Keywords: Tin oxide Sol–gel process Nanoparticle Photocatalysis Phenol degradation Visible light a b s t r a c t Iodine doped tin oxide (SnO 2 :I) nanoparticles were prepared by sol–gel synthesis and their photocatalytic activities with phenol as a test contaminant were studied. In the presence of the catalysts, phenol degradation under direct sunlight was comparable to what was achieved under ...

We report straight pores in titanium dioxide produced by a pattern transfer method with titanium fluoride hydrolysis. The resulting films on fluorine-doped tin oxide had pores with diameters of 30 nm and depths of 500 nm, corresponding to aspect ratios of 1:17.

nickel doped tio2 nano particles (1% w/w) were prepared and immobilized on nax zeolite and after characterization by x-ray diffraction (xrd) and scanning electron microscopy (sem) used as photo catalyts for degradation of orange g. the xrd patterns show that the supported tio2 are crystallized in anatase form and the intensity of the zeolite peaks decreases with the increase of tio2 loading. sc...

    Nano technology has a large number of applications in different fields of science and technology. Nano particle are the tiny particles which are being used in upcoming technology due to their small size and high capability. The properties of nanoparticles depend largely on their synthesis procedures. There are different methods for the synthesis of nano particles using differen...

the electronic structure, energy band structure and electronic density of 2 sno ceramic in cubicphase have been investigated using first principle full potential-linearized augmented plane wave (fp-lapw)method within density functional theory (dft). local density approximation (lda) and the generalizedgradient approximation (gga), which are based on exchange- correlation energy optimization wer...

3,3,6,6-tetramethyl-9-phenyl-3,4,6,7,9,10-hexahydroacridine-1,8-(2h,5h)-dione derivatives are synthesized by nano titanium dioxide as an efficient and reusable heterogeneous nano catalyst in a one pot multi component reaction. easy preparation and separation of catalyst, simply workup procedure, clean reaction and reusability of the catalyst up to 7 times without appreciable loss of its catalyt...

Nano-structured CuO-Cu2O complex thin film-based perovskite solar cells were fabricated on an indium tin oxide (ITO)-coated glass and studied. Copper (Cu) thin films with a purity of 99.995 % were deposited on an ITO-coated glass by magnetron reactive sputtering. To optimize the properties of the nano-structured CuO-Cu2O complex thin films, the deposited Cu thin films were thermally oxidized at...

sn02 nanowires with diameters of 30 — 200 nm have been synthesized by using carbothermalprocess via a thick film of tin dioxide and carbon powder precursor. the nanowires werecharacterized by x-ray power diffraction (xrd), scanning electron microscopy (sem),transmission electron microscopy (tem) and selected area electron diffraction (saed).the gas sensing characteristic of nanowires toward eth...
