Nanostructured Palladium-Doped Silica Membrane Layer Synthesis for Hydrogen Separation: Effect of Activated Sublayers
Palladium doped silica membranes were synthesized by the sol-gel method using two different procedures. The first palladium-doped silica membrane (M1) was synthesized with a coating of four layers of silica-palladium sol. The second membrane (M2) was synthesized with a coating of two silica layers followed by a coating of two silica-palladium layers. Scanning electron microscopy (SEM) proved th...
متن کاملSynthesis and Performance of Nanostructure Templated Silica Membranes Surface-modified by Two Different Procedures
Uncontrolled population growth and increased consumption of fossil fuels have led to the emission of pollutants and greenhouse gases. This is mostly a concern for reducing emissions of greenhouse gases, such as carbon dioxide because of its impact on global climate change1,2. The presence of carbon dioxide in the natural gas mixture can lead to lower heating value of gas, corrosion of processin...
متن کاملTemplate-free synthesis of silica ellipsoids.
We have created ellipsoidal or spherical morphologies of silica particles in a template-free scheme that involves controlling surface tension forces through selected volume ratios of a water/oil micellar system.
متن کاملSynthesis of a Multilayer Ceramic Membrane Used for Hydrogen Separation at High Temperature
A multilayer composite ceramic membrane was prepared by depositing a nano-scale layer of SiO2 on top of a modified porous alumina support by chemical vapor deposition (CVD) method. The modification of the support was carried out by adding a graded layer of Al2O3 (γ-alumina phase), using sol-gel method. An optimized temperature of 700 K for intermediate layer calcination was gained by XRD analys...
متن کاملPolyamide Forward Osmosis Membrane: Synthesis, Characterization and Its Performance for Humic Acid Removal
In this research, modification on the ultrafiltration (UF) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (FO) water treatment. Two monomers, m-Phenylenediamine (MPD) and Trimesoyl chloride (TMC) with different concentrations of MPD (2.0% w/v and 1.0% w/v) were reacted with TMC (0.15% w/v) for interfacial polymerization (...
