“…On the other hand, numerous investigations have used high power irradiation sources (300-1000 W) to study photocatalytic processes [38][39][40]. In addition, to the best of our knowledge, the use of low power light (such as light-emitting diodes [LEDs]) in photocatalysis using polymeric films was further investigated recently [37].…”

The search to deliver added value to industrialized biobased materials, such as cellulose derivatives, is a relevant aspect in the scientific, technological and innovation fields at present. To address these aspects, films of cellulose acetate (CA) and a perylene derivative (Pr) were fabricated using a solution-casting method with two different compositions. Consequently, these samples were exposed to dimethylformamide (DMF) solvent vapors so that its influence on the optical, wettability, and topographical properties of the films could be examined. The results demonstrated that solvent vapor could induce the apparent total or partial preferential orientation/migration of Pr toward the polymer–air interface. In addition, photocatalytic activities of the non-exposed and DMF vapor-exposed films against the degradation of methylene blue (MB) in an aqueous medium using light-emitting diode visible light irradiation were comparatively investigated. Apparently, the observed improvement in the performance of these materials in the MB photodegradation process is closely linked to the treatment with solvent vapor. Results from this study have allowed us to propose the fabrication and use of the improved photoactivity “all-organic” materials for potential applications in dye photodegradation in aqueous media.

“…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.
