Anatase TiO2 nanotubes (ATNT) was synthesised by hydrothermal method using anatase TiO2 nanoparticles (AT) as precursor and calcined at two different temperatures (250 & 450 °C) for 2 h. The AT and synthesized ATNT photocatalysts were characterized by X-ray diffraction, transmission electron microscopy, N2 adsorption-desorption measurements, UV-vis diffuse reflectance and Fourier Transform Infra-red spectroscopy techniques for their structural, textural and electronic properties. The photocatalytic degradation of Indigo carmine (IC) dye aqueous solution has carried out using ATNT-250 and ATNT-450 photocatalysts under UVLED irradiation. The kinetic analysis has also revealed that the degradation of IC dye solution follows first order kinetic model. The overall study demonstrates the appropriate band gap of the photocatalysts used and the suitable irradiation source which could accelerate the rate of photocatalytic degradation. The band gap of the synthesised ATNT is not much affected due to the change in morphology from nanoparticle to nanotube. The results demonstrated that the irradiation of UV-LED could be utilised for the degradation of organic dyes

AbstractA new two-dimensional ZnII coordination framework [Zn(1,3-BMIB) (OBA)]n (1) (where H2OBA is 4,4ʹ-oxy-bis(benzoic acid) and 1,3-BMIB is 1,3-bis(2-methyl-1-imidazolyl)benzene) has been prepared and characterized through IR spectroscopy, elemental and thermal analysis, and single-crystal X-ray diffraction. Complex 1 is a (4, 4) grid coordination polymer with a layer structure. It exhibits high photocatalytic degradation effects upon UV irradiation of methylene blue and methylene orange aqueous solutions.

The processes of interaction of an aqueous solution of an organic dye: methylene blue (MB)  C16H18N3SCl with gamma quanta and electrons were investigated. A model has been developed and the passage of electrons with an energy of 15 MeV through tungsten layers with a thickness of 1…8 mm has been simulated. Based on the simula-tion results, a number of experiments were carried out. Analysis of the calculated and experimental data showed that one incident electron destroys 4 times more dye molecules than one incident gamma quantum.
