Synthesis of NiO-8YSZ nanopowders by co-precipitation method
and its structrual and microstructural characterization.

Abstract

This project is mainly based on the effect of synthesis route on the NiO-8YSZ samples prepared by co precipitation method by varying the weight percentage of NiO.
The fuel cell has tremendous future prospect not because of its high efficiency and low emission, and also for their modular and distributed nature and zero-noise pollution. This may solve our future requirement, as it plays an essential role in any future hydrogen fuel economy. YSZ has very good conductivity of O2-, the presence of Ni enhances the electronic conductivity. The composite of NiO-8YSZ is used to prepare Solid Oxide Fuel Cell’s (SOFC) anode part. This allows us to do further study to improve the sample for SOFC using co precipitation method.

Our objective in this present project include the synthesis of NiO-8YSZ using co precipitation method by varying the weight percentage of NiO as 0, 20, 30, 40 percentage respectively and study its structural and microstructural properties. It was studied that the calcine temperature of the samples comes around ~800 o C. The next part of the project is all about finding out the crystallite size and the lattice parameter of samples using XRD data and the SEM images, the SEM image shows that the samples are porous in nature.

Apparent porosity decreases with increase in wt % of NiO. Bulk density increases with increase in wt % of NiO. This helps us to synthesize sample best suitable for various applications.
