Metal Hydroxide Salt Monolayer Nanoparticles: Synthesis, Redox Characterization, and Electrochemical Catalytic Performance

Abstract: Two-dimensional materials modified with low molecular weight species are known to show unique electronic properties. In this study, we focus on the synthesis and electrochemical investigation of metal hydroxide salt monolayer nanoparticles modified with different molecules toward improved electrochemical functions. Nickel hydroxide carboxylate nanoparticles were successfully prepared through the epoxide-mediated alkalinization method using alkylcarboxylates. It was found that the monolayer nanoparticles with a… Show more

“…Although d SAXS is slightly larger than d TEM , this trend is due to the lower electron density of the acrylate moiety compared to that of the metal hydroxide moiety, as reported in our previous study. 47 The chemical composition of Co 0.5 Ni 0.5 HA was estimated using TEM-EDS. The atomic ratio of Co : Ni was 0.47 : 0.53, which is comparable to the nominal molar ratio.…”

“…In the following studies, well-dispersed MHS nanoparticles were obtained using monocarboxylates such as acetate instead of dicarboxylates such as malonate. [46][47][48] Acrylate was employed in this study to synthesise MHS monolayer nanoparticles composed of cobalt, nickel, and cobalt-nickel bimetals. In situ measurements using spectroscopic techniques revealed the successful formation of a solid-solution MHS.…”
