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 ...

This study was conducted to investigate the use of cubic LaMnO3 nano-perovskite as a green catalyst for the degradation of an aqueous solution of methyl orange under different conditions. Nanoscale cubic lanthanum manganite with the particle size of ~20 nm was successfully synthesized via citrate sol-gel method. The sample was characterized using the FT-IR and UV-Vis spectroscopy, XRD, SEM, and...

An oxovanadium(IV) complex of dipyridophenazine, as a potent metal-based PDT agent, shows efficient DNA photocleavage activity at near-IR region and high photocytotoxicity in both UV-A and visible light in HeLa cells.

Within the range of validity of the stationary diffusion equation, an ideal diffusive-light invisibility cloak can make an arbitrary macroscopic object hidden inside of the cloak indistinguishable from the surroundings for all colors, polarizations, and directions of incident visible light. However, the diffusion equation for light is an approximation which becomes exact only in the limit of sm...

The hexagermane Pr(i)3Ge(GePh2)4GePr(i)3 has been synthesized and is not only the first such linear oligogermane to be structurally characterized but also is the first such compound to exhibit fluorescence and dichroic properties when observed under different orientations of plane polarized visible light.

A dynamic smart surface which was constructed by the self-assembly of an azobenzene-functionalised pillar[5]arene exhibits reversibly responsive morphologies towards UV and visible light as observed by TEM, SEM and AFM.

Gold doped TiO2 has been successfully synthesized via the photolysis method and is characterized by different techniques. NPs of gold doped TiO2 were utilized for the degradation of methylene blue as a material pigmentation pollutant. The substitution of Au on TiO2 surface was established via XRD, EDX, TEM, and FT-IR techniques. The TEM and SEM results appea...

Fully reversible photoswitching of the coordination mode of the ligand MeN4Py (1,1-di(pyridin-2-yl)-N,N'-bis(pyridin-2-yl-methyl)-ethan-1-amine) in its ruthenium(II) complex with visible light is reported. Irradiation with visible light results in dissociation of a pyridyl moiety, which is reversed by irradiation at 355 nm.
