an important role in the development of this field. In order to better implement the initiative, the article proposes to lead by scientists from various countries, try to establish efficiency testing and certification centers in their respective countries, and calibrate each other between the centers established in various countries, and gradually promote internationally unified standards and certifications, which have been initially reached. Agreement to establish standard testing centers in China, Japan and other countries. With the support of the National Natural Science Foundation of China, my country’s first basic science center in the field of solar photocatalysis, the "Artificial Photosynthesis" Center, has been approved to be established in the Dalian Institute of Chemical Technology in 2020. The center will be led by Li Can and will begin preparations. China Solar Energy Photocatalytic Water Decomposition Standard Efficiency Test Center. At the same time, representatives of Japanese scientists Kazunari Domen and Kazuhiro Sayama will establish a photocatalytic efficiency test center in Japan at the University of Tokyo and the National Institute of Industrial Research in Japan. The establishment of these standard efficiency test centers will be dedicated to standardizing the experimental process, experimental data and data representation in the field of solar photocatalysis, improving related experimental skills, improving the credibility and accuracy of articles published in the field of solar photocatalysis, and promoting the Healthy and sustainable development in the field of basic scientific research. The initiative is titled Efficiency Accreditation and Testing Protocols for Particulate Photocatalysts towards Solar Fuel Production, which is published as a Perspective article in Joule.
