The project titled “The Operando Raman/IR Characterization System”, a research item in the CAS Renovation Program for Functional Technique Development of Instruments, passed official acceptance-check on 31th July. The research work was done by Dr. Lin Li of the 1502 Research Group of DICP.

The Acceptance-Check Experts Group first listened to the research report, the budget report and the test-operation report, then inspected the research documents and conducted on-site verification of the performance of the system. Finally, the experts gave the following conclusions: an advanced operando Raman/IR system have been developed successfully. It can be used for in situ characterization of adsorption and catalysis under the real reaction condition. The technique has been applied in the studies of gold catalysis. The research work has realized the target of instrumental functionalization, and fulfilled the contract requirements. Finally, the experts agreed unanimously that the project passed the acceptance-check.

note：The term operando spectroscopy implies that the catalyst characterization information is being conducted simultaneously with online product analysis.
