PROCESS OF SYNTHESIS OF GRAPHENE OXIDE QUANTUM DOTS-IRON PHTHALOCYANINE (FEPC-GOQDS) NANOCOMPOSITE COMPOSITION

Resumen de: US2025332576A1

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 process begins by dispersing 500 mg of graphene oxide (GO) in a hydrogen peroxide and deionized water solution in a 1:10 volume ratio, followed by hydrothermal treatment at 180° C. for 8 hours to produce GO quantum dots (GOQDs). The resulting material is freeze-dried to obtain GOQDs powder. Subsequently, 60 mg of GOQDs are combined with 10 mg of iron phthalocyanine (FePc) and 20 mL of dimethyl sulfoxide (DMSO), and the mixture is subjected to microwave irradiation at 500 W and 150° C. for 30 minutes. 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.

Resumen de: US2025338384A1

A microwave plasma torch equipment includes a reaction chamber, a ventilation tube and a microwave source. The reaction chamber has a reaction area, a microwave inlet, a first divert channel, a second divert channel and a microwave diverter. Each of the first and second divert channels has first and second end parts. The first end parts are coupled to the microwave inlet. The second end parts are coupled to each other at the reaction area. The cross-sectional areas of the first end parts are greater than those of the second end parts. The microwave diverter is located at the junction of the microwave inlet and the first and second divert channels. The ventilation tube penetrates through the reaction area along a direction substantially perpendicular to the extending direction of the first and second divert channels. The microwave source is located at the microwave inlet and facing the microwave diverter.
