Abstract: A method of treating a ceramic body in a glass making process includes delivering a molten glass to a heated ceramic body, the ceramic body including a ceramic phase and an intergranular glass phase, the molten glass being in contact with a surface of the ceramic body. The method further includes contacting the ceramic body with a first electrode and contacting the molten glass with a second electrode. The method further includes applying an electric field between the first electrode and the second electrode to create an electric potential difference across the ceramic body between the first and second electrodes, the electric potential difference being less than an electrolysis threshold of the ceramic phase and the intergranular glass phase. The intergranular glass phase demixes under driven diffusion in the applied electric field and mobile cations in the intergranular glass phase enrich proximate one of the first and second electrode.

Abstract: Direct epoxidation of propene is carried out on electrochemically tuned mixed oxide catalyst surfaces in a single chamber reactor with mixed reaction gas of hydrocarbon and oxygen. Yield and selectivity improvement compared to platinum- or silver-based noble metal catalysts have been demonstrated for the same reactor set up. Increase in propylene oxide yield has been demonstrated when a cell voltage is applied.
