Co–Ni nanoparticle supported on heteroatom-doped carbon derived from garlic powder and eutectic solvent: Its application in Nitroarenes reduction

This paper presents the synthesis of a novel heterogeneous catalyst, PSN-C600-Co2:Ni1, designed for the hydrogenation of nitroaromatic compounds. The catalyst is a porous carbon substrate triply doped with nitrogen, sulfur, and phosphorus, incorporating bimetallic Co and Ni nanoparticles. A natural precursor, garlic biochar, and a biodegradable eutectic solvent were used in the synthesis. Various characterization techniques, including Scanning Electron Microscope (SEM), X-Ray Energy Diffraction Spectroscopy (EDX), Elemental Mapping Measurements (MAP), Thermogravimetric Analysis (TGA), X-Ray Diffraction (XRD), Infrared Spectrometer (FTIR), Transmission Electron Microscope (TEM), Raman Spectroscopy, and Nitrogen Adsorption and Desorption Pattern (N₂ adsorption-desorption isotherm), were utilized to examine the features and properties of the synthesized PSN-C600-Co2:Ni1 catalyst.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
