TiO2 has been investigated for its oxidation capability toward VOCs because of its good photocatalytic activity. However the utilization is limited to UV due to its wider bandgap; furthermore, its fast recombination rate of electron-hole pair reduces the oxidation rate of VOCs. Black-TiO2 and ...
The rate constant of photocatalytic degradation of doxycycline hydrochloride and methylene blue by RGO/BTiO2/2D㈱IFwas determined to be 0.0118 and 0.0232 min1, respectively, which are 2.68 and 3.3 times that of BTiO2. This study could provide deep insight for the design of high and bi‐...
Photo-oxidation of toluene was used as a model reaction to evaluate the photocatalytic performance of black NiO/TiO 2 hybrids under simulated solar light irradiation from a 300W Xe-lamp. The black NiO/TiO 2 hybrids Exhibit 80% of photodegradation conversion and 56% of mineralization efficiency, ...
Furthermore, only O- 2 radicals played an important role in TC photodegradation over white TiO2, whereas both O- 2 and h were responsible for the degradation over black TiO2 and N-doped TiO2. Different from white TiO2 for visible light photocatalytic TC degradation that follows photosensitization...
TiO2 doped with oxygen vacancies is black, and it can be easily formed from conventional white TiO2. Oxygen vacancies in black TiO2 have an analogous effect to other dopants, serving as a promoter of photocatalytic performance. Improvements in the photocatalytic performance of TiO2 have been ...
Since CdS can absorb visible light, of MoS2 can effectively transmit light generated carriers, black TiO2 can improve the photoelectric conversion efficiency, the catalyst exhibits excellent photocatalytic performance decomposition aquatic hydrogen, decomposing hydrogen production speed reaches 4527 umol · h ...
Furthermore, the photocatalytic activity of the black TiO2-x has been evaluated using the degradation of methylene blue under visible light irradiation. 2. Experimental details Starting precursor solutions for the USP were prepared by dissolving titanium (Ⅳ) isopropoxide (TTIP, Ti(C3H7O)4, 99.9...
4/ Photocatalysts: Titanium dioxide has photocatalytic properties, meaning it can facilitate chemical reactions in the presence of light. This property is utilized in applications like self-cleaning surfaces (such as self-cleaning glass) and air and water purification systems.5/ Ceramics and Gla...
