“…Discharge of inorganic and organic pollutants from varying industries including printing, textiles, food, and beauty products into environmental water resources has been a main environmental problem in all countries regardless of how they are developed. Up to date, different methods based on physical, chemical, and biological treatments such as membrane processes, reverse osmosis, photocatalytic degradation, photo-Fenton, ozonation, oxidation, biological, as well as electrochemical procedures have been used for remediation of industrial wastewaters (Barbusiński, 2005;Farré et al, 2005;Liu et al, 2007;Dogan and Turkdemir, 2012;Ioannou et al, 2013;Zheng et al, 2013;Suresh et al, 2014;Suresh et al, 2016;Jesudoss et al, 2017;Rajan et al, 2017;Kooshki et al, 2019;Peymani-Motlagh et al, 2019a;Peymani-Motlagh et al, 2019b;Rahimi-Nasrabadi et al, 2019;Sobhani-Nasab et al, 2019aSobhani-Nasab et al, 2019c). Among the most commonly mentioned methods which are subject to restrictions, photocatalytic degradation systems act as a smart tool, because it is simple, highly efficient, and inexpensive (Basith et al, 2014;Vijaya et al, 2017;Sedighi et al, 2018;Eghbali-Arani et al, 2018;Sobhani-Nasab et al, 2019d).…”

The new nanocomposite with various molar ratios along with magnetic properties was fabricated via precipitation (assisted by ultrasonic) procedure. The photocatalytic effects of methylene blue (∼90% degradation for optimized sample in 100 min) for finding the optimized sample performed under visible light irradiation. Moreover, the photo-antibacterial impacts of bacteria culture environments were found with an optimized sample that had effective destruction of bacteria in comparison to control group. The cytotoxicity properties of panc1 cells and magnetic behaviors of the obtained nanomaterials were evaluated and its IC50 was about 500 mg/L. As an initial step, the structural, morphological and magnetic characteristics of the fabricated nanocomposites were evaluated by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) and MAP, UV-visible diffuse reflectance spectroscopy (DRS), and vibrating sample magnetometry (VSM) approaches. Based on SEM results, the size of nanoparticles in fabricated nanocomposite was nearly 50-70 nm for Fe 3 O 4 /SiO 2 /TiO 2 and 80-100 nm for Fe 3 O 4 /SiO 2 /TiO 2 /CeVO 4 . XRD results showed that desired nanocomposites were truly synthesized without any impurities.

The development of new generation photocatalytic materials used for the betterment of human as well as environment. Perovskites and perovskites related nano-hetero-junction shows great interest for photocatalytic organic and inorganic pollutant removal. This chapter discusses its crystalline structures varying from cubic (high symmetry) to triclinic (very low symmetry). Various methods have been utilized for synthesis of perovskites such as sol-gel, hydrothermal, vapor deposition methods, solid-state reaction routs from oxide and high pressure technique. The first technique is used for the synthesis of perovskite is ceramic route in which the mixture of oxide was treated at high temperature and processed later by ceramic powder method. Various photocatalyst such as nitrides, sulphides, phosphides, oxide and mixed oxide are employed for photocatalytic water splitting or hydrogen generation. Future perspectives of perovskite-related photocatalyst are included in this chapter.

In this work presents an approach for the selection of dye sensitized Cr-ZnO and Ni-CdO nanoparticles as a photo anode material for the applications of DSSCs. The 4 wt% Cr-ZnO and Ni-CdO nanoparticles were synthesized through simple and fast microwave combustion method. X-ray difraction (XRD) was used for the detection of crystalline phases and size of the synthesized nanomaterials. It confirms the existence of hexagonal wurtzite phase of Cr-ZnO (30-35 nm) and cubic phase of Ni-CdO (43-45 nm) nanoparticles. SEM and TEM micrographs of Cr-ZnO and Ni-CdO reveal that the synthesized samples are prismatic and spherical shaped, respectively. Optical absorption of Cr-ZnO and Ni-CdO nanoparticles before and after sensitization with Trypan Blue (TB), SPADNS (SPD) and Evans Blue (EB) dyes were examined through UV-Visible spectroscopy. The results show that the selected dyes improve the absorption edge of Cr-ZnO and Ni-CdO nanoparticles to longer wavelength side. HOMO and LUMO energy levels of the dyes were calculated by cyclic voltammetry. I-V characteristics of Cr-ZnO and Ni-CdO films before and after sensitization with dyes revealed the influence of dye sensitization on photo conductivity of Cr-ZnO and Ni-CdO nanoparticles.
