“…Luévano-Hipólito et al [33,34] evaluated WO 3 and scheelite-type compounds in de-NO x photocatalytic reactions under ultra-violet (UV) radiation. Single phase TiO 2 -based materials have also been well evaluated for NO x degradation [35][36][37][38][39] as well as in heterostructures when combined with other phases, such as WO 3 , g-C 3 N 4 , amorphous carbon or hydroxyapatite [40][41][42][43].…”

The efficiency of photo-oxidation of pollutants catalysed by semiconductors is still limited for real-world applications due to several drawbacks, such as a) insufficient absorption of visible radiation, which predominates in solar spectrum, b) rapid free electron to hole recombination, c) small surface area, built from equilibrium crystallographic facets with low adsorption capacities and d) photo-corrosion. The present study disclosures new mesoporous heterostructures, built from exfoliated lepidocrocite-like ferrititanates and TiO 2 (anatase)-acetylacetone charge transfer complex, capable of reducing free electron-to-hole recombination rate through a robust charge separation and sensitive to the visible light spectrum. The synthesis route is based on soft-chemistry and low temperature calcination at 300°C. Two different partially pillarized heterostructures, denoted as HM-1 and HM-2, have been synthesized. It was observed that the heterostructure HM-1 was four times more active toward photocatalytic degradation of NO gas in comparison to the benchmark photocatalytic material P25. The lower activity of the heterostructure HM-2, comparable to that of P-25, was attributed to the high value of Urbach energy that indicates high number of defect sites within energy band-gap of the constituent semiconductor components. [Ti] anatase/[Ti] ferrititanate mol ratio might also play a role in photocatalytic efficiency.

“…On the other hand, the hydrophilic groups in the polymeric chain of PEG adsorbed at the surface of the crystal nuclei to prevent rapid growth of the particles. As basic copper carbonate grew mature, PEG and water molecules gradually departed from the particles which tended to form agglomerates in response to the minimum high surface energy [11,12]. Thus, aggregated basic copper carbonate flakes formed.…”

“…1b). During the formation of basic copper carbonate, PEG could act as a template direction agent to optimize growth orientation and growth rate [10,11]. OH -groups preferentially absorbed ether groups in PEG solution moved towards the long chain of the PEG to form the crystal growth of basic copper carbonate with a flake-like structure [12].…”

“…Tungsten oxide (WO3) is one of the nanoparticles metal oxide, which revealed super-hydrophobicity properties [3]. The tungsten oxide nanoparticles have been prepared with a variety of technologies including such as sol-gel [4], hydrothermal [5], thermal decomposition [6], acid precipitation [7], electrophoresis deposition (EDP) [8], chemical vapor deposition (CVD) [9], and physical vapor deposition (PVD) [10]. WO3 is utilized for various applications such as gas sensing [11], photo-catalyst [12], electrochromic windows [13], and electrochemical sensors [14].…”

This work introduces a simple method to prepare WO3 nanoparticles via tungsten rod electrooxidation in the presence of NaCl solution as an electrolyte. In this process, WO3 nanoparticles with sizes between 10nm and 20 nm were prepared and characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), and energy dispersive X-ray spectroscopy (EDX) techniques. WO3 nanoparticles are used to modify polysiloxane surface. The WO3 coated polysiloxane surface showed a very high-water contact angle of 158°.
