Preparation of palladium/NaX/PSS membrane for hydrogen separation

Pt-based structured catalysts on metallic supports synthesized by electroless plating deposition for toluene complete oxidation

“…The electroless coating process has gained wide acceptance in the market due to the coatings' excellent corrosion and wear resistance properties [25,26]. Recently electroless nickel nanosheets on carbonaceous materials as supercapacitor electrode [27,28], and electroless palladium nano-scale layers on porous materials for hydrogen membrane separation [29,30] Ultrasonic vibration test Bending fastness test Tearing fastness test 200 no weight loss no surface cracking no surface peeling 350 no weight loss no surface cracking no surface peeling 450 no weight loss no surface cracking no surface peeling 600 no weight loss no surface cracking slight surface peeling metallic structured substrate was achieved by using this new technique of EPD. The as-obtained structured catalysts were analyzed by several characterization methods and adhesion strength tests to reveal their chemical and physical properties.…”

Effects of different silica intermediate layers for hydrogen diffusion enhancement of palladium membranes applied to porous stainless steel support

“…The introduction of non-metallic intermediate layers can prevent intermetallic diffusion and smooth the surface of the supports. NaA zeolite 5 , NaX zeolite 6 , and siliceous materials 7 were selected as the intermediate layer. The H 2 permeance of a Pd membrane over a porous SUS tube with a non-metallic barrier, however, was insufficient for applications to membrane systems in hydrogen separation.…”
