GaxCs2.5-3xH0.5PW12O40的固相法制备及其催化正丁烷异构化反应的活性

摘要

GaxCs2.5-3xH0.5PWl2O40(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.%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Ga0.1Cs2.2H0.5PW12O40和Ga0.15Cs2.05H0.5PW12O40最为显著.
