研究了樹枝狀大分子摻雜的氧化銅（CuO）和負載氧化鋅（ZnO）的納米纖維素膜在二氧化碳光還原方面的性能。使用多元醇方法合成氧化鋅以獲得 20 nm的尺寸。綠色的氧化銅團簇摻雜到氧化鋅表面，以提高效率並減少電洞的複合。將樹狀聚合物摻雜到CuO和ZnO表面上以增強二氧化碳的捕獲。將催化劑加載到納米纖維素中，並乾燥成類似於天然葉片的薄膜。產品仍將保留在薄膜內，並且可以通過將薄膜分散到水中來輕鬆檢測。在氣相中使用間歇式反應器進行二氧化碳的光催化還原。光催化劑懸掛在反應器內，滴入少量的水。摻雜在負載ZnO的納米纖維素膜（Den-CuO＃5-ZnO / TOCNF）上的（5 mM Cu2+ 前體）樹枝狀CuO將二氧化碳轉化為甲醇，並且在沒有CuO的情況下將甲醇轉化為兩倍以上，在6小時內為 484±75 µmole。

The performance of dendrimer doped copper oxide (CuO) and zinc oxide (ZnO) loaded nanocellulose film on carbon dioxide photoreduction is studied. Zinc oxide is synthesized using polyol method to gain 20 nm size. Green color copper oxide nanocluster is doped into zinc oxide surface to increase efficiency and reduce electron-hole recombination. Dendrimer is doped onto the CuO and ZnO surface to enhance the carbon dioxide capture. The catalyst is loaded into nanocellulose and dried as film mimicking natural leaves. The products will be still inside the film framework and easily detect by dispersing the film into water. Photocatalytic reduction of carbon dioxide is using batch reactor in gas phase. Photocatalyst is hung inside the reactor with little drop wise of the water. Dendrimer-CuO (5 mM Cu2+ precursor) doped onto ZnO loaded nanocellulose film (Den-CuO#5-ZnO/TOCNF) converted carbon dioxide into methanol and more than two times of system without CuO, 484 ±75 µmole in 6 hours.
