Bimetallic Nanoparticle Synthesis via Microwave Irradiation

The patent employs microwave irradiation parameters (power, time, frequency) to precisely control the reduction process of metal precursors, enabling systematic control over nanoparticle composition and size. By adjusting microwave heating parameters, the patent achieves tunable metal ratios and particle dimensions while maintaining a relatively simple overall process framework.

The patent utilizes microwave irradiation to induce rapid heating and phase transitions in the reaction medium, enabling controlled reduction of metal precursors. The microwave energy is efficiently converted to thermal energy, providing precise control over nucleation and growth processes while maintaining reasonable energy consumption through optimized irradiation parameters.

The patent replaces conventional thermal conduction heating with microwave irradiation, which provides volumetric heating and more uniform temperature distribution throughout the reaction mixture. This substitution enables better control over the reduction process, resulting in nanoparticles with improved catalytic activity and selectivity, while the energy is used more efficiently due to direct coupling with the reaction medium.
