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 structure, electron paramagnetic resonance and 57 Fe Mössbauer spectroscopic method. This study makes in comprehending for the combination of semiconductor NPs and metal complex, in‐particularly ionic salt like complex has potential in environmental friendly synthesis and remediation process.
