摘要: Nanocrystalline ZnFe 2 O 4 oxide-semiconductor with spinel structure was synthesized by the polymerized complex (PC) method and investigated for its photocatalytic photoelectric properties. The observation of a highly pure phase lower crystallization temperature in made PC is total contrast to that observed prepared conventional solid-state reaction (SSR) method. band gap nanocrystalline determined UV-DRS 1.90 eV (653 nm). activity as photo-decomposition isopropyl alcohol (IPA) under visible light (≥ 420 nm) much higher than 0 SSR well TiO 2-x N x . High mainly due surface area, crystallinity dispersity platinum metal over
