In this study, a TiO2-CeO2 heterostructure was synthesized using a cost-effective hydrothermal technique, suitable for continuous industrial-scale production and environmental remediation applications. The photocatalytic activity of the TiO2-CeO2 heterostructure was examined with MB dye under visible light irradiation. Significantly enhanced photocatalytic activity was observed compared to pure TiO2 nanoparticles.

The silver nanoparticles are synthesized by the green method using Salix semi-solid extract. Fresh leaves are prepared in a semi-solid extract form that retains active substances and can be preserved for a long time. The parameters of the synthesis process are optimized by examining the effects of pH, Salix semi-solid extract concentrations of extract and AgNO3 concentrations through the UV-Vis absorption spectrum of synthetic particulate solutions.

Multiferroic materials refer to a class of materials which possess the intrinsic coupling of two or more ferroic orders (ferroelectric, ferroelastic, and ferromagnetic). Among them, magnetoelectric materials exhibiting both ferroelectric and ferromagnetic characteristics have received much attention due to their great potential in multifunctional applications such as spintronics, memory, and sensors.

Metal-oxide nanoparticles have reached a wide range of applications in the last ten years. Titanium dioxide nanoparticles stand out with their unique crystal structure and near-perfect physical and chemical properties at nanoscales (crystal size between 10–100 nm). It has created many applications with its white pigment, semiconductor state, and effective photocatalytic properties, but the synthesis of these nanoparticles is very damaging to nature.

The photocatalytic hydrogen production of TiO2 is limited by the rapid rate charge recombination. The co-operation of CuxO (CuO or Cu2O) and TiO2 is an effective method to overcome this drawback. In this study, the CuxO/TiO2 composite structure is fabricated by hydrothermal method and chemical deposition technique.
