Fabrication of unique three-dimensional CdS nanosheets/TiO2 nanosheets hierarchical heterostructure as photoelectrode for enhancing photoelectrochemical performance

Combination of alkali treatment and Ag3PO4 loading effectively improves the photocatalytic activity of TiO2 nanoflowers

“…21–1272], respectively. 31–34 After alkali treatment, the diffraction peaks of OH/TiO 2 and TiO 2 are consistent, and no other diffraction peaks appear, indicating that alkali treatment does not affect the crystal structure of TiO 2 . After in situ growth of Ag 3 PO 4 , the new diffraction peaks at 2 θ values of 20.84°, 29.66°, 33.26°, 36.54°, 42.44°, 47.75°, 52.64°, 54.98°, 57.24°, 61.60°, 65.80°, 69.90°, 71.84°, 73.82° and 77.69° are observed, which can be indexed to the {110}, {200}, {210}, {211}, {220}, {310}, {222}, {320}, {321}, {400}, {330}, {420}, {421}, {332} and {422} crystal planes of Ag 3 PO 4 [JCPDS No.…”
