Photocatalytic activity of N-TiO2/O-doped N vacancy g-C3N4 and the intermediates toxicity evaluation under tetracycline hydrochloride and Cr(VI) coexistence environment

Engineering a Rapid Charge Transfer Pathway for Enhanced Photocatalytic Removal Efficiency of Hexavalent Chromium over C3N4/NH2–UIO‐66 Compounds

“…The peaks centered around 577.3 and 578.2 eV are attributed to the 2p 3/2 and 2p 1/2 of the +3 valence state of Cr. [ 52,55,56 ] The Cr(III) species deposited over the CN surfaces could inhibit the light harvester and the photoexcited electron transfer from CN to Zr clusters, which led to a tiny decrease in the photocatalytic activity after the five times recycling performance.…”

Antimicrobial TiO2 nanocomposite coatings for surfaces, dental and orthopaedic implants

“…The deficiency of nanoparticles from the coating surface was also confirmed by X-ray fluorescence (XRF) analysis, where the existence of Ti was reduced over the period. These results suggest that the influence of environmental factors on the activity of TiO 2 must be addressed for the sustainability of coatings in real-life applications [55] , [56] , [57] .…”

A three-dimensional nano-network WO3/F-TiO2-{001} heterojunction constructed with OH-TiOF2 as the precursor and its efficient degradation of methylene blue

“…[11][12][13][14] However, TiO 2 has a wide band gap of 3.0-3.2 eV, which causes it to respond only under ultraviolet radiation, and its photocarriers recombine rapidly, which seriously hinders its application and development in practice. 15,16 In order to solve this problem, many researchers used metal doping, [17][18][19] nonmetal doping, 20 precious metal deposition, 21,22 etc. The introduction of dopants can effectively reduce the band gap width of TiO 2 , which makes TiO 2 absorb in the visible region, and increases the internal electron acceptor, thus slowing down the carrier recombination rate.…”
