ABSTRACT
In the present investigation, a series of zinc ferrite (ZnFe2O4) nanoparticles were synthesized using a facile, reproducible and scalable chemical co-precipitation route for sunlight assisted photocatalytic degradation application. In the present work, we have prepared ZnFe2O4 with 1:1, 1:2 and 1:3â¯M ratio of zinc chloride and ferric chloride respectively. This work reports the photodegradation of organic methylene blue dye molecules using ZnFe2O4 under both normal sunlight, and collected sunlight. Among other annealing temperatures, particularly the ZnFe2O4 annealed at 600⯰C with a molar ratio of 1:3 showed the highest photocatalytic degradation of methylene blue. Interestingly close to 99% degradation in less than 60â¯min of collected sunlight illumination has been achieved indicating maximum photocatalytic activity under investigation. This expounding study will open new way of light harvesting in the field of photocatalysis which is different from common praxis.
