| 摘 要： | 高效、清洁且无毒无害的催化剂是实现以甲酸(HCOOH)为化学储氢材料分解制氢的重点。本文采用水热法在453K的条件下制备TiO2载体,再通过浸渍法向其中加入总量为0.1 mmol的NiCl2.6H2O和K2PdCl4金属溶液,将活性组分Ni、Pd负载到TiO2载体上合成NiPd/TiO2催化剂,并探究其对催化甲酸分解制氢的性能的影响。探究结果表明,在光照条件下,NiPd/TiO2催化剂中,当金属Ni:Pd比例为2:8时,催化剂的反应转化频率(TOF)值最大,此时催化剂的 TOF 为3528 h-1,且该催化剂上甲酸分解的活化能(Ea)为53.9 kJ/mol。关键词：镍钯催化剂；甲酸；分解制氢；二氧化钛；光照中图分类号：TQ630 文献标识码： A 文章编号：

| Abstract: | Efficient, clean and non-toxic and non-hazardous catalysts are the focus to realize the decomposition of formic acid (HCOOH) as chemical hydrogen storage material for hydrogen production. In this paper, TiO2 carriers were prepared by hydrothermal method at 453 K, and then NiCl2.6H2O and K2PdCl4 metal solutions with a total amount of 0.1 mmol were added to them by impregnation method to synthesize NiPd/TiO2 catalysts by loading the active components Ni and Pd onto TiO2 carriers, and to investigate their effects on the performance of catalytic formic acid decomposition for hydrogen production. The results of the investigation showed that the reaction conversion frequency (TOF) value of the NiPd/TiO2 catalyst was the largest when the metal Ni:Pd ratio was 2:8 under the catalysis of light, at which the TOF of the catalyst was 3528 h-1, and the activation energy (Ea) of formic acid decomposition on this catalyst was 53.9 kJ/mol. |
