Abstract
In this study, we introduced 1H-1,2,4-triazole into the ordered nanochannels of propyl amino functioned MCM-41 and then investigated the hybrids' proton conducting performance.
Highlights
Proton-conducting solids play a pivotal role in proton exchange membrane fuel cells (PEMFCs)
It is observed in Tri@MS-PrNH2-3 that the central core of the silica sphere is almost hollow (Fig. 1(f)), which shows that the increment of propyl amino groups inside the silica impeded the 1H-1,2,4-triazole's accommodation procedure
In order to further demonstrate the effect of the functional groups on the conductivity, we used the pure MCM-41 without propyl amino groups to load the 1H-1,2,4-triazole and found that the hybrids didn't exhibit obvious proton conductivity until 90 C, its highest conductivity obtained at 110 C is only 10À5 S cmÀ1 (Fig. S5†)
Summary
Proton-conducting solids play a pivotal role in proton exchange membrane fuel cells (PEMFCs). Heterogeneous hybrid of propyl amino functionalized MCM-41 and 1H-1,2,4-triazole for high efficient intermediate temperature proton conductor† We introduced 1H-1,2,4-triazole into the ordered nanochannels of propyl amino functioned MCM-41 and investigated the hybrids' proton conducting performance.
