Spintronic Hydrogen Evolution Induced by Surface Plasmon of Silver Nanoparticles Loaded on Fe and Co doping ZnO Nanorods

With increasing demand of sustainable energy, hydrogen as a recyclable and green energy resource draws a lot of attention. Optical spintronics combining the spin photoelectron thereby distinct itself as the most powerful and promising device for hydrogen production, through implementing surface plasmon resonance (SPR) in spintronic transport. A spintronic-photoelectrochemical (SPEC) hydrogen evolution device, as revealed, utilizing a coating of silver nanoparticles (NPs) onto TM:ZnO (TM: Fe, Co) nanorods (NRs), demonstrates an energy transfer due to the generation of spintronic surface plasmon resonance under a circular polarized light of coherent ħ / −ħ radiation. Moreover, the spin injection emerges in semiconductors through optical and electrical paths to modulate the process of spintronic transport across the interface. Evolution efficiency of the SPEC hydrogen and its corresponding maximum production of hydrogen successfully rise to as high as 174.46% and 1.70×10-3 L/s·m2, respectively, by exploiting spintronic SPR energy transfer. However, the spintronic can impede the SPR hot electrons to transfer and displays a quantum entanglement of the two qubits during spin-plasmon-electron interactions when attempting an increase of evolution efficiency of the SPEC hydrogen. We hereupon designed an unprecedent approach to realize the utilization of the strong spin-plasmon-electron interactions and have applied these techniques to yield a state-of-the-art device to bring spintronics into reality.
