A new triazine-based covalent organic polymer (named COP-NT), which showed high catalytic activities for the degradation of acidic and basic dyes, is synthesized. Its structure characteristics were fully investigated, which featured large specific surface area, homogeneous porosity, strong visible light absorption, excellent thermal stability and semiconductor performance. The as-prepared COP-N...

hydrothermal synthesis of nickel-chitosan hybrid  has  been accomplished using ni(ch3coo)2,4h2o, chitosan and water as starting material, template and solvent respectively, followed by calcination at 800 and 900˚c to provide nanoporous nio800  and nio900. the solid products were characterized by x-ray diffraction (xrd), nitrogen adsorption-desorption, scanning electron microscopy (sem) and four...

A novel strategy for the stitching of a tripodal ligand into a bi-metallic two-dimensional (2D) coordination polymer has been reported. The reaction of 5-nitrosalicylaldehyde based ligand H3L with nickel acetate resulted in the metal functionalized 2D extended network via potassium induced activation of the nitro group of the ligand. The compound is highly active towards photo-degradation of or...

This manuscript describes a synthesis of nanocrystalline TiOF2 film. The nanocrystalline TiOF2 becomes chemically attached to the surface of the glass slide. These films are robust and can be recycled as photocatalysts for the degradation of organic dyes and solvents. These films also have significant antibacterial properties upon irradiation.

Single-crystal NaY(MoO(4))(2) thin plates dominated by high-energy {001} facets were hydrothermally synthesized under relatively mild conditions, free of organic additives, seeds and templates. The as-obtained NaY(MoO(4))(2) thin plates showed an excellent visible-light-responding photocatalytic activity for degradation of dyes in water.

A new kind of silver indium tungsten oxide (AgIn(WO(4))(2)) mesocrystals with high hierarchy can be synthesized by a microwave-assisted approach, which shows high and selective photocatalytic activity for the degradation of different organic dyes under UV and visible light irradiation.

To elucidate the roles of graphene in photoelectric events and mass transfer during photocatalytic process is important for engineering graphene-semiconductor hybrid photocatalyst. Here, we demonstrated reduced graphene oxide (RGO) capturing dyes and photoinduced electrons during photocatalytic degradation of organic dyes in water. It captures dyes from water through adsorption and desorption i...

Experimental techniques are developed to determine the applicability of a particular luminescing center for use in a luminescent solar concentrator (LSC). The relevant steady-state characteristics of eighteen common organic laser dyes are given. The relative spectral homogeneity of such dyes are shown to depend upon the surrounding material using narrowband laser excitation. We developed three ...
