A method for manufacturing a catalyst support, includes, in the following order, the steps of: (a) shaping a non-sintered porous ceramic base support; (b) depositing, on at least part of the surface of the non-sintered porous ceramic base support, a suspension of ceramic powder in a solvent or a mixture of solvents so as to form an interface layer able to increase the surface area of the base support; (c) sintering the base support, at least partially coated with the suspension. This method allows to economically and rapidly manufacture catalyst supports, and especially burners for fragrance diffuser.
A method for manufacturing a catalyst support, comprising, in the following order, the steps of:
A method according to claim 1, wherein a porous ceramic with a sintering temperature lower than 1100° C. is selected.
A method according to claim 1, wherein a porous ceramic with a porosity between 30 and 70% is selected.
A method according to claim 1, wherein the suspension further comprises between 15 wt % and 30 wt % of ceramic powder.
A method according to claim 1, wherein the ceramic powder has a surface area higher than 5 m2/g.
A method according to claim 1, wherein the ceramic powder is based on a material selected from the group consisting of spinel, alumina, perovskite, zirconia, apatite-type ceramics such as hydroxyapatite, titanium dioxide and mixtures thereof.
A method according to claim 1, wherein the at least one solvent is selected from the group consisting of water, organic solvents and mixtures thereof.
A method according to claim 1, wherein the suspension comprises a dispersing agent,
A method according to claim 1, wherein the suspension comprises a binder.
A method according to claim 1, wherein sintering is carried out at a temperature lower than 1100° C.
A method according to claim 1, wherein the method comprises, after step (c), a step (d) comprising depositing at least one catalyst on at least part of the interface layer.
