摘要
A direct-triblock-copolymer templating method is demonstrated to synthesize ordered mesoporous crystalline C-TiO2 (MCT) composites using phenolic resins and acid-base pairs [acidic TiCl4 and basic counterpart Ti(OC4H7)(4)] as carbon and titanium sources, respectively. The composites possess highly crystalline anatase pore walls that are "glued" by amorphous carbon, ordered mesostructure, high surface areas (similar to 200 m(2)/g), and large pore volumes (similar to 0.15 cm(3)/g). The titania content is as high as 87 wt%. MCT composite favors the immobilization of proteins and enhances the electrocatalytic properties in relation to the reduction of hydrogen peroxide.
