Abstract
Surface plasmon resonance excitation of gold nanoparticle-loaded on titanium(IV) dioxide (Au/TiO(2)) by visible light (lambda > 420 nm) has led to selective oxidation of thiol to disulfide, whereas the reaction is reversed by UV light irradiation (lambda > 300 nm).
摘要
可见光（lambda > 420nm）激发负载于二氧化钛（TiO(2)）上的金纳米颗粒（Au/TiO(2)）导致硫醇选择性氧化为二硫化物，而该反应可通过紫外光照射（lambda > 300nm）逆转。
