Synthesis of SnCdO3/rGO with high electrocatalytic performance for oxygen evolution reaction
The production of highly effective and stable electrocatalysts for OER (oxygen evolution reaction) has become challenging for sustainable energy production. The present study uses the simple hydrothermal approach to prepare a noble-metal free electrocatalyst, i.e., SnCdO3/rGO. The successful production of bimetallic oxide with rGO composite was proved by physiochemical data, illustrating the crystal structure of prepared SnCdO3 material. Moreover, adding rGO to the SnCdO3 leads to the dispersion of nanoparticles onto the nanosheets, improving the material’s overall surface area, as proven by BET analysis. The electrochemical testing verifies the transmission of four electron mechanisms by displaying the reduced Tafel value (36 mV dec−1), and a reduced overpotential of 227 mV. These findings suggest that the material is highly active as a catalytic material during OER operation and remains stable for 50 h under the alkaline condition, as evidenced by the chronoamperometry testing. Hence, this novel electrocatalyst can potentially replace noble catalysts and open a new pathway for non-noble metal-based electrocatalysts in future energy conversion applications.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
