摘要
采用磁力搅拌法和水浴振荡法制备应用于甲酸分解的Pd/活性炭(AC)催化剂,研究了活性炭载体改性和制备方法对催化剂分解甲酸性能的影响。采用恒温水浴振荡装置,在80℃水浴中进行甲酸催化分解反应,以甲酸的催化分解率评价催化剂催化活性。结果表明,以经过不同的酸、碱、盐溶液改性后的活性炭为载体采用不同方法制备的Pd/AC催化剂对甲酸的催化分解效果不同,以Na2CO3改性的活性炭为载体采用磁力搅拌法制备的催化剂活性最好,甲酸水溶液的分解率达85%以上,含甲酸的工业废水的分解率达70%。
Electromagnetic stirring and oscillation bath were used to prepare Pd/（activated carbon） catalyst for the decomposition of formic acid, and the effects of activated carbon modification and preparation methods to catalytic activity were investigated. Using thermostatic water oscillation device, the activity of catalyst was evaluated at 80 ℃ by the rate of formic acid decomposition. Results showed that Pd/AC catalysts prepared from activated carbon modified with different acid, alkali and salt solutions have different activity for the decomposition of formic acid. Pd/AC catalyst prepared from activated carbon modified with Na2CO3 solution under electromagnetic stirring shows the highest catalytic activity with decomposition of higher than 85% for formic acid aqueous solution and higher than 70% for the formic acid in industrial wastewater.
