Abstract
Abstract Bi2Ti2O7 nanopowders were synthesised via two different methods i.e. Pechini (P) and Co-Precipitation (C) method by annealing at 550 °C for 16 h. The effect of synthesis technique on photocatalytic activity of Bi2Ti2O7 nanopowders was extensively studied. Formation of pure Bi2Ti2O7 pyrochlore phase was observed in both samples. Various crystallographic parameters obtained by reitveld analysis of X-Ray Diffraction (XRD) spectra of both samples infer the formation of a highly loose crystallographic structure in P sample. The smaller crystallite size of P sample correlates with the observed blue shift in the Raman spectra, furthermore decreasing the particle size in P sample. P sample exhibits higher specific surface area, mean pore diameter and total pore volume which is inferred by Brunauer-Emmett-Teller (BET) analysis. Higher photocatalytic activity of P sample can be attributed to the formation of distorted crystallographic structure and higher specific surface area.
