Developing a New Method for the Formation of NiO Hollow Microspheres Using Yeasts as Bio-Templates

Abstract:

A novel route for synthesis of biomorphic nickel oxide （NiO） hollow microspheres, using yeasts as bio-templates, has been successfully developed. In the typical process，yeast cells were first coated with nickel hydroxide and then calcinated to obtain nickel oxide hollow microspheres. As-prepared products were characterized by DTA, SEM, XRD and FTIR. A possible formation mechanism of NiO hollow microspheres was proposed in brief.
