Photoinduced Interfacial Electron Transfer in 2,2’‐Bipyridyl Iron(III) Complex‐TiO₂ Nanoparticles in Aqueous Medium

Abstract

The near-UV and visible light induced interfacial electron transfer (IFET) process between aqueous solution of [Fe(bipy) 2 Cl 2 ][FeCl 4 ] complex and TiO 2 NPs has been proved at first time and the photochemical products were mainly characterized by electronic absorption, Fe K-edge X-ray absorption fine struc-ture, electron paramagnetic resonance and 57 Fe Mö ssbauer spectroscopic method. This study makes in comprehending for the combination of semiconductor NPs and metal complex, inparticularly ionic salt like complex has potential in environmental friendly synthesis and remediation process.[a] Dr.

Tuning the Magnetic and Photocatalytic Properties of Wide Bandgap Metal Oxide Semiconductors for Environmental Remediation

“…TiO 2 -based materials are widely used in environmental and energy-related applications like photocatalysis, photovoltaics, artificial photosynthesis, and spintronic, which have been often foreseen. For better performance, TiO 2 is usually employed as nanocrystals or nanostructures [71][72][73]. However, the efficiency of photocatalytic activity of TiO 2 needs to improve to induce charge carrier activity using visible light or sunlight.…”
