Interfacial Charge Transfers of Surface‐Modified TiO₂Nanoparticles in Photocatalytic Water Treatment

Deactivation-Tolerance of Heterojunction Anatase and Bronze TiO2 in the Photocatalytic Mineralization of Toluene

“…13−18 Representatively, a combination of anatase (A) and rutile (R) phases (AR-TiO 2 or AR) is readily achieved via the calcination of anatase TiO 2 . 6 Recently, another heterojunction of anatase (A) and bronze (B) phase TiO 2 (AB-TiO 2 or AB) has received increasing attention. Bronze TiO 2 (B-TiO 2 ) with a monoclinic phase (C2/m) has a layered titanate structure (M x TiO 2 , where M = Li + , Na + , K + , etc.).…”

“…The extensive use of synthetic building materials, electronics, and household products causes severe indoor air pollution by releasing various volatile organic compounds (VOCs), such as acetaldehyde (CH 3 CHO) and toluene (C 7 H 8 ). , VOCs are responsible for sick building syndrome and multiple chemical sensitivities, causing several health issues (e.g., headaches, allergies, and nausea) . Among the existing indoor air purification technologies, photocatalysis is considered the most appropriate because of its operation under room temperature and atmospheric pressure without any auxiliary chemicals (e.g., O 3 and H 2 O 2 ) or expensive elements, and because it mineralizes pollutants into H 2 O and CO 2 by in situ generated hydroxyl radicals ( · OH). − …”

“…To address the above challenge, various heterojunction structures have been designed to improve charge separation and consequently photocatalytic activity. − Representatively, a combination of anatase (A) and rutile (R) phases (AR-TiO 2 or AR) is readily achieved via the calcination of anatase TiO 2 .
