| Abstract |
Interface has a synergetic effect in catalytic reactions. Nano particle zero Valent iron (nZVI) is high active (Oxidant, Reductant) of almost contaminants of wastewater such like nitrate through reduc...tion as part of water remediation. nZVI agglomeration lead to severely decreasing in surface area then hence drop in its activity. There were some additives served as anti-agglomeration such like polymers, bi-metals and stabilizers. However, metal oxide nanostructure could prohibit nZVI agglomeration furthermore create an interface with higher activity. TiO_2 as a photocatalytic material has same function after excitation with suitable energy. Electrons play main role for reduction while holes are for oxidation, and hence its efficiency depend on mainly in time recombination of electrons and holes. nZVI@TiO_2 successfully synthesized and demonstrated synergetic reduction removal activity for NO_3-. SEM have been used to analysis new composite structure, furthermore several batch experiments have been performed to suggest reduction possible scenario including future plan.show more
