“…Titanium dioxide (TiO2) is one of the most important metal oxides known for a long time, as it has been known since ancient times for its ability to act as a photocatalyst, and as a result of these two properties, its applications have expanded as it has become used in self-cleaning of building windows, and in the manufacture of cement, paints, and anti-dirt paints and dirt, as a result of these two properties (air purification system and water filters). TiO2's most important applications are dye applications [2,3]. One of the most important characteristics of TiO2 nanoparticles that have drawn the world's attention is that it is a white solid, thermally stable, non-flammable, and poorly soluble, in addition to being cheap and non-toxic or (environmentally and human-friendly).…”

Nanomaterials are engineered materials with extremely small particle sizes with at least one dimension ranging from one to one hundred nanometers. Nanoscale materials contain unique electrical, magnetic, catalytic, and optical properties that can be applied in various fields, including engineering, medicine, and the environment. Nanomaterials with appealing chemical and physical properties are being researched for potential energy and environmental applications. Nanomaterials have grabbed people's interest due to their ability to enhance efficiency through-beam gap control, chemical composition, structural diagram, light propagation, and charge/transport collection, among other things. Titanium dioxide (TiO2) nanoparticles are mass-produced all over the world for use in a range of applications. TiO2 nanostructured materials have aroused much interest in the energy and environmental sectors due to their future applications in photocatalysis, solar cells, and pollution remediation. Furthermore, because TiO2 nanoparticles are widely available, inexpensive, and non-toxic, they are routinely employed in various products, including cosmetics, where they are used as a UV filter in sunscreens, face creams, foundation, and lipstick. Analgesics. Because of the relevance of titanium dioxide, we will discuss it in this review by demonstrating its characteristics, photocatalysis mechanism, and uses that come into direct contact with human existence.

“…Rapid industrialization has resulted in the generation of huge volumes of wastewater containing toxic synthetic dyes from sectors like textiles, paper, plastics, leather, etc. It is estimated that over 7 × 10 5 metric tons of dyestuffs are produced worldwide annually, out of which 5-10% are discharged as effluents in water bodies(M. Abd Abdulah et al, 2022).…”

Water pollution caused by the discharge of dyes is a serious environmental problem worldwide.Cobalt-doped manganese aluminium ferrite CoXMn1-XAl0.2Fe1.8O4 (X=0,0.2) nanoparticles synthesized via the sol-gel combustion technique exhibited excellent photocatalytic activity for Congo Red dye degradation under visible light irradiation. Comprehensive materials characterization revealed their structural, optical, morphological, and electronic properties. XRD reveals a cubic spinal ferrite structure, FTIR shows cobalt incorporation, SEM shows nanoparticle morphology, EDX confirms stoichiometric composition, and BET analysis reveals a high surface area. Cobalt incorporation tunes the optical bandgap from 2.8 to 2.5 eV, enabling visible light absorption (UV-DRS). Dielectric and conductivity measurements confirm semiconductor behaviour and indicate cobalt doping introduces additional charge carriers. Cobalt-doped manganese aluminium ferrite exhibited excellent Congo Red dye photodegradation efficiency of 99.9% under normal conditions of pH 7, catalyst dose of 100 mg/L, and dye concentration of 10 ppm following first-order kinetics. Scavenger test observed Hydroxyl and superoxide radicals degrade dyes. Cobalt doping facilitates charge dynamics, narrowing the bandgap and enhancing interfacial charge transfer, leading to superior photocatalytic performance. Cobalt-doped ferrite nanoparticles are reusable. Cobalt-doped manganese aluminium ferrite is an efficient and stable photocatalyst for wastewater treatment.

Dye-sensitized solar cells (DSSCs) have attracted renewed research interest as a potential low-cost substitute for conventional silicon photovoltaics. This work aims to improve the photovoltaic performance of the DSSCs by incorporating multi-walled carbon nanotubes (MWCNTs) into the BaTiO3 photoelectrode. The pure BaTiO3 and BaTiO3/MWCNT nanocomposites were sensitized with N719 dye and fabricated into solar cell devices for testing. The structural characterization confirmed the successful formation of the nanocomposite with an optimal dispersion at 6% of MWCNT incorporation, beyond which agglomeration effects manifested. The optical analysis verified the modulation of defect states and bandgap engineering induced by the MWCNT network. The morphological studies revealed irregular nanoparticle clusters with embedded nanotubes. Solar cell testing under AM1.5G-simulated sunlight demonstrated a peak power conversion efficiency of 4.044% for 6% of MWCNT doping, constituting a 6-fold increment versus pure BaTiO3 (0.693%). It originated from the simultaneous enhancements in the open-circuit voltage and short-circuit current enabled by the favorable band structure alterations and percolation-assisted charge transport. However, further increasing MWCNT content deteriorated the device metrics, owing to emerging limitations like trapping. The rational integration of multi-walled carbon nanotubes with lead-free ferroelectric metal oxides can contribute to the development of emerging organic-inorganic hybrid solar platforms.
