“…Four different initiators are used for this. These are titanium tetraisopropoxide (TTIP) [ 35 ], titanium chloride (TiCl 4 ) [ 36 ], tetra-n-butyl orthotitanate (TBT) [ 13 ], and commercial titanium dioxide powder [ 37 ]. Nanoparticles between 1–100 nm are synthesized with all these initiators.…”

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. Titanium dioxide nanoparticles, which can be synthesized with toxic solvents or high-energy machines, have started to be synthesized by the green synthesis method, which has been a cheap and easy method in recent years. The application areas of these nanoparticles synthesized with renewable resources (leaves, roots, seeds, etc.) are increasing day by day. This article gives information about the synthesis of titanium dioxide nanoparticles with renewable resources and the application of these nanoparticles synthesized by means of chemical and green synthesis methods.

“…Rueda et al [ 35 ] prepared the extract of 50 g of tangerine peel selected as a solvent with 150 mL of distilled water for 2 h on a 400-rpm magnetic stirrer at 90 ± 3 °C. They would prepare a 1.5 Normality TTIP solution and mix it with tangerine peel extract in 2 different proportions.…”

“…From the same category of fruits, lemon peel extract showed lower reducing potential as TiO 2 NPs obtained were higher in size (Nabi et al, 2020). Also, NPs synthesized via tangerine peel extract had a variable size range of 50 to 150 nm (Rueda et al, 2020). Smaller NPs were obtained using Annona squamosa peel extract (Roopan et al, 2012).…”

In the green synthesis of titanium dioxide nanoparticles (TiO2 NPs) chemical reagents are replaced with biological extracts. Conventional methods used in the manufacture of TiO2 NPs raise environmental issues as they use harmful chemicals and spend a high amount of energy. At a laboratory scale, biologically synthesized titanium dioxide nanoparticles (bio-TiO2 NPs) proved to be a suitable alternative to the chemically synthesized ones. The biological activity of NPs is mainly determined by their shape, size and crystalline structure. However, these characteristics are hardly controlled when natural sources of reagents are used and so bio-TiO2 NPs did not reach an advanced technology readiness level. In this paper, we reviewed the majority of the available studies referring to bio-TiO2 NPs. Our aim is to briefly present the efficiency of biochemicals from different living organisms in producing TiO2 nano-scale particles as well as the benefits bio-TiO2 NPs would bring to the biomedical, agricultural and industrial sectors. Finally, based on the available data we discuss the sustainability of bio-TiO2 NPs referring to their possible environmental, economic and societal impacts.

“…Semiconductors such as hematite Fe 2 O 3 [ 8 , 9 , 10 ], tungsten trioxide WO 3 [ 11 , 12 , 13 ], and TiO 2 [ 14 , 15 , 16 ], as well as perovskites including ABX 3 [ 17 ], SrTiO 3 [ 18 ], metal oxides [ 19 ], and metal sulfides [ 20 ], have been used for this purpose. However, due to its low cost of production [ 21 ], easy availability, non-toxicity [ 22 ], and thermodynamic stability, TiO 2 anatase has been investigated meticulously [ 23 , 24 ]. Modern industrialization, technological development, and the rapidly growing global population have caused higher energy consumption, which has resulted in severe environmental pollution due to the burning of hydrocarbons.…”

Modulating Optoelectronic and Elastic Properties of Anatase TiO2 for Photoelectrochemical Water Splitting

et al. 2023

Titanium dioxide (TiO2) has been investigated for solar-energy-driven photoelectrical water splitting due to its suitable band gap, abundance, cost savings, environmental friendliness, and chemical stability. However, its poor conductivity, weak light absorption, and large indirect bandgap (3.2 eV) has limited its application in water splitting. In this study, we precisely targeted these limitations using first-principle techniques. TiO2 only absorbs near-ultraviolet radiation; therefore, the substitution (2.1%) of Ag, Fe, and Co in TiO2 significantly altered its physical properties and shifted the bandgap from the ultraviolet to the visible region. Cobalt (Co) substitution in TiO2 resulted in high absorption and photoconductivity and a low bandgap energy suitable for the reduction in water without the need for external energy. The calculated elastic properties of Co-doped TiO2 indicate the ductile nature of the material with a strong average bond strength. Co-doped TiO2 exhibited fewer microcracks with a mechanically stable composition.
