Examples
Embodiment 1
[0018] 0.1mmol ethylbenzene, 0.02mmol NHPI and 10mgα-Fe 2 o 3 Disperse in 1mL of acetonitrile, fill with 1atm of oxygen, react at room temperature, 18W, 455nm light for 8 hours, centrifuge and use GC to analyze the sample. The conversion rate of ethylbenzene is 89%, the main product is acetophenone, and the yield is 87%.
Embodiment 2
[0020] 0.1mmol ethylbenzene, 0.02mmol NHPI and 10mgγ-Fe 2 o 3 Disperse in 1mL of acetonitrile, fill with 1atm of oxygen, react at room temperature, 18W, 455nm light for 4 hours, centrifuge and use GC to analyze the sample. The conversion rate of ethylbenzene is 19%, the main product is acetophenone, and the yield is 16%.
Embodiment 3
[0022] 0.1mmol ethylbenzene, 0.02mmol NHPI and 10mg Fe 3 o 4 Disperse in 1mL of acetonitrile, fill with 1atm of oxygen, react at room temperature, 18W, 455nm light for 4 hours, centrifuge and use GC to analyze the sample. The conversion rate of ethylbenzene is 6%, the main product is acetophenone, and the yield is 6%.
