The first part is ex-situ soft X-ray absorption spectrum measurement for the electrodeposited alloy. Since the X-ray direction into the Si3N4 window is reversible by rotating the holder, the valence state and surface effect of CoCu alloy for Co, Cu, and O elements is determined by the different signal depths between fluorescence yield (FY) and total electron yield (TEY) for the interface or bulk side. Thus, it verifies that the ex-situ reaction condition induces the surface oxidation as exposing to the air. The second part, we combine in-situ soft X-ray measurement and Electrochemical Quartz Crystal Microbalance (EQCM) methods to monitor the role of alloy catalyst in the CO2 reduction reaction(CO2RR) and hydrogen evolution reaction(HER). The operando result provides a comprehensive and real-time observation during the electrochemical reduction reaction process, in specific for chemical composition、surface quality, surface resistance formation, in order to estimate the divergence of electrochemical reaction. In the end, for HER reaction or CO2RR reaction, we point out that Co:Cu=1:2 alloy has appropriate current performance and structural stability. We provide an electronic configuration of the in-situ X-ray absorption spectrum for the real-time probing into the chemical valence state. Under the electrochemical reduction relative to the catalytic reaction, the insight into physical and chemical property is deeply understood and discussed.
