Carbon-coated catalytic membranes for gas/liquid catalytic membrane reactors

Procedures have been optimised for coating a thin carbon layer on a multilayer alpha-alumina macroporous tubular-type membrane as well as to deposit a thin microporous carbon layer inside the pores of the ceramic membrane.

Work in the second half of the project demonstrated that the performance of the carbon membrane layer was strongly dependent on the degree of cure of the resin precursor achieved through thermal ageing of the resin solution. Following detailed optimisation of the resin precursor the as deposited thin (~1-3micron) surface carbon layer is an excellent gas separation membrane and has shown interesting separating properties for H2/N2 with potential in a wide range of other gas separations.

Activation of the carbon layer is necessary to provide sufficient porosity to support the palladium catalyst for the generation of the hdyrogen peroxide. The carbon deposition and activation procedure has been optimised to provide the required catalyst loading and activity.

The carbon-modified ceramic membranes can be used as versatile starting materials for preparation of catalytic membranes with different types of active metals for various applications.
