Abstract

Introducing sulfonic acid groups into MOF materials is one of the effective approaches to enhance proton conduction. Here, we attempted to prepare a new post-modified ZIF-90-based material by addition reaction of the aldehyde group with bisulfite to obtain partially functionalized ZIF-90-SONa. ZIF-90-SONa exhibits a high proton conductivity of 2.26 × 10 S cm at 98% RH and 100 °C.

摘要

将磺酸基团引入金属有机框架（MOF）材料是提高质子传导率的有效方法之一。在此，我们尝试通过醛基与亚硫酸氢盐的加成反应制备一种新型的基于后修饰ZIF-90的材料，以获得部分功能化的ZIF-90-SONa。ZIF-90-SONa在98%相对湿度和100°C下表现出2.26×10 S cm的高质子传导率。
