Enhanced photocatalytic activity of Ag₂S particle decorated S-doped WO₃ nanorods synthesized through two-stage vaporous vulcanization processes

Abstract

Ag2S particle decorated S-doped WO3 nanorods formed by vaporous-assisted vulcanization exhibit high photocatalytic activity.

Tuning the heterophase junction in Bi2O3 hybrid crystals with enhanced photocatalytic activity

“…In addition, the holes staying at E VB (2.31 V vs. NHE) for γ-Bi 2 O 3 are more positive than the oxidation potential (2.27 V) of H 2 O/˙OH. 74 In this way, some of them can react with H 2 O molecules to form hydroxyl radicals, and others can efficiently remove organic dye accompanied by other reactive substances, which elucidates that h + occupies the majority to participate in the degradation process towards RhB solution. Simultaneously, the E CB (−0.62 V vs. NHE) of β-Bi 2 O 3 is more negative than the reduction potential (−0.33 V vs. NHE) of O 2 /˙O 2 − , 68 and the CB potential makes the oxygen acquire the electron to combine into the superoxide radical, which possesses strong reducibility.…”

Efficient photocatalytic degradation of ultra-high concentration printing and dyeing wastewater using a SiO2/GCN nanocomposite

“…Visible light catalysts such as ZnO, 15,16 BiVO 4 , 17,18 TiO 2 , [19][20][21] rGO, 22,23 and WO 3 , 24,25 have demonstrated impressive properties. However, these materials are typically expensive to produce due to their reliance on significant quantities of metals or complex synthesis processes.…”
