Photocatalysis has emerged as a promising technology for the removal of emerging contaminants such antibiotics from water. Fixing photocatalytic materials on polymers to prepare applicable membranes is feasible method applying photocatalysis. This study explored preparation composite PAN-TiO2 and PAN-TiO2-rGO (PAN-rGTi) by combining TiO2, TiO2-reduced graphene oxide (rGO) polyacrylonitrile (PAN) using electrospinning. Characterization through SEM EDS analysis confirms membrane’s...

Main observation and conclusion The design of high‐efficiency non‐noble earth‐abundant electrocatalysts for hydrogen evolution reaction (HER) is highly paramount water splitting renewable energy systems. Molybdenum disulfide (MoS 2 ) with abundant edge sites can be utilized as a promising alternative, but its catalytic activity greatly related to the pH values, especially in an alkaline environment due extremely high barriers adsorption dissociation steps. Here we report exceptionally...
In this paper, graphene/multi-walled carbon nanotubes (GM) hybrid nanostructure was synthesized by modifying GR using salicylamide. Cu -doped ZnO nanoparticles were successfully decorated on GR/MWNTs hybrids (GM). Their photocatalytic performance for the degradation of methyl orange (MO) investigated and results showed that synthetic GM/ exhibited better ability than MWNTs/ GR/ hybrids, in which degraded rate 20 mg/L MO solution reaches about 100% 45 min.
A method for suppressing impurities in GaN thin films grown via plasma-enhanced atomic deposition (PEALD) through the situ pretreatment of Si (100) substrate with plasma was developed. This approach leads to a superior GaN/Si interface. After pretreatment, thickness interfacial layer between and substrates decreases from 2.0 1.6 nm, oxygen impurity content at interface reduces 34 12%. The pretreated exhibit thinner amorphous transition 5.3 nm comparison those nonpretreated 18.0 which...
The growth of high-quality epitaxial gallium nitride (GaN) thin films is achieved by using a baking and plasma pretreatment the substrate prior to GaN plasma-enhanced atomic layer deposition (PE-ALD). It found that such makes grow coherently on sapphire substrates, following layer-by-layer mechanism. deposited film shows high crystalline quality, sharp GaN/sapphire interface, flat surface. possibility growing epilayers in this way broadens range applications for PE-ALD GaN-based devices.
Negative photoconductivity effect has been observed in the Au/WO3 nanowire/Au devices a high humidity environment, which might be attributed to accumulation of H+ ions on surface WO3 nanowire. Under illumination with violet light (445 nm), photo-excited holes can oxidize adsorbed H2O molecules produce and O2, while electrons at conduction band bottom do not have enough energy reduce ions. These will accumulate hexagonalWO3 They capture mobile then concentration carriers, result significant...
A simple and versatile approach decorated TiO 2 nanoparticles on the surface of multi-walled carbon nanotube (MWNTs) was reported. MWNTs can be continuously coated by layer anatase with thickness about 20 nm assistance salicylamide. Moreover, size 10 are uniformly deposited using microwave radiation. The synthetic MWNTs/ hybrids have been proven to very high photocatalytic ability for methyl orange (MO) without any additional treatment.
Metal ion-induced water pollution is attracting increasing public attention. Perovskite quantum dots and metal-organic frameworks (MOFs), owing to their outstanding properties, hold promise as ideal probes for detecting metal ions.
