FeNi-MIL53 bimetallic MOFs as a visible light photocatalyst for water oxidation

Photocatalytic water oxidation by iron and copper phthalocyanine complexes immobilized on Fe3O4@SiO2@TiO2 under visible light irradiation

“…phthalocyanine easily transferred to the TiO 2 conduction band are injected and MPc •+ radical cation is produced (2). Electrons are trapped in the conduction band of TiO 2 by silver ions and barricade the water reduction (3). As the electrons in the TiO 2 conduction band are trapped by the silver ion, the recombination of the internal charges is prevented and, as a result, the recombination is reduced as much as possible.…”

“…Over the past decade, there has been an emphasis on clean and renewable energy sources to prevent irreversible climate changes worldwide and meet growing energy demand. 1,2 Accelerating the decomposition of water molecules into hydrogen and oxygen via photocatalysis by the use of solar energy and ample water sources is one of the most promising instructions to treat the energy and environmental problems 3 attracting a great deal of attention. In the water decomposition reaction, oxygen generation being a problematic four-electron process 4 is imperative for renewable energy industries namely rechargeable metal-air batteries, 5,6 water splitting, [7][8][9][10] and water oxidation [11][12][13] playing a critical role in energy storage for example in solar fuel synthesis.…”
