Surface basicity mediated rapid and selective adsorptive removal of Congo red over nanocrystalline mesoporous CeO.

Herein we first report surface basicity mediated rapid and selective adsorptive removal of organic pollutants over nanocrystalline mesoporous CeO. The role of surface features in controlling the selectivity and efficiency of adsorption is well known. Nevertheless, the possibility of tuning the adsorption capacity and selectivity of adsorbents through their surface characteristics remains less explored.

Ternary 3D reduced graphene oxide/NiZnFeO/polyindole nanocomposite for supercapacitor electrode application.

A facile two-step strategy has been reported for the preparation of a ternary 3D reduced graphene oxide/NiZnFeO/polyindole nanocomposite (GNP) and this composite is applied as an electrode material for supercapacitor applications. Remarkably, NiZnFeO nanoparticles (NZF) decorated on reduced graphene oxide (GN2) are achieved by a facile hydrothermal method followed by coating with polyindole (PIN) through an emulsion polymerization process. The structure, porosity, morphology, and thermal stability of the resulting ternary GNP hybrid material were characterized X-ray diffraction (XRD), Raman spectroscopy, Brunauer-Emmett-Teller (BET) surface area measurements, transmission electron microscopy (TEM), and thermogravimetric analysis (TGA).

g-CN/CuO and g-CN/CoO nanohybrid structures as efficient electrode materials in symmetric supercapacitors.

Metal oxide dispersed graphitic carbon nitride hybrid nanocomposites (g-CN/CuO and g-CN/CoO) were prepared a direct precipitation method. The materials were used as an electrode material in symmetric supercapacitors. The g-CN/CoO electrode based device exhibited a specific capacitance of 201 F g which is substantially higher than those using g-CN/CuO (95 F g) and bare g-CN electrodes (72 F g).
