Effect of K+ cation doping on structural and morphology of MgFe2O4 and their role in green electrical energy generation

Abstract

Recent development in generation of green electrical energy using porous oxide is a promise of economic and sustainable energy source. Pure and K-doped MgFe2O4 based hydroelectric cells with mesoporous structure and good chemical stability were synthesised by solid-state sintering method. Energy production with zero carbon emission can be achieved by dissociation of water molecules with this novel device named as Hydroelectric cell. Rietveld analysis of powder X-Ray data was performed to investigate the structural and phase analysis of prepared samples. FESEM was used to depict the surface morphology of all the samples. Water molecules dissociation and ionic conduction of dissociated ions were further investigated by dielectric and dc conductivity measurements for all the samples in dry and wet states. Load analysis of cell was performed to understand its practical applications. Maximum out power was observed for Mg0.9K0.1Fe2O4 based Hydroelectric cell. Overall results conclude that K+ cation doping induce nano porous structure in MgFe2O4 results in better hydroelectric properties which may use as nonconvention source of energy.
