“…Anatase phase shows four peaks in the spectra at roughly 141.7, 396.2, 515.1 and 639.3 cm -1 [36][37][38]. In Figure 5 it can be observed that the as-prepared TiO 2 nanotubes are characterized by a spectra without peaks, which is in agreement with an amorphous phase.…”

The latter is due to the fact that the hydrodynamic conditions eliminate part of the initiation layer formed over the tube-tops, which is related to an increase of the photocurrent in the photoelectrochemical water splitting. Besides, the photogenerated electron-hole pairs are facilitated by Li + intercalation. Finally, this work confirms that there is a synergistic effect between Re and Li + intercalation.

“…TiO 2 nanoparticles photocatalyst requirement of large amount of catalysts, difficulty in cata-lyst recycling and problematic agglomeration of TiO 2 nano crystals into large particles [27]. Although immobilized TiO 2 is the overall photocatalytic activity has been compromised due to the reduction of surface area and limitation in mass transfer [28]. In order to enhance photocatalytic activity and facilitate catalyst separation after photocatalytic reaction, one-dimensional(1D) nanostructured materials such as nanotubes, nanowires and nanorods have been investigated.…”

Alternate energy source becomes a crucial for green energy solution against ever increasing demand. Dye Sensitized solar cell is another promising option toward green energy providing opportunity to explore natural dye extracts from plants. This review explores recent developments in the field of Dye Sensitized solar cell technology specifically with sensitizer synthesized from plants which are also found in India. Anthocyanin, betalain, chlorophyll and carotenoids are among the most common plant pigments explored as sensitizers. The review of different attempts on fabrication of natural dye based solar cells implies that titanium dioxide (TiO 2 ) nano particles can be used as photoanode, platinum (Pt) as counter electrode and iodine/iodide electrolyte. Plant pigments are highly pH sensitive and can alter solar cell performance based on its extraction method, concentration and its ability to anchor with photoanode. Stability of dye, absorption in near IR range and leakage of liquid electrolyte are few of the challenges ahead. However, natural dye is biodegradable and non-toxic having most of the extraction process harmless to environment. In addition, natural dye has the promising future as it is abundant. …………………………………………………………………………………………………….... Introduction:-Exhaustion of fossil fuels lead the world to shift from the conventional energy sources to renewable energy to meet the growing energy demand. Although the process is gradual but the potential of renewable energy was well talked in the past decade. Wind energy is effective, but due to the inconsistency of the blowing wind, it is not quite efficient. Unlike wind energy, solar energy has a fair amount of consistency. As a result, the conversion of solar energy into different forms was the core of the research for the recent past years [1].Nanotechnology is a rapidly promising technology with vast potential in creating new materials with unique properties and to produce new and improved products for photo voltaic applications. The term nanoparticle refers to any small particle with all three dimensions less than 100 nanometres (nm) in size. It has a large surface area per unit mass. Titanium dioxide (TiO 2 ) nanomaterials are known for their numerous and different applications, which range from common products, such as sunscreens, to in advanced devices such as photovoltaic cells a series of environmental and biomedical applications such as photocatalytic degradation of pollutants, water purification, biosensing and drug delivery. The importance and variety of these applications have spur enormous interest and

“…As reported by the authors, the nanotubes can be recycled and re-applied in numerous photodegradation cycles, maintaining 90% of their activity after 10 cycles of the reaction. In contrast, the precursor of TiO 2 catalyst lost its activity during the second catalytic cycle [25].…”

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. of TNTs synthesized at 140°C was about 2.5 times higher than that generated with use of TiO 2 P25. To the best of our knowledge this is a first report on the photocatalytic generation of hydrocarbons using TNTs in the current state of the art.
