Abstract
A photocatalyst and a manufacturing method therefore, in which the adhesion to a support is increased and a baking step is simplified. The photocatalyst comprises the support and a metallic oxide layer provided on the support by applying and baking a colloidal solution including at least a metallic oxide precursor on the support, wherein the metallic oxide layer includes a high density metallic oxide layer of a less porous structure and a low density metallic oxide layer of a more porous structure.
Claims15
A manufacturing method of a photooxidation catalyst, comprising applying a first colloidal solution comprising a first metallic oxide precursor onto a support while baking the first colloidal solution applied onto the support to form a metallic oxide layer.
A manufacturing method of a photooxidation catalyst, comprising the steps of:
- producing a gel from a mixed solution including at least one metallic compound;
- hydrolyzing and dehydrocondensing the metallic compound in the gel to produce a colloidal solution comprising a metallic oxide precursor;
- and
- applying the colloidal solution onto a support while baking the colloidal solution applied onto the support to form a metallic oxide layer.
A manufacturing method of a photooxidation catalyst, comprising the steps of:
- heating a support;
- applying a first colloidal solution comprising at least one metallic oxide precursor and a solvent onto the support while heating the support;
- and
- removing the solvent from the first colloidal solution to form a first metallic oxide layer on the support.
