Synthesis and Characterization of Copper Oxide-Titanium Dioxide One-Dimensional Composites for Photocatalysis
Aseel Adnan Ouda and Firas Kamil Mohamad Abstract: In the present paper, efficient and low-cost metal oxide systems, such as one-dimensional (1D) CuO/TiO2 submicro-composites, were synthesized via a two-step polyol-mediated solvothermal process. Titanium(IV) isopropoxide and copper(II) nitrate trihydrate were used as precursors. The CuO/TiO2 composites were prepared by varying the CuO loading (1 and 3 wt.%) and calcined at 450 °C for three hours. The effect of CuO doping on the structural and morphological properties of TiO2 was investigated using X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and energy-dispersive X-ray spectroscopy (EDX). The structural findings for all the prepared samples showed anatase with a tetragonal crystal structure. The morphological image confirmed that the TiO2 and CuO dopant nanoparticles bound together, forming a nano-rise-like structure. The results showed that the length of the CuO/TiO2 composite decreased with increasing weight percentage. The CuO/TiO2 composite at 1 wt.% exhibited the optimal average length and diameter of 2.902 µm and 0.406 µm, respectively, compared to the 3 wt.% composite. According to these findings, the obtained TiO2-doped CuO can be used as a binary metal oxide for visible-light photocatalytic applications.
Keywords: Micro-Rise-Like Structure, Composite, Polyol Method, CuO/TiO2.
