Abstract

Designs and developments of proton conductors are highly important in chemistry and energy fields. In this study, a novel metal–organic framework H2DAB-MgNi(ox)3 was synthesized. X-ray powder diffraction, scanning transmission electron microscopy, and scanning transmission electron microscopy-energy-dispersive X-ray mapping measurements demonstrated that the H2DAB-MgNi(ox)3 had a solid-solution structure, with the homogeneous distribution of Mg and Ni elements. The proton conductivity of H2DAB-MgNi(ox)3 was enhanced from that of H2DAB-Ni2(ox)3 at 95% relative humidity by Mg substitution.
