ZnIn 2 S 4 /Au納米片陣列的制備及其可見(jiàn)光響應(yīng)光電化學(xué)固氮特性(英文)
發(fā)布時(shí)間:2021-04-07 15:43
采用簡(jiǎn)單的水熱法合成出單晶ZnIn2S4納米片陣列以實(shí)現(xiàn)可見(jiàn)光響應(yīng)光電化學(xué)固氮。并采用光沉積法將超細(xì)Au納米顆粒(5 nm)沉積于ZnIn2S4納米片的棱角位置處,實(shí)現(xiàn)了可見(jiàn)光俘獲和載流子分離能力的同時(shí)增強(qiáng)。當(dāng)負(fù)載合適含量的Au納米顆粒,ZnIn2S4納米片陣列的光電固氮活性由1.092μg·cm-2·h-1提升至2.262μg·cm-2·h-1。我們還提出一個(gè)簡(jiǎn)單模型用以闡明其性能增強(qiáng)機(jī)制,這也被光致發(fā)光(PL)譜和光電化學(xué)(PEC)性能結(jié)果所證實(shí)。
