Solid Synthesis of GaxCs2.5-3xH0.5PW12O40 Salts and Their Catalytic Activity in the Isomerization of n-Butane

Abstract

Ga x Cs 2.5-3 x H 0.5 PW 12 O 40 ( 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 Cs 2.5 H 0.5 PW 12 O 40 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 Ga x Cs 2.5-3 x H 0.5 PW 12 O 40 ( 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 Ga 0.1 Cs 2.2 - H 0.5 PW 12 O 40 和 Ga 0.15 Cs 2.05 H 0.5 PW 12 O 40 最为显著. A solid synthesis method was used to prepare a series of Ga doped Cs 2.5 H 0.5 PW 12 O 40 salts and the products show enhanced acid strength leading to higher n -butane isomerization activity compared with Cs 2.5 H 0.5 PW 12 O 40 .
