Experimental investigation of the transport mechanism of several gases during the CVD post-treatment of nanoporous membranes

•Ceramic membranes were modified by applying a cyclic mode of CVD process.•a-Alumina/silica tubes with a separation layer of 1nm pore size were used as substrates.•The substrates’ pore structure evolution during the CVD processes was investigated.•The permeance of He and N2 gases with the progress o...
