摘要： The invention relates to a process to produce catalysts by powder injection moulding and the catalysts thereof, wherein the catalysts are made by preparing a ceramic formulation with temperature controlled rheological properties comprising catalytic components, heating the powder formulation up to at least the fluid state transition temperature, shaping a sample by injecting the fluid powder formulation into an injection mould followed by cooling the injected powder formulation below the fluid state transition temperature, de-binding the shaped sample, and sintering the shaped sample to form a ceramic catalyst. Alternatively the ceramic structure may be formed initially followed by a coating of the ceramic structure by one or more catalytic compounds.
