Compared with TiO2-x or CoFe2O4, TiO2-x/CoFe2O4 heterojunction displayed enhanced sono-oxidation performance, and their immobilization onto diatomaceous earth (DE) further increased the oxidation rate. The effects of various parameters on sono-oxidation efficiency were studied, such as pH, IBP ...
Here we report a new electrode material, heavy nitrogen-doped (9.29 at.%) black titania (TiO2x:N). This unique hybrid material, consisting of conductive amorphous shells supported on nanocrystalline cores, has rapid N-mediated redox reaction (TiO2xNy + zH+ + ze TiO2xNyHz), especially in ...
