[0045] The present invention provides a method for preparing a coconut shell charcoal titanium dioxide, comprising the steps of:
[0046] S1, precursor configuration: mix the titanium-containing compound, water, solvent, mix well, formulate titanium dioxide solution or sol, to obtain a titanium dioxide precursor;
[0047] S2, Coconut Shell Material Preparation: Clear the surface of the coconut shell and the chopped flesh, cut the dense shell portion into a block, clean, dried to obtain a coconut material;
[0048] S3, soaking: adding the coconut shell material into the titanium dioxide precursor liquid, soaking, drying, drying to obtain a dry material;
[0049] S4, once carbonization: placed the drying material in the carbonization furnace, passed through high temperature carbonization, resulting in a carbonized material;
[0050] S5, powdering: pulverizing the carbonized material, sieve, take the carbonized material between 100 to 200 mesh, to obtain a powder;
[0051] S6, kneadi...
