Photonic Fano Resonance of Multishaped Cu2O Nanoparticles on ZnO Nanowires Modulating Efficiency of Hydrogen Generation in Water Splitting Cell

摘要: The different-shape Cu2O nanostructured in solar water splitting system serves as the photon absorber structure for modulating photoelectric conversion to challenge issue of high resistance and low electronic mobility with different light trapping effect due orientation geometry Cu2O. Finite difference time domain (FDTD) simulation results demonstrate that truncated octahedral exhibits photonic Fano resonance compared other shapes. generation rate electrons holes can rise nanostructures on ZnO nanowires. By combining resonance, we use a lower voltage 0.7 V (the standard potential electrolysis is −1.23 V) water, then separate H2 O2 into electrodes. hydrogen reach 3 × 10–4 ml/s·cm2, which about 10 times higher than shapes by p...
