Structurally controlled ZnO/TiO2 heterostructures as efficient photocatalysts for hydrogen generation from water without noble metals: The role of microporous amorphous/crystalline composite structure

Amorphous and Crystalline Sodium Tantalate Composites for Photocatalytic Water Splitting

“…33 Similar amorphous-crystalline composite samples have been demonstrated to form heterojunctions and improve separation of photoexcited charges if the thickness of the amorphous region is small. [45][46][47][48][49] In our case, the amorphous matrix can reach distances of several 100 nm, however, as it consists of a porous network, the minimum diffusion path for charge carriers through the amorphous matrix is only a few nanometers, as shown by the HR-TEM observation (Figure 3a-b and S6c,d). We attributed the high photocatalytic activity to the porous nature of the amorphous matrix, which makes the diffusion of charge carriers to the electrolyte interface quite facile.…”

Ag/ZnO/graphene oxide heterostructure for the removal of rhodamine B by the synergistic adsorption–degradation effects

“…Thus the development of well-defined ZnO-based heterostructures with narrowed band gap, excellent light absorption and highly efficient dye adsorption has been actively pursued [13][14][15][16][17][18][19][20][21].…”

Hierarchical flower-like titanium phosphate derived from H-titanate nanotubes for photocatalysis

“…Photocatalytic degradation is considered to present an attractive strategy for water decontamination for its fast and complete mineralization of pollutants without leaving any harmful residues. Till now, most studies are focused on TiO 2 -based photocatalysts [2][3][4][5][6][7][8]. Recently, phosphate-based materials have been one of research hotspots because of their unique open framework structure.…”
