Fouling of TiO2 induced by natural organic matters during photocatalytic water treatment: Mechanisms and regeneration strategy

Self-assembly of a heterogeneous microreactor with carbon dots embedded in Ti-MOF derived ZnIn2S4/TiO2 microcapsules for efficient CO2 photoreduction

“…46 For ZIS/TiO 2 and CDs/ZIS/TiO 2 , the peaks of the amino group disappeared, and more C–C and CO groups emerged, indicating the presence of surface functional groups such as hydroxyl and carboxyl around catalysts. 47 From the high-resolution spectrum of N 1s (Fig. S12c†), the difference between NH 2 -MIL-125 and ZIS/TiO 2 can be seen clearly.…”

P Doping Promotes the Spontaneous Visible-Light-Driven Photocatalytic Water Splitting in Isomorphic Type II GaSe/InS Heterostructure

“…For coordinating the contradiction between energy and environment, exploring a renewable clean energy has become the top priority. , Hydrogen energy stands out because it is pollution-free, transportable, and easy to store. Hydrogen energy, which is a kind of secondary energy, has become the direction of people’s efforts to extract it from water by using solar energy. , In recent decades, a large number of semiconductor materials have been explored as typical photocatalysts, such as TiO 2 , ZnO, , and g-C 3 N 4 . , For the semiconductor photocatalytic water splitting hydrogen production system, the electrons migrate to the surface of the catalyst in order to reduce H + and release H 2 . At the same time, an outstanding photocatalyst needs to match the band edge position of semiconductor with the redox potential of water, have excellent adsorption to H + , and easily desorb the generated H 2 from the catalyst surface. − Therefore, the selection of efficient semiconductor catalysts is the key factor to improve the catalytic efficiency.…”

The effects of cotton cellulose on both energy band gap of g-C3N4–TiO2 nanoparticles and enhanced photocatalytic properties of cotton-g-C3N4–TiO2 composites

“…This result was due to the adsorption and deposition of the degradation by-products of organic matters during photocatalysis. These deposited carbonaceous substances could form strongly-bound surface complexes on the surface of C-g-C 3 N 4 -TiO 2 cotton fibers and block the active sites of g-C 3 N 4 -TiO 2 nanocomposites (Yang et al 2021). Furthermore, the stability of g-C 3 N 4 -TiO 2 nanocomposites on cotton fiber surfaces before and after the photocatalytic reaction was assessed by EDS quantitative analysis.…”
