Copper-doped porous carbon nanospheres film (Cu@PCNF) was prepared via one-step ultrasonic spray pyrolysis (USP) for photocatalytic degradation of methyl orange (MO). The photocatalytic degradation rate reached 80% after 4 h under sunlight, and kinetic simulation results showed that the degradation reaction was a first-order reaction. Furthermore, the degradation rate did not decrease significantly after eight experiment cycles, which indicated that the film had good reusability and durability. This film synthesis technology provided a simple and effective strategy for improving the photocatalytic performance of contaminant treatment materials.
