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.
Claims19
A photooxidation catalyst comprising a support and a metallic oxide layer provided on the support,
- wherein the metallic oxide layer has a cross-sectional structure in which a surface region of the metallic oxide layer is more porous than a base region of the metallic oxide layer which is adjacent to the support.
