Abstract

Cation defects in La and Cr co-doped SrTiO3 have been specifically studied for elucidating correlations between defect concentration, electronic properties, structural properties and photocatalytic activity for H2 production. A moderate cation deficiency can promote the photocatalytic activity by ca. 3 fold, which can be mainly linked to the enhancement of the charge carrier mobility.
