Loaded light catalyst and preparation thereof

The invention provides a loaded light catalyst which comprises a cotton matrix and a light catalyst loaded to the cotton matrix. The light catalyst is loaded to the cotton matrix through a Linker reagent. The cotton contains a surface active group R1, the light catalyst is an organic light catalyst or a metal complex light catalyst, and the light catalyst contains an active group R2; and the Linker reagent at least contains a first active functional group R3 capable of being combined with the surface active group R1 and a second active functional group R4 capable of being combined with the active group R2. 本发明提供了种负载型光催化剂，所述负载型光催化剂包括棉花基体，以及负载在所述棉花基体上的光催化剂，且所述光催化剂通过Linker试剂负载在所述棉花基体上，其中，所述棉花含有表面活性基团R1；所述光催化剂为有机光催化剂或金属配合物光催化剂，且所述光催化剂含有活性基团R2；所述Linker试剂至少含有能与所述表面活性基团R1结合的第活性官能团R3和能与所述活性基团R2结合的第二活性官能团R4。
