Inducing a deep impurity level in Li2SnO3 by ionic Bi–O bonding to enhance light absorption in photocatalysis

Mechanism of p-Type Heteroatom Doping of Lithium Stannate for the Photodegradation of 2,4-Dichlorophenol: Enhanced Hole Oxidative Capability and Concentrations

“…Figure a shows powder XRD patterns of as-synthesized Li 2 SnO 3 and Li 2 Sn 0.90 In 0.10 O 3 . The two samples exhibit identical XRD patterns, which can be assigned to orthorhombic Li 2 SnO 3 (JCPDS 076-1149) . Notably, the strongest peak located at approximately 17.9° can be indexed to the (002) crystal plane.…”

“…The two samples exhibit identical XRD patterns, which can be assigned to orthorhombic Li 2 SnO 3 (JCPDS 076-1149). 38 Notably, the strongest peak located at approximately 17.9°can be indexed to the (002) crystal plane. The inset of Figure 1a indicates that the strongest peak was shifted to a lower 2θ value relative to those of pristine Li 2 SnO 3 .…”

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.…”
