Porous BiOCl micro-flowers constructed from ultrathin nanosheets with nearly 100% {001} facets exposed were selectively prepared. The exposed {001} facets terminated with a high density of oxygen atoms and are not only favorable for the adsorption of the cationic dye RhB but also can accumulate the photogenerated electrons injected from excited RhB. These electrons can be captured by O(2) and t...

This study reports the capacities and mechanisms of live biomass of an ascomycetes strain, Aspergillus niger HM11 biomass preparations in removing a textile dye Reactive blue 140 from aqueous solution was investigated with different parameters, such as adsorbent dosage, pH, initial dye concentrations and equilibrium time. pH study and desorption profile proved that adsorption process was suppor...

We propose a highly oriented photochromic dye film for an ultraviolet (UV)-sensing layer, where spirooxazine (SO) derivatives are aligned with the liquid crystalline UV-curable reactive mesogens (RM) using a guest-host effect. For effective electrical UV sensing with a simple metal-insulator-metal structure, our results show that the UV-induced switchable dipole moment amount of the SO derivati...

A microporous H-type activated carbon was shown to be effective for removing anionic reactive dyes from single and binary component solutions. The extent of the dye adsorption from a single-solute solution was high (0.25– 0.42 mmol/g). From the binary dye solutions, the experimental data indicated a high degree of competition for active sites and the obtained adsorption capacities were reduced ...

Study on the photocatalytic decolorization of aqueous solution of Direct Red 23, a commercial azo-reactive textile dye, in the presence of UV light radiation. The effect of different reaction parameters on the photo catalyst of DR 23 was assessed best operational parameters were observed as photons: catalyst loading 1gm-3.0gm/50ml, pH 3.5-11.5, temperature 303k,dye concentration10mg/50ml-70mg/5...
