Special Issue Information

Dear Colleagues,

Applications in energy storage and conversion relies heavily on the discovery of novel materials. By exploiting materials at the nanoscale, tremendous advancements have been made that have grown many industries (e.g. semiconductor, vehicle electrification, photonics, etc.).

Novel nanostructured materials are the centerpiece for emerging technologies. The synthesis and processing of nanostructured materials plays a key role in the adoption by such technologies as batteries, fuel cells, and supercapacitors. Moreover, the characterization of such materials becomes more critical, as our understanding of phenomena occurring at atomistic length scales relies heavily on novel characterization techniques equipped with a synchrotron source.

Research in novel nanostructured materials for energy-related applications requires the dissemination of new and exciting research, and we therefore welcome contributions from many different fields. Topics of interest include, but are not limited to the following:

Keywords

  • Synthesis
  • Batteries
  • Supercapacitors
  • Fuel Cells
  • Electrocatalysis
  • Water harvesting
  • Electrodeposition
  • New Materials
  • Processing

Catalytic electroreduction of carbon dioxide represents a promising technology both to reduce CO2 emissions and to store electrical energy from discontinuous sources. In this work, electrochemical deposition of copper on to a gas-diffusion support was tested as a scalable and versatile nanosynthesis technique for the production of catalytic electrodes for CO2 electroreduction. The effect of deposition current density and additives (DAT, DTAB, PEG) on the catalysts’ structure was evaluated. The selectivity of the synthesized catalysts towards the production of CO was evaluated by analyzing the gaseous products obtained using the catalysts as cathodes in electroreduction tests. Catalyst morphology was deeply influenced by the deposition additives. Copper nanospheres, hemispherical microaggregates of nanowires, and shapeless structures were electrodeposited in the presence of dodecyltrimethylammonium bromide (DTAB), 3,5-diamino-1,2,4-triazole (DAT) and polyethylene glycol (PEG), respectively. The effect of the deposition current density on catalyst morphology was also observed and it was found to be additive-specific. DTAB nanostructured electrodes showed the highest selectivity towards CO production, probably attributable to a higher specific surface area. EDX and XPS analysis disclosed the presence of residual DAT and DTAB uniformly distributed onto the catalysts structure. No significant effects of electrodeposition current density and Cu(I)/Cu(II) ratio on the selectivity towards CO were found. In particular, DTAB and DAT electrodes yielded comparable selectivity, although they were characterized by the highest and lowest Cu(I)/Cu(II) ratio, respectively. Full article
