Abstract
The present invention refers to titanium oxide microspheres having photocatalytic properties which can, for example, be used in a method for cleaning wastewater which uses a submerged membrane reactor.
Claims17
A method of manufacturing a titanium oxide microsphere having photocatalytic property and having a size of about 10 μm to about 200 μm and a mesoporous structure with a pore size in a range of about 2 to about 50 nm, wherein said method comprises:
- preparing a sol by mixing an organometallic titanium precursor with an alcohol without adding H2O;
- aging said sol;
- mixing said aged sol with titanium oxide powder;
- spraying said mixture to form said titanium oxide photocatalyst microspheres;
- and
- calcining said microspheres.
