Enhanced Photogenerated Hole Oxidation Capability of Li2SnO3 by Sb Incorporation in Photocatalysis Through Band Structure Modification

Rational Modulation of Effective Mass Near Band Edge of Li2SnO3 to Increase Photogenerated Carrier Separation Ratio and Photocatalytic Performance

“…The crystal structures of the as-prepared catalysts were investigated by powder XRD. Li 2 SnO 3 crystallizes with a monoclinic crystal structure with space group C 2/ c . , As shown in Figure a, all of the XRD patterns could be indexed to that of Li 2 SnO 3 (JCPDS 076-1149), and no impurity phases were observed, suggesting that Pb and Ge were successfully substituted at Sn sites. The Rietveld refined XRD patterns and lattice parameters of the as-prepared photocatalysts are shown in Figure b, Figure S1, and Table S3, respectively.…”
