Abstract

original image

Changing the sheets: Hollow TiO2 porous nanosheets (HTPNs) are prepared on ITO glass through an improved TiO2 polycrystalline shell-assisted cation exchange by using ZnO porous nanosheets (grown by using indirect electrodeposition) as a template. Quantum dot-sensitized solar cells based on HTPNs exhibit a high performance, and other photoelectrochemical devices are expected to be prepared based on HTPNs.
