“…In this work, we aim to synthesize novel Cu-Fe oxides composite lms by a one-step sparking process. This process has been developed in our lab which can prepare small, uniform particles, high porous lms, and determine the composite ratio [18][19][20][21][22][23][24][25][26]. Moreover, the sparking process requires neither complicated steps nor special equipment, cheap, fast, and non-toxic.…”

Copper-iron (Cu-Fe) oxide composite films were successfully deposited on quartz substrate by a facile sparking process. The nanoparticles were deposited on the substrate after sparking off the Fe and Cu tips with different ratios and were then annealed at different temperatures. The network particles was observed after annealed the film at 700°C. Meanwhile, XRD and SAED patterns of the annealed films at 700°C consisted of a mixed phase of CuO, γ-Fe2O3, CuFe2O4 and CuFe2O. The film with a lowest energy band gap (Eg) of 2.56 eV was observed after anneal at 700°C. Interestingly, the optimum ratio and annealing temperature show highly photocatalytic activity than annealed TiO2 at 500 and 700°C. This is a novel photocatalyst which can be replace TiO2 for photocatalytic applications in the future.

The nanoparticles were deposited on the substrate after sparking off the Fe and Cu tips with different ratios and were then annealed at different temperatures. The network particles were observed after annealing the film at 700 °C. Meanwhile, XRD, XPS and SAED patterns of the annealed films at 700 °C consisted of a mixed phase of CuO, γ-Fe2O3, CuFe2O4 and CuFe2O. The film with the lowest energy band gap (Eg) of 2.56 eV was observed after annealing at 700 °C. Interestingly, the optimum ratio and annealing temperature show the photocatalytic activity under visible light higher than 20% and 30% compare with the annealed TiO2 at 500 and 700 °C, respectively. This is a novel photocatalyst which can be replaced TiO2 for photocatalytic applications in the future.
