A Pt-Bi bimetallic nanoparticle catalyst for direct electrooxidation of formic acid in fuel cells

Liquid phase oxidation of cinnamyl alcohol to cinnamaldehyde using multiwall carbon nanotubes decorated with zinc-manganese oxide nanoparticles

“…For example, Mallat et al utilized platinum supported on alumina (Pt/Al2O3) for the conversion of cinnamyl alcohol (CnOH) to cinnamaldehyde (CnHO), showed a better conversion (88.5 %), selectivity, and separation of catalyst from the reaction medium [8]. A bimetallic Pt-Bi catalyst supported on activated carbon in the presence of hydrogen peroxide has been used, which showed better selectivity (84%), but poor conversion (34%) [9]. Scott et al, utilized metallic and bimetallic nanocrystal as a catalysts in aqueous medium and achieved ~34% conversion [10].…”

In–situ Synthesizing and Optimizing the Surface Structure of Nanoporous PtBi Electrocatalysts for Formic Acid Electro–oxidation

“…Among those, the PtBi electrocatalyst achieves excellent activity towards oxidation of FA. In view of taking the respective advantages of platinum and bismuth, varieties of PtBi nanocatalysts have been prepared to promote the catalysts’ activity towards FA oxidation . However, as bismuth species easily dissolve at higher potential, PtBi electrocatalysts mainly performed on a narrow potential range limiting to 0.8 V (Potentials given in this paper were all versus reversible hydrogen electrode, RHE.).…”

Recent Progress in Nanoparticle Synthesis via Liquid Medium Sputtering and its Applications

“…Moreover, in NPs, quantum effects can change or enhance properties such as reactivity, strength, and electrical characteristics [4]. Besides the ORR, NPs can catalyze many electrochemical reactions, including the hydrogen evolution [5,6], liquid fuel (e.g., methanol [7,8], ethanol [9,10] and formic acid [11,12]) oxidation, and carbon dioxide reduction reactions [13].…”
