【摘要】 氢氧化铝纳米粒子为模板可以制备中孔炭．改变 pH 值可以调整炭前驱体溶液中氢氧化铝纳米粒子的大小。结果表明：中孔含量随 pH 值的升高而增加；当 pH 值为12时,中孔集中于3～4nm,孔容积为0．108cm~3/g。pH 为8时, 几乎没有中孔生成．更多还原

【Abstract】 The aluminum hydrate could be used as template to synthesis the mesoporous carbon.The nanoparticle size of aluminum hydrate could be adjusted by the pH value in the solution,which contained the aluminum ion and the precursor of carbon.The result showed that the mesopore content increased with the pH value,the mesopore size was concentrated between 3 nm and 4 nm and volume reached 0.108 cm~3/g when the pH of solution was 12;there almost no mesopore formed at the pH of 8.更多还原
