Improved Surface Functional and Photocatalytic Properties of Hybrid ZnO-MoS2-Deposited Membrane for Photocatalysis-Assisted Dye Filtration

“…After exposure to UV illumination at 60 min, the MB flux of the ZnO-MoS 2 PCM has exhibited a considerable increase of about 20% at the end of the 2 h of UV exposure. This prominent effect is certainly attributed to the photocatalytic activity of the hybrid ZnO-MoS 2 layer that eventually reduced the fouling layer resistance caused by the MB dye solutes [47]. The surface-deposited layer has offered to overcome the membrane resistance and enabled to improve the productivity while rejecting the MB feed solution.…”

Photocatalytic Degradation Properties of Nano‐lignocellulose⋅NiNiO/GR‐TiO2 Hollow Rod Composite for Methylene Blue

“…It has high specific surface area negative charge and rich π electrons, which can effectively reduce electron and hole recombination in the catalytic process. [21][22][23][24] Wang et al [25] synthesized TiO 2 /BiOBr coupled composite photocatalyst by situ direct growth method under microwave radiation. Biological Br has an inhibiting effect on the growth of TiO 2 particles, which expands the surface area and enables the effective separation of electron-hole pairs between biological Br and amorphous TiO 2 .…”

Theoretical calculation and experiment study on the electronic structure, microstructures and photocatalytic activity of N–Al codoped TiO2

“…Thus, it is necessary to seek some cheaper and accessible metal elements to be doped into TiO 2 to improve the photocatalytic activity under visible light. 7,8 In recent years, it has been proven that the optical absorption of TiO 2 can be increased using a dopant, including a nonmetal and metal. Meng et al 9 pointed out that TiO 2 codoped with N and a transition metal could display photocatalytic activity under visible light.…”
