title: Construction of self-supported three-dimensional TiO2 sheeted networks with enhanced photocatalytic activity.
abstract: The degradation of toxic gases and liquids using a catalyst and solar energy is an ideal method, compared with landfill and combustion methods. The search for active semiconductor photocatalysts that efficiently decompose contaminations under light irradiation remains one of the most challenging tasks for solar-energy utilization. In this work, free-supporting three-dimensional (3D) nanosheeted hierarchical porous tungsten, titanium, and tin oxide networks were obtained by a facile Lewis acid catalytic binary template route. These networks possess large macroscopic scale (millimeter-sized) and hierarchical macro/mesoporous nanostructure with high surface area and large pore volume. Photocatalytic degradation of Azo dyes demonstrated that the nanosheets-constructed hierarchical porous networks have high photocatalytic activity and stability. The present synthetic route can serve as the new design concept for functional 3D layered porous nanostructures.
