dc.description.abstract | In this study, we have explored the deposition of highly monodispersed nickel nanoparticles on various supports using a two-step metal–organic precursor thermolysis and reductive annealing process. The process allowed flexible tunability of application-relevant properties, such as nanoparticle size, density and distribution, via the process pressure and deposition cycle control. Ex-situ characterization revealed the presence of carbon in the nanoparticles, necessitating the reductive annealing step to remove residual carbon. The impurities-free nanoparticles were subsequently deposited onto Pr0.5Ba0.5MnO3−δ anodes of solid oxide fuel cells and used to promote the electrochemical oxidation of methane. Impedance spectroscopy of the symmetric cells (Pr0.5Ba0.5MnO3−δ Yttria-stabilized ZrO2 Pr0.5Ba0.5MnO3−δ) revealed a significant enhancement in the catalytic activity of the Ni nanoparticle-coated electrode relative to the bare reference. Moreover, compared to conventional infiltration, the Ni nanoparticles deposited with the strategy outlined in this work showed over a 4-fold improvement in performance with an initial electrode resistance of only 2.1 Ω cm2. This highlights the important role of the deposition method on catalytic performance and the potential of developing highly active electrode materials for direct-hydrocarbon utilization. © 2023 The Authors | - |
