Experimental study reveals enhanced visible-light photocatalytic carbon dioxide reduction using mixed-phase sodium titanates, highlighting potential avenues for solar fuel synthesis.
Herein, we reported the method of synthesis of sodium titanates using metal-ammonia solution and their photocatalytic activity for the gas-phase reduction of carbon dioxide under visible light. The results of physicochemical measurements showed that the obtained samples resemble multiphase systems containing Na2Ti4O9, Na4Ti5O12, and Na0.8Ti4O8 of cylindrical forms. They demonstrated perfect adsorption of visible light and improved activity in the investigated process.
