摘要: 利用室温固相法制备了一系列掺镓的钨磷酸铯盐催化剂 GaxCs2.5-3xH0.5PW12O40 (x = 0.05, 0.1, 0.15). 与钨磷酸铯盐相比, 掺镓的钨磷酸铯盐催化剂的结构未产生变化, 但其酸强度提高, 在正丁烷异构化反应中催化活性增强, 其中以 Ga0.1Cs2.2 H0.5PW12O40 和 Ga0.15Cs2.05H0.5PW12O40 最为显著.

Abstract: GaxCs2.5-3xH0.5PW12O40 (x = 0.05, 0.10, and 0.15) salts were prepared using a solid synthesis method and they showed higher catalytic activity than that of Cs2.5H0.5PW12O40 for n-butane isomerization, which possibly comes from their enhanced acid strength as a result of Ga doping.
