Synthesis of ordered mesoporous crystalline carbon–anatase composites with high titania contents

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 (∼200 m2/g), and large pore volumes (∼0.15 cm3/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.

Mesoporous crystalline C-TiO2 composites have been synthesized via the combination of the organic–organic self-assembly and the “acid–base pairs” route. The anatase content can reach 87 wt%.Figure optionsDownload as PowerPoint slide
