Ak. Prabhu et St. Oyama, Development of a hydrogen selective ceramic membrane and its application for the conversion of greenhouse gases, CHEM LETT, (3), 1999, pp. 213-214
A new membrane with 100% selectivity to hydrogen was developed by chemical
vapor deposition of a silica precursor on Vycor glass. Application of the m
odified membrane to the CO2 reforming of CH4 produced conversion levels abo
ve equilibrium.
