A direct-triblock-copolymer templating method is demonstrated to synthesize ordered mesoporous crystalline C-TiO(2) (MCT) composites using phenolic resins and acid-base pairs [acidic TiCl(4) and basic counterpart Ti(OC(4)H(7))(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 (approximately 200 m(2)/g), and large pore volumes (approximately 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.
一种直接三嵌段共聚物模板法被证明可用于合成有序介孔晶体C-TiO₂（MCT）复合材料，该方法使用酚醛树脂和酸碱对[酸性的TiCl₄和碱性的Ti(OC₄H₇)₄]分别作为碳源和钛源。这些复合材料具有高度结晶的锐钛矿孔壁，它们由无定形碳“胶合”在一起，具有有序的介观结构、高比表面积（约200 m²/g）和大孔体积（约0.15 cm³/g）。二氧化钛含量高达87 wt%。MCT复合材料有利于蛋白质的固定，并增强了与过氧化氢还原相关的电催化性能。
