Sustained solar fuel production in multiple thermochemical cycles using sol-gel derived ferrite nanopowders

Abstract

In this paper, the sol-gel synthesis of Mg-doped Niferrite i.e. Ni-Mg-ferrite was attempted by using propylene oxide (PO) as a proton scvanger. Effects of two important synthesis paramaters such as amount of PO added during synthesis and aging time on phyico-chemical properties such as phase composition, specific surface area (SSA), crystallite size, and particle morphology were studied by using different analytical methods such as powder X-ray diffractometer (PXRD), BET specific surface area analyzer, and scannning electron microscope (SEM).
