【摘要】 采用微波辐照法制备了水溶性聚乙烯吡咯烷酮稳定的氧化铂纳米颗粒,并对产物进行了UV-Vis、TEM和XPS等表征。在调节反应溶液的pH值时,加入一定量的乙酸钠,所制得的纳米颗粒粒径小、分布窄、稳定性好。更多还原

【Abstract】 Polyvinylpyrrolidone（PVP）-stabilized PtO₂ nanoparticles were prepared by using microwave irradiation in water solution,and were characterized by UV-Vis,TEM and XPS examinations.When sodium acetate was added for adjusting pH value of the solution,the nanoparticles had smaller particle size with narrower distribution and better stability.更多还原
