Nickel nanoparticles supported by commercial carbon paper as a catalyst for urea electro-oxidation
Nickel nanoparticles supported by commercial carbon paper (CP) are prepared by pulsed laser deposition with deposition time of 3, 6, and 12?min as a catalyst for urea electro-oxidation. The surface conditions and the morphologies of the prepared electrodes have been characterized by Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy. Urea electro-oxidation reaction in KOH solution on the Ni/CP electrodes is investigated by cyclic voltammetry and chronoamperometry. The results show that the electrode with less Ni nanoparticle agglomeration shows higher peak current density, which was achieved in the 3?min deposition samples when normalized by electroactive surface areas. However, the highest current normalized by the area of the carbon paper was achieved in the 6?min deposition sample due to the larger quantity of Ni nanoparticles. All the samples show good stability. Our results suggest that the low density, low cost, and environmental friendly CP can be used as support for Ni nanoparticle as a catalyst for urea electro-oxidation. It thus has great potential for many applications involving urea oxidation, such as wastewater treatments.
期刊介绍：
Energy is the single most valuable resource for human activity and the basis for all human progress. Materials play a key role in enabling technologies that can offer promising solutions to achieve renewable and sustainable energy pathways for the future.
Materials for Renewable and Sustainable Energy has been established to be the world''s foremost interdisciplinary forum for publication of research on all aspects of the study of materials for the deployment of renewable and sustainable energy technologies. The journal covers experimental and theoretical aspects of materials and prototype devices for sustainable energy conversion, storage, and saving, together with materials needed for renewable fuel production. It publishes reviews, original research articles, rapid communications, and perspectives. All manuscripts are peer-reviewed for scientific quality.
Topics include:
1. MATERIALS for renewable energy storage and conversion: Batteries, Supercapacitors, Fuel cells, Hydrogen storage, and Photovoltaics and solar cells.
2. MATERIALS for renewable and sustainable fuel production: Hydrogen production and fuel generation from renewables (catalysis), Solar-driven reactions to hydrogen and fuels from renewables (photocatalysis), Biofuels, and Carbon dioxide sequestration and conversion.
3. MATERIALS for energy saving: Thermoelectrics, Novel illumination sources for efficient lighting, and Energy saving in buildings.
4. MATERIALS modeling and theoretical aspects.
5. Advanced characterization techniques of MATERIALS
Materials for Renewable and Sustainable Energy is committed to upholding the integrity of the scientific record. As a member of the Committee on Publication Ethics (COPE) the journal will follow the COPE guidelines on how to deal with potential acts of misconduct. Authors should refrain from misrepresenting research results which could damage the trust in the journal and ultimately the entire scientific endeavor. Maintaining integrity of the research and its presentation can be achieved by following the rules of good scientific practice as detailed here: https://www.springer.com/us/editorial-policies
