Forward osmosis membranes have a wide range of applications in the field water treatment. However, application seawater desalination is restricted, so research forward for poses new challenges. In this study, zeolitic imidazolate framework-8 (ZIF-8) was synthesized by mechanical stirring method, and its crystal structure, surface morphology, functional group characteristics, thermochemical stability, pore size distribution specific area were analyzed. The cellulose acetate (CA)/ZIF-8 mixed...
Hexavalent chromium is one of the main heavy metal pollutants. As environmental legislation becomes increasingly strict, seeking new technology to treat wastewater containing hexavalent becoming more and important. In this research, a novel modified ultrafiltration membrane that could be applied adsorb purify water chromium, was prepared by polyvinylidene fluoride (PVDF) blending with 2-aminobenzothiazole via phase inversion. The performance characterized evaluation instrument performance,...
We have investigated the role of hydrogen plasma pretreatment in promoting silicon surface passivation, particular examining its effects on modifying microstructure subsequently deposited thin hydrogenated amorphous (a-Si:H) passivation film. demonstrate that pretreating with for 40 s improves homogeneity and compactness a-Si:H film by enhancing precursor diffusion thus increasing minority carrier lifetime (τ(eff)). However, excessive also increases density dangling bond defects due to...
In this study, nanosheet g-C3N4-H2 was prepared by thermal exfoliation of bulk g-C3N4 under hydrogen. A series Ru/g-C3N4-H2 catalysts with Ru species supported on the were synthesized via ultrasonic assisted impregnation-deposition method. Ultrafine nanoparticles (<2 nm) highly dispersed g-C3N4-H2. Strong interaction due to Ru-Nx coordination facilitated uniform distribution species. Meanwhile, involvement surface basicity derived from abundant nitrogen sites favourable for enhancing...
The redox pretreatment of samples is one the crucial ways altering catalytic properties supported noble metal materials in many heterogeneous reactions. Here, H2-reducing reported to enhance thermal stability Au-CeO2 catalysts prepared by deposition–precipitation method and calcination at 600 °C for CO oxidation. In order understand improved activity stability, a series techniques were used characterize physico-chemical changes catalyst samples. H2 may lead to: (i) strong metal–support...
Nanocrystalline La 2 Sn O 7 and 1.8 Co 0.2 with a phase‐pure pyrochlore structure were synthesized by hydrothermal method, their catalytic activity was investigated for soot combustion. The as‐synthesized catalysts presented relatively larger surface area, pore volume, which benefit to the gas molecule diffusion in reaction. A uniform spherical particle size of 200–500 nm found SEM. samples via route are more active combustion, ascribing morphology, high area improved oxygen mobility. After...
NOx storage-reduction (NSR) is a potential approach for the effective removal of under lean conditions in lean-burn engines. Herein, manganese-doped mixed oxides (Mn/MgAlOx) with high performance low temperature storage and release were derived from hydrotalcites precursors prepared by facile coprecipitation method.
