系列水滑石化合物催化KBH4水解析氢的活性研究
Studies on catalytic performance for hydrogen production from KBH4 of series hydrotalcite
【摘要】 采用共沉淀法、强碱水热法及尿素水热法合成Ni/Al、Mg/Al、Zn/Al、Ni/Fe、Zn/Fe、Zn/Cr、Co/Fe等七个系列水滑石类化合物并将其用于催化KBH4水解析氢,催化析氢结果表明:Ni/Al组分活性最高,从合成方法的角度看:尿素水热法>强碱水热法>共沉淀法.
【Abstract】 A series of hydrotalcite such as Ni/Al,Mg/Al,Zn/Al,Ni/Fe,Zn/Fe,Zn/Cr,Co/Fe were synthesized by co-precipitation method,alkali and urea hydrothermal methods.These hydrotalcites were applied to the desorption of KBH4.The results indicate that the Ni/Al active ingredients was the best,and urea hydrothermal method>alkali hydrothermal method>co-precipitation method according to synthetic methods.
