200–250 °C as a self-propagating rapid redox process accompanied with the release of multiple gases. The decomposition leads to formation of sponge-like silver having hierarchical open pore system with pore size spanning from 10 µm to 10 nm. The as-obtained silver sponges exhibited favorable activity toward H 2 O 2 electrochemical reduction, making them potentially interesting as non-enzyme hydrogen peroxide
摘要 采用
水溶液法制备了
六亚甲基四胺硝酸银[Ag(NO 3 )·N 4 (CH 2 ) 6 ]配位化合物,并通过
化学分析、XRD和电子显微镜对其进行了表征。通过热分析和质谱分析研究了[Ag(NO 3 )·N 4 (CH 2 ) 6 ]在
氢气和惰性条件下的分解。[Ag(NO 3 )·N 4 (CH 2 ) 6 ] 的热分解在 200–250 °C 范围内进行,这是一种伴随多种气体释放的自蔓延快速氧化还原过程。分解导致形成具有分级开孔系统的海绵状
银,孔径范围从 10 µm 到 10 nm。所获得的
银海绵对 H 2 O 2 电
化学还原表现出良好的活性,使其作为非酶
过氧化氢传感器具有潜在的吸引力。
