Synthesis of S-doped WO3 nanowires with enhanced photocatalytic performance towards dye degradation

WO3Nanowires on Graphene Sheets as Negative Electrode for Supercapacitors

“…Nanostructured tungsten oxide materials have received increasing attention due to their great potential applications in gas sensors, photocatalysts, field-emission devices, and electrochromic and energy storage devices [1][2][3][4][5][6]. Nanostructured tungsten oxides as electrode materials are expected to display enhanced electrochemical performance because of their large surface area and low charge transport resistance.…”

2D black phosphorus and tungsten trioxide heterojunction for enhancing photocatalytic performance in visible light

“…The binding energy of W 4f 7/2 and W 4f 5/2 were measured at 35.6 eV and 37.7 eV, respectively, which were following the previous reports. 5 The two peaks of both W 4f 7/2 and W 4f 5/2 for WO 3 -BPNs were shied by 0.2 eV towards lower energy compared with those of WO 3 , as presented in Fig. 4a(1) and (2).…”

“…1,2 The photodegradation of organic contaminants under solar radiation using semiconductor materials has been considered as a promising method for treating such pollutants. 3 Many semiconductor materials such as TiO 2 , 4 WO 3 , 5 ZnO, 6 and CdS 7 have been extensively investigated as photocatalysts for degrading organic pollutants under solar radiation. However, the low utilization rate of visible-light and the rapid recombination of photoelectron-hole pairs under photodegradation still inhibit the practical applications of semiconductor photocatalysts in the treatment of organic pollutants.…”

“…1,2 Many investigations have been conducted to overcome these disadvantages and improve the photocatalytic performance, mainly including ion doping and the formation of heterojunction structures between two semiconductor materials. 5,8 Previous studies demonstrated that photocatalytic performance of semiconductor materials was signicantly enhanced due to the doping of non-metal elements N, 9 S, 5 and P, 10 or metal elements Cu, 11 Ag, 12 and Ce. 13 Liang et al proposed that Ag/TiO 2 and Ce/TiO 2 have high photocatalytic degradation performance for formaldehyde gas under UVlight.…”

Extraction and Electrochemical Analysis of Polyphenols in Plant Samples

“…Supercritical is used to refer to the state of matter between gas and liquid; the density and solvability of supercritical fluids are close to those of the liquid, and the viscosity is close to that of the liquid [93][94][95][96][97][98][99][100][101]. The diffusion coefficient is close to that of the gas.…”
