The ZnO NRs/CuO composite film exhibits significantly enlarge absorption range to visible-light and suppress the recombination rate of the photogenerated electron-hole pairs, which can be well utilized as a photocatalyst. The ZnO NRs/CuO composite film also presents good stability, and reusability, and durability for photo-decomposition purpose. The optimal ZnO NRs/CuO composite film contains 1μ-thick of CuO film and 10 nm-thick of ZnO NRs film. The donor concentration in ZnO NRs film should be lower than 1016 cm−3. The short circuit current density of the optimal composite film is 25.8 mA/cm2 resulting in the calculated pseudo-order rate constant of 1.85 s−1. The enhancement in degradation efficiency of this composite film is attributed to the inner electric field and large effective surface area of ZnO NRs film. date: 2020-05-08 date_type: published publisher: Nature Publishing Group full_text_status: public publication: Scientific Reports volume: 10 number: 7792 refereed: TRUE issn: 2045-2322 related_url_url: https://www.nature.com/articles/s41598-020-64784-w related_url_type: pub citation: Nguyen, Thi Dung and Tran, Minh Duc and Hoang, Van Thanh and Trinh, Duc Thien and Pham, Duc Thang and Nguyen, Dinh Lam (2020) Experimental and numerical study on photocatalytic activity of the ZnO nanorods/CuO composite film.
