“…With industrialization, the degradation and decolorization of dye-contaminated wastewater is becoming increasingly difficult to treat [1][2][3][4][5]. Using free and green solar energy, semiconductor-based photocatalysis has been recognized as one of the most promising and sustainable ways in environmental remediation to purify polluted water [6][7][8][9].…”

TiO 2 nanofiber film (TiO 2 NFF) with visible light scattering ability was successfully synthesized by an ethylene glycol-assisted hydrothermal method, Au nanoparticles (Au NPs) were then deposited on the surface of TiO 2 film using microwave-assisted chemical reduction process, and at last, Bi 2 MoO 6 /Au/TiO 2 ternary photocatalytic film was successfully synthesized via a simple alcohol-thermal method using Au/TiO 2 nanofilms as templates. The photocatalytic activities of as-fabricated samples were investigated by the oxidation of organic pollutants, like methylene blue (MB) and phenol, and the reduction of aqueous Cr(VI) under visible light. It shows that the Bi 2 MoO 6 /Au/TiO 2 composite displays a much higher visible-light-responsive photocatalytic performance compared to pure TiO 2 , Au/TiO 2 NFF, and Bi 2 MoO 6 /TiO 2 complex. The improved visible light photoactivity could be ascribed to the excellent light scattering structure of TiO 2 NFF, the surface plasmon resonance effect of Au NPs, and the highly effective separation of photogenerated electrons and holes through the Z-scheme Bi 2 MoO 6 /Au/TiO 2 system, in which Au NPs plays a key role in transmitting charges in the photocatalytic process. Keywords: Bi 2 MoO 6 /Au/TiO 2 , light scattering, nano-fiber film, photogenerated electrons

“…Because it is a simple process and has wide applications, non‐thermal plasma (NTP) is regarded as the most promising technology for VOCs removal . Non‐thermal plasma exhibits high VOCs removal efficiency but low product selectivity . By combining non‐thermal plasma with catalytic technology (PC), the directed transformation of reactants is promoted and improves product selectivity .…”

BACKGROUND: To find an appropriate catalyst in the adsorption plasma catalytic process, degradation of toluene over 13X zeolite supported catalysts were studied. RESULTS: 13X zeolite exhibited excellent toluene adsorption capacity but weak catalytic ability. After loading Cu, Co, Ce and Mg active compounds by the impregnation method, adsorption capacity was reduced and catalytic performance was significantly improved. Co/13X exhibited good adsorption capacity and excellent catalytic performance, which carbon balance was 81.6% with 74.4% of CO x for toluene adsorption capacity of 0.51 mmol. The effect of cobalt loading and calcination temperature on Co/13X for toluene degradation were studied, and it was found that 5% and 500 ∘ C were the optimum loading value and calcination temperature. The characterization results of BET, FTIR, XRD, XPS and SEM were correlated with catalyst performance. CONCLUSIONS: The active compounds block the pores and reduce the specific surface area of 13X zeolite, but active sites of catalysts can decompose ozone to produce more atomic oxygen species. Co 3+ could form -complexation bonding with toluene and Co 3 O 4 is a P-type semiconductor, which has large oxygen adsorption capacity and converts oxygen into O − and O 2− easily. Co 3 O 4 present in Co/13X is the active point for toluene degradation by adsorption and plasma catalytic activity.

BACKGROUND Semiconductor photocatalysis is the most promising green and energy‐saving technology for environmental remediation. Unfortunately, photocatalysis nanotechnology for its practical application is often challenged by the low capturing ability for visible light and use of expensive noble metals. In this work, we report the non‐noble Bi nanoparticles assembled on Bi2WO6 with enhanced visible‐light photocatalytic activity for decontamination of phenol and hexavalent chromium in water. RESULTS The 3% Bi/Bi2WO6 composite had the highest photocatalytic activity compared to pristine Bi2WO6, which could completely decompose phenol into small products within 120 min. More importantly, the Cr(VI) removal rate of the 3% Bi/Bi2WO6 catalyst in the presence of triethanolamine (TEOA, 2%) after irradiation for 12 min was up to 96.2%. CONCLUSIONS The improved photocatalytic performance could be due to the fast transfer of photogenerated charge carried by the formation of an anti‐barrier layer at the interface between metal Bi nanoparticles and the n‐type Bi2WO6 semiconductor; the enhancement of electron energy may be attributed to the localized surface plasmon resonance properties of Bi nanoparticles, as well as conspicuously strengthened and broad light‐capturing ability across the whole visible‐light range. This strategy could provide some inspiration for the design of other Bi‐based semiconductor heterostructures for decomposing harmful organic pollutants in wastewater and purifying hazardous gases in the air. © 2018 Society of Chemical Industry
