Plasmon-induced resonant energy transfer and flat band formation in Fe and Co doped Ni( ii ) hydroxide for efficient photocatalytic oxygen evolution
Year: 2025
Type: article
Abstract: Enhancing photocatalytic oxygen evolution is vital for renewable energy. In this work, we demonstrate how plasmon-induced resonant energy transfer (PIRET) from gold nanoparticles (AuNPs) to Fe and Co doped nickel hydroxide (Ni(OH)₂) can improve this process. PIRET involves the transfer of energy from excited AuNPs to nearby molecules, boosting their reactivity. We show that doping Ni(OH)₂ with Fe or Fe/Co reduces the band gap and forms flat bands, enabling efficient energy transfer and enhancing electronic properties. Our results show that NiFe layered double hydroxide (NiFeLDH) achieves superior oxygen evolution reaction (OER) activity than Ni(OH)₂ due to PIRET. This study demonstrates the crucial role of PIRET in enhancing plasmonic energy transfer and the synergistic effects of doping and AuNP coupling. These findings highlight the broader potential of material engineering in advancing efficient and sustainable energy technologies.
