Preparation of palladium-silver alloy membranes for hydrogen separation by the spray pyrolysis method

Defect‐free palladium membranes on porous stainless‐steel support

“…A spray pyrolysis method was used by Li et al (1993) to deposit a Pd-Ag alloy on the alumina support. Yan et al (1994) and Morooka et al (199.5) formed a thin palladium membrane inside the porous wall of an a-alumina support tube by the metal-organic chemicalCorrespondence concerning this article should be addressed to Y. H. Ma vapor deposition (MOCVD) technique by decomposing palladium (11) acetate in argon under reduced pressure.…”

Chemical vapor deposition of metals: Part 1. An overview of CVD processes

“…A schematic representation of the generalized key steps involved in a CVD process is presented in Figure A Metal-Ce er volatile precursor is transported (1) into the reactor and to the substrate, where it adsorbs (2) and reacts (3) to liberate the supporting ligands, which are subsequently desorbed (6) and transported out of the reactor (7). The metal atoms then diffuse (4) to form a stable nucleus, where subsequent growth occurs ( 5 ) .…”

Thin Film Composite and/or Thin Film Nanocomposite Hollow Fiber Membrane for Water Treatment, Pervaporation and Gas/Vapor Separation

“…The method has been successfully applied for the production of fine metals or metal oxide particles. Li et al [8] obtained a Pd-Ag alloy membrane on the surface of a porous alumina hollow fibre by spray pyrolysis of a Pd(NO 3 ) 2 and AgNO 3 solutions on a H 2 -O 2 flame.…”
