Palladium Particles Modified by Mixed-Frequency Square-Wave Potential Treatment to Enhance Electrocatalytic Performance for Formic Acid Oxidation
Round 1
Reviewer 1 Report
The paper describes the production of Palladium nanoparticles for the oxidation of formic acid to carbon dioxide and water and proposes their use in fuel cells. The work is thoroughly done and the electrochemical results are described in great detail. However, the literature is not cited adequately. For instance, the authors should add recent review articles (i.e. T. Shen et al, Energy Fuels, 2020, 34, 9137-9153). The authors should also explain all abbreviations when they appear in the text for the first time. The authors should also compare their catalyst with common Pd-catalysts used for formic acid oxidation (how much better is this new Palladium nanoparticle preparation in comparison to others?).
