采用化学溶液法结合自旋镀膜工艺制备了金纳米颗粒分散的co3o4复合薄膜。在可见光（λ> 400 nm）下，研究了Au分散Co3O4（Au/Co3O4）薄膜的光催化作用。与纯co3o4膜相比，Au/ co3o4复合膜中出现了一个明显的表面等离子体共振峰（SPR）。复合膜在630 nm处产生的SPR峰与Au含量以及Au与[Co2+Co23+O4]之间的电荷跃迁密切相关。当Au含量为40 mol%时，Au/ co3o4复合膜在可见光照射下对刚果红（CR）溶液的降解表现出优异的光催化活性，表明本研究中Au/ co3o4复合膜具有高效的SPR推进效应，可以增强其可见光活性光催化作用。
Au nanoparticles (NPs) dispersed Co3O4composite films were fabricated via a chemical solution approach combined with a spin-coating processing. The photocatalysis on Au-dispersed Co3O4(Au/Co3O4) films were investigated under a visible light (λ> 400 nm) irradiation. Compared with the pure Co3O4film, an additional and significant surface plasmon resonance (SPR) peak appeared in the Au/Co3O4composite films. The SPR peaks aroused at around 630 nm in the composite films were strongly related to Au content and the charge transition between Au and [Co2+Co23+O4]. Au/Co3O4composite films with 40 mol% Au content exhibited the superior photocatalytic activity for degradation of Congo red (CR) solution under the visible light irradiation, suggesting the highly effective SPR propelled effect for enhancing the visible-active photocatalysis on the Au/Co3O4composite films in this study.
