CO2 photocatalytic reduction to fuels: Enhanced methanol selectivity by loading Ag on NaNbO3

Autor: F. F. Al-Adel, Abul Lais, Mohammed A. Gondal

Publikováno v: AIP Conference Proceedings.

Pure and Ag-loaded NaNbO3 were synthesized, and characterized by PL, Raman, XRD and FE-SEM. They were subsequently applied for the photocatalytic CO2 reduction to fuels process, wherein methanol and formic acid were detected. Loading silver significa
