New Nanotechnology Findings from Peking University Described (NiPt hollow nanocatalyst: Green synthesis, size control and electrocatalysis)

August 1, 2014

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Nanotechnology are presented in a new report. According to news originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "Nearly monodispersed hollow nanospheres of bimetallic NiPt have been synthesized by a one-pot wet chemical method at room temperature with a precursor Ni nanocompound as a sacrificial template. The size control is carried out via the sacrificial template, from about 35 nm to nearly 100 nm in diameter."

Our news journalists obtained a quote from the research from Peking University, "The shell thickness of the NiPt hollow sphere reaches down to as thin as 2-3 nm slightly larger than a single layer of alloyed NiPt nanocrystallites. The product with the citric acid as surfactant exhibits enhanced oxygen reduction activities compared to a commercial Pt/C catalyst and the hollow nanospheres coated with PVP."

According to the news editors, the research concluded: "It has potential applications in fuel cells, biotechnology and environmental chemistry with the facile synthesis, low cost and excellent electrocatalytic activity."
