Evaluations of Hydrogen Permeation on γ-Al_2O_3 Synthesized by Sol-Gel Process

摘要

The purpose of this work was hydrogen permeation of ceramic or metal/ceramic membrane using γ-Al_2O_3 by synthesizing. The γ-Al_2O_3 was synthesized by using the sol-gel process with aluminum isopropoxide and primary distilled water as the precursor and solvent. The γ-Al_2O_3-based membranes were prepared using HPS. The phase transformation, thermal evolution, surface are and morphology of γ-Al_2O_3 and γ-Al_2O_3-based membranes were characterized by XRD, TG-DTA. BET and FE-SEM. The hydrogen permeation of γ-Al_2O_3-based membranes was examined at room temperature comparing with other paper using nickel composited membrane on alumina ceramic support.
