Photothermal synergic enhancement of direct Z-scheme behavior of Bi4TaO8Cl/W18O49 heterostructure for CO2 reduction
Jingyu Yan,Changhua Wang,He Ma,Yingying Li,Yichun Liu,Norihiro Suzuki,Chiaki Terashima,Akira Fujishima,Xintong Zhang +8 more
TL;DR: In this paper, the photocatalytic reduction of CO2 over the direct Bi4TaO8Cl/W18O49 (BiW) Z-scheme system, which is assembled from Bi 4TaO 8Cl nanosheet and nanosized W18O 49, is shown to be markedly enhanced by simple integration of the photocatinalytic process with external heating.

Fei Yu,Changhua Wang,Yingying Li,He Ma,Rui Wang,Yichun Liu,Norihiro Suzuki,Chiaki Terashima,Bunsho Ohtani,Tsuyoshi Ochiai,Akira Fujishima,Xintong Zhang +11 more
TL;DR: The SPP‐treated TiO2 exhibits a 300 times higher conversion rate for CO2 reduction under solar light irradiation and a 7.5 times higher removal rate of acetaldehyde under UV light irradation, suggesting the effectiveness of the proposed strategy to enhance the photoactivity of colored wide‐bandgap oxides for energy and environmental applications.

High-humidity tolerance of porous TiO2(B) microspheres in photothermal catalytic removal of NOx
TL;DR: In this paper, the P25 TiO2 photocatalyst showed a significant decrease in non-NO2 selectivity from 95.02% to 58.33% when RH increases from 20% to 80%.
