A heterojunction photocatalytic membrane consisting of Cu₂O and TiO₂ nanowires between reduced graphene oxide (rGO) sheets was fabricated using a facile process from a colloidal suspension. The resultant membrane exhibits significantly enhanced activity in the UV-vis range, surpassing nanowire dispersions, owing to the heterojunction formation and concurrent electron and hole transfer on rGO sheets. The membrane also possesses increased permeability and photocorrosion resistance. Such a design and fabrication method of an rGO-facilitated heterojunction photocatalytic membrane can be extended to a broad range of energy and environmental applications.

通过在还原的氧化石墨烯中嵌入Cu ₂ O和TiO ₂纳米线形成的高性能异质结光催化膜†

使用胶体悬浮液，采用简便的方法制备了由Cu ₂ O和TiO ₂纳米线在还原的氧化石墨烯（rGO）片之间组成的异质结光催化膜。由于异质结的形成以及在rGO板上同时发生的电子和空穴转移，所得的膜在UV-vis范围内表现出显着增强的活性，超过了纳米线分散体。该膜还具有增加的渗透性和耐光蚀性。rGO促进的异质结光催化膜的这种设计和制造方法可以扩展到广泛的能源和环境应用领域。
