Gas permeation redox effect on binary lanthanum cobalt silica membranes with enhanced silicate formation

Tailoring the structure and gas permeation properties of silica membranes via binary metal oxides doping

The incorporation of binary Co–Mn or Co–Cr oxides within the silica matrix leads to the formation of silica structures with different networks, which allows tuning of the gas separation properties.

Redox structural control of Pd and PdO silica matrices

Pd crystallite sizes within silica were controlled by calcination in either oxidation or reduction conditions. Control was imparted by the temperature of decomposition of the PdCl₂ precursor, and thus the degree of condensation of the silica matrix.
