• behavior. Herein, we report a novel approach for the fabrication of a Cu/CuO/porous carbon nanofiber (PCNF)/TiO2 (Cu/CuO/PCNF/TiO2) composite that is uniformly covered by TiO2 nanoparticles and is synthesized using the electrospinning method together with a hydrothermal technique, followed by air

• distance between tip of the needle and collector was maintained at 15 cm and a DC voltage of 17 kV was applied. The collected as-spun nanofiber mats were first air-stabilized at 280 °C for 2 h and carbonized at 800 °C in inert atmosphere to produce Cu/porous carbon nanofiber (Cu/PCNF). A similar procedure
