摘　　要：研究了双金属催化剂体系催化过氧化氢分解反应,测量了不同催化剂体系的活化能.结果表明,双金属催化剂对过氧化氢分解反应具有良好的催化性能,且双金属催化剂存在协同催化作用;而酸性环境对过氧化氢催化分解有明显的抑制作用.The decomposition reaction of hydrogen peroxide catalyzed by dual-metal catalyst systems was investigated,and the activation energy for various catalyst systems was measured.Results show that dual-metal catalysts have good catalytic performance for the decomposition reaction of hydrogen peroxide,and there exists synergistic catalytic function for the dual-metal catalyst systems.However,acidic environment significantly retarded the catalyzed decomposition of hydrogen peroxide.
