| Abstract Scope |
Metal nanoparticles (NPs) exhibit unique characteristics such as the high specific surface area, particle size-dependent optical and electronic properties, have attract worldwide attention towards the application in catalysis, sensing, microelectronics and drug delivery, etc. As one of the most facile synthesis approaches for metal NPs, microwave-assisted polyol reaction has gained considerable interest because of the shorter reaction period with significantly reduced energy consumption and lower environmental impact compare with conventional heating process. Herein, Pt NPs were synthesized via altered microwave-assisted polyol reaction as an attempt to obtain NPs with controlled core-state crystallinity for the first time, during where the reaction dynamic of precursor, particle growth and crystallization mechanisms were elucidated in details. In addition, a novel route of microwave-assisted polyol reaction was also clarified in present. The synthesized NPs with well-controlled structure perform excellent catalytic activity for air pollution control even under a trace loading amount (1/100 to conventional case). |
