title: Tuning the pore sizes of novel silica membranes for improved gas permeation properties via an in situ reaction between NH3 and Si-H groups.
abstract: A new concept was proposed to control the pore size in a novel silica membrane. The tuning of the pore sizes in triethoxysilane (TRIES)-derived membranes was successfully conducted via an in situ reaction between NH3 and Si-H groups at high temperatures. The formation of Si-NH2 and/or Si-NH groups in the silica structure enhanced the hydrogen selectivity.
