Fibrous silica ZSM-5 (FZSM-5) with a novel dendrimeric morphology was synthesized using CTAB-based microemulsion system. The dendrimers increased the active site accessibility and enhanced catalytic activity for large molecule hydrocracking ethylbenzene dehydrogenation.
Currently, energy demand is growing swiftly with global economic growth. The combustion of fossil fuels one the major environmental threats due to release CO 2 into atmosphere. Reducing greenhouse gases most critical challenges facing society today. It has been proposed that converting and valuable chemicals such as methanol for reducing gas emissions can be a favorable solution. This review describes recent development synthesis from mechanistic point view. Several reaction pathways...
The rapid and continuous depletion of fossil-based resources has boosted extensive research on alternative energy from renewable resources. In this sense, heterogeneous catalysts play an inevitable role in converting into fuels. performance strictly depends their structures physicochemical properties. As a rule thumb, with large specific surface areas possess more catalytic sites to enhance the overall performance. Nanoporous materials have emerged as highly active due internal area,...
Dye-induced water pollution is a noteworthy environmental issue, mainly caused by industrial activities that utilize and release effluent-containing dyes, especially azo dyes. One frequently employed large-scale technique for removing dyes from photocatalysis degradation. The use of MXene-based catalysts as an advanced material holds promise in overcoming the limitations inherent previous due to its expansive surface area unique tunable properties. potential integrating with nanoparticles...
Gallium nitride (GaN) film delamination is an important process during the fabrication of GaN light-emitting diodes (LEDs) and laser diodes. Here, we utilize 520 nm femtosecond pulses, exploiting nonlinear absorption rather than single-photon such as in conventional lift-off (LLO) employing excimer or Q-switched sources. The focus this study to investigate influence scanning speed integrated fluence corresponding energy per area LLO processing LED chips their resulting structural properties....
Recently, zeolites with two-dimensional structures, so-called nanosheet zeolites, have been intensively advanced owing to their excellent catalytic performance compared conventional zeolite. This extremely thin structure of zeolite provides more accessible active sites contributing shortened diffusion pathways and primarily enables bulky molecules undergo reactions. Several such as MFI, FAU, MOR, MWW, TS-1, successfully synthesized. Generally, they are obtained by direct synthesis method...
The generation of mesoporosity in SSZ-13 zeolite by means desilication via post alkaline treatment normally results severe damage to the microporous framework hence giving an undesirable decline catalytic performance. Herein, we propose a post-synthetic that is controllable with aim preserve high crystallinity during formation mesopores. extent media controlled deliberately leaving organics within frameworks as they can effectively hinder attack hydroxyl ions on siloxane bonds. resulting...
The solvent-free, seed-directed synthesis using natural precursors has emerged as a sustainable route for the of zeolite. Albeit significant progress in techniques, crystallization behaviors zeolites are somewhat elusive. Herein, we performed detailed investigation ZSM-5 synthesized through rice husk silica starting materials. at 180 °C is completed rapidly 10 h, with an ultrahigh zeolite yield least 95%. Moreover, evaluated kinetics different temperatures nonlinear Avrami equation and found...
Trade-off issue and membrane fouling remain two major issues in the utilization of technology for water treatment due to reduced permeability lifetime. In our study, we employed 3-aminopropyltriethoxysilane modified bentonite (BNTAPS) as an anti-fouling modifier prepare polyvinylidene fluoride (PVDF)-based membranes via phase inversion method. The effects BNTAPS concentration on physical, mechanical, morphological, filtration performance hybrid have been investigated. It was found that...
The zinc oxide nanotube functionalized by Ti3C2Tx (ZnO NT/MXene) has been successfully prepared. MXene layer was attached to the ZnO NT surface simply dipping method. prepared material confirmed several characterization techniques. By modifying with MXene, a decrease in bandgap value and an increase photoelectrochemical (PEC) performance observed. current density of NT/MXene about 0.2 mA/cm2 (1.4 V vs Ag/AgCl), which is two times higher than NT. Furthermore, oxygen evolution modified noted...
