Photoelectrochemical properties of the crednerite CuMnO2 and its application to hydrogen production and Mn+ reduction (Mn+ = Cd2+, Pd2+, Zn2+, Ni2+, and Ag+)

Monolithic CuMnO2-Nanosheet-Based Catalysts In Situ Grown on Stainless Steel Mesh for Selective Catalytic Reduction of NO with CO

“…Parts e and f of Figure show the XPS spectra of O 1s before and after the CO-SCR test. Obviously, the fitted peak located at 529.6 eV is ascribed to the lattice oxygen (O α ), while the fitted peak located at 531 eV belongs to the surface-adsorbed oxygen species (O β ). , It can be seen that the proportion of O β decreases from 59.6% to 43.5% after the CO-SCR test, as shown in Figure f and Table S1. , The decrease in the surface oxygen O β content is also solid proof for the formation of SSOVs. Moreover, the overall spectra in Figure S5a,b show the coexistence of Cu, Mn, and O elements in the CuMnO 2 nanosheet before and after the CO-SCR test.…”

The Use of Copper-Based Delafossite to Improve Hydrogen Production Performance: A Review

“…Both processes proceeded concurrently, with no observable photoactivity under pH 7, showing that S 2− played a critical role. Carriers were transferred iso-energetically between CuAlO 2 and the electrolyte, with the help of produced band gap states acting as strong relays [109]. The overall reaction is governed by the momentary arrival rate of electrons at the contact, and the greater thermal photoactivity observed is connected to enhanced electronic mobility [110].…”
