Abstract: A method for synthesizing pure metallic nanoparticles (MNPs) uses a direct electric arc process. The method involves arranging a pair of tungsten filament electrodes within a reaction chamber, connected via a graphite rod passed through a quartz tube. An aqueous solution of a metal nitrate precursor, preferably Fe(NO3)3·9H2O, is introduced into the quartz tube. An inert gas, preferably argon, is supplied to maintain an oxygen-free atmosphere. A high voltage is applied across the electrodes to generate an electric arc, which creates a localized plasma, vaporizing the metal ions in the solution. The vaporized metallic species are rapidly cooled and condensed in the inert atmosphere, forming metallic nanoparticles with high purity. The resulting nanoparticles are then collected and washed with water to remove residual contaminants.

Abstract: The present invention generally relates to a process for synthesizing a graphene oxide quantum dots-iron phthalocyanine (FePc-GOQDs) nanocomposite with enhanced electrochemical properties, particularly for oxygen reduction reactions (ORR).

The resulting composite is rinsed repeatedly with deionized water and ethanol, then dried at 120° C. to yield the FePc-GOQDs nanocomposite. This composite demonstrates superior ORR performance due to strong Fe—O bonding and optimized electronic interactions.

Abstract: The present invention generally relates to a system for producing activated carbon from cow dung. The process begins with a drying and washing unit to pre-treat the raw material. Dried cow dung is then milled and sieved to a specific particle size. A second drying step prepares the sieved material for carbonization in a nitrogen atmosphere. The resulting carbonized material undergoes chemical activation using a sodium hydroxide solution. Subsequent pyrolysis in a nitrogen environment further develops the pore structure of the activated carbon. The pyrolyzed material is then washed with hydrochloric acid to remove impurities. A final drying step yields the desired activated carbon product, which is then crushed. This system provides a controlled and efficient method for converting cow dung into valuable activated carbon, offering a sustainable waste management solution and a source of high-quality material for various applications.
