Abstract

Using visible light conditions, we have developed a green protocol to prepare copper oxide-doped graphitic carbon nitride (Cu₂O@g-C₃N₄) photocatalysts with varied ratios of g-C₃N₄ nanosheets to copper oxide-dopant (0.1 %, 0.5 %, 0.7 %, and 5 % respectively) and characterized through various physicochemical techniques. These photo-responsive catalysts were used for the 1,4 radical oxidative addition of trans crotonaldehyde into β-hydroxybutyric acid (BA) as a major product, utilizing 30 % hydrogen peroxide as an oxidant and a white LED (Light Emitting Diode) source. Under the innoculous eco-friendly stipulations, Cu₂O@g-C₃N₄ (5 %) exclusively promoted the aforementioned reaction leading to 99.85 % trans crotonaldehyde conversion with 66.57 %, 24.1 %, and 9.1 % selectivity for β-hydroxybutyric acid, crotonic acid and subsequent radical synthesis, respectively.

在可见光条件下合成用于反式巴豆醛 1, 4 自由基氧化加成的 Cu2O@g-C3N4 光催化剂的绿色方案

利用可见光条件，我们开发出了一种制备氧化铜掺杂石墨化氮化碳（Cu2O@g-C3N4）光催化剂的绿色方案，g-C3N4 纳米片与氧化铜掺杂剂的比例各不相同（分别为 0.1%、0.5%、0.7% 和 5%），并通过各种理化技术对其进行了表征。这些光响应催化剂被用于以 30% 过氧化氢为氧化剂和白光 LED（发光二极管）为光源，将反式巴豆醛 1,4 自由基氧化加成为主要产物 β-羟基丁酸 (BA)。在无害环保的条件下，Cu2O@g-C3N4（5%）能完全促进上述反应，使反式巴豆醛的转化率达到 99.85%，对 β-羟基丁酸、巴豆酸和后续自由基合成的选择性分别为 67.57%、24.1% 和 9.1%。
