Abstract
HighlightsNoble metals (Pt, Au) decorated Sr-incorporated g-C3N4 photocatalysts are fabricated via facile calcination and photo-deposition methods.The optical absorption and charge separation properties of the photocatalysts are remarkably improved and the Pt/0.15Sr-CN photocatalyst exhibited excellent activity for CO2 conversion.A quantum efficiency of 2.92% is predicted for CO2 reduction over the Pt/0.15Sr-CN photocatalyst at 420 nm wavelength, which is accredited to the improved optical absorption and enhanced charge separation via Sr-incorporation and the surface plasmon resonance effect of noble metal nanoparticles.
