Photoelectrocatalytic process in situ spectroscopic image analysis system developed acceptance

[Chinese instrument network instrument research and development] May 26, Chinese Academy of Sciences, Xinjiang Institute of physical and chemical technology research and development of Chinese Academy of Sciences equipment development project "Photoelectrocatalytic process in situ spectroscopic image analysis system" has passed the expert acceptance of the Chinese Academy of Sciences Bureau of Finance Bureau organization.

Zhang Hongsong, director of the equipment office of the Chinese Academy of Science and Technology Bureau, an acceptance expert, and Cui Wangcheng, deputy director of Xinjiang Physical and Chemical Institute, and related personnel of the project undertaking unit participated in the acceptance meeting.

Wang Chuanyi, the project leader, introduced the project situation and the test outline of the performance indicators achieved by the system. The expert group reviewed the test outline and conducted field tests of various performance indicators. Zhang Hongsong introduced the specific requirements for acceptance and introduced the list of acceptance experts. Wang Chuanyi made work reports, financial reports and user reports. The leader of the test team made test reports. The acceptance team experts reviewed the relevant materials and financial files of the project. After the comprehensive evaluation of the test group experts and the acceptance group experts, the expert group highly evaluated and agreed that the project team completed the research and development tasks specified in the implementation plan, reached the project's expected goals, and agreed that the project passed the acceptance.

This project integrates the sensitive non-linear laser spectroscopy system of the surface interface with the time and space resolution detection technology of photoelectrocatalytic process regulation, and establishes the photoelectrocatalytic process in-situ spectroscopic image analysis system, which can perform time-resolved pump detection of nonlinear laser spectroscopy. The system laser pulse width is femtosecond, the pulse repetition frequency is 1000Hz, the output laser wavelength is 237-2600nm, and the frequency spectrum detection range is 600-4300cm-1. At the same time, photoelectrocatalytic tracking, time-resolved pump detection and in-situ image chemical analysis can be performed. . The system has been applied to the interface research of photoelectrocatalysis and liquid-gas meter. The experts agreed that the implementation of this project can obtain the microscopic information on the sensitivity of the monolayer/sublayer, which is helpful for understanding the photoelectrocatalytic reaction mechanism. It is an effective extension of the existing research methods.
