Controllable construction of hierarchical TiO2 supported on hollow rGO/P-HC heterostructure for highly efficient photocatalysis

Photocatalytic degradation of ammonia nitrogen using a Z-type nano-TiO2/LaMnO3 heterojunction

“…TiO 2 is one of the first photocatalytic materials discovered and widely studied and applied. [13][14][15] Due to its low cost advantages, stable chemical properties and adjustable structure, it is widely used in the fields of water treatment, air purification, environmental pollution control and energy conversion. The particle size of nano TiO 2 is 1/10th of the normal one, which allows the passage of ultraviolet (UV) light at shorter wavelengths and the increase of the active sites on the surface, thus enhancing its catalytic performance.…”

Facile fabrication of a BiOBr–Cu2+/TiO2 suspension for efficient equipment decontamination

“…5 TiO 2 , the most extensively studied photocatalyst, has been limited in practical application due to its high photogenerated charge recombination rate and low visible light responsivity. 6 Many tactics have been proposed for overcoming these bottleneck issues of TiO 2 , such as doping metal 7 or non-metal elements, 8 surface modification, 9 and constructing heterojunctions with other narrow band-gap semiconductors. 10 Among these, the construction of heterojunctions has received significant attention from researchers due to the unique electron transfer at the interface improving the separation of photogenerated electrons and holes.…”
