摘要: We fabricated plasmonic gold nanoparticle (AuNP)–TiO2 nanocomposite films and measured the photocurrent that originates from water-splitting reaction catalyzed by AuNP–TiO2 photoelectrocatalytic (PEC) electrode. The localized surface plasmon resonance (LSPR) of nanoparticles affected generation TiO2 upon illumination with visible light. Electrochemical impedance spectroscopy (EIS) revealed improvement in an enhancement electron–hole pair induced SPR rather than extension electron lifetime. Moreover, we introduced a novel method to enhance multiple effect, i.e., LSPR grating-coupled propagating SP on grating. nanocomposites gold-coated Blu-ray disc recordable (BD-R). due combination was investigated.
