TiO(2) doping with N-rich melamine produced a stable, active and visible light sensitized nanocatalyst that showed a remarkable efficiency towards the photobleaching of a model compound - methylene blue (MB) in aqueous solution. The photobleaching followed a mixed reaction order kinetics with the distinctive induction and acceleration periods.

new type of heterogeneous nanocatalyst for deoximation based on tungsten oxide supported on mesoporousmolecular sieve mcm-41 was developed. this new system representes inexpensive and highly activeheterogeneous nanocatalyst for deoximation under green and mild reaction conditions.

molecular sieves mcm-41 were synthesized from rice husk ash (rha) as alternative sources of silica. the material was synthesized by a room temperature method from a gel with the molar composition sio2: 1.6ea: 0.215hdtmabr: 325h2o with ph correction. the cetyltrimethylammonium bromide (ctmabr) was used as a structure template. nanocomposite containing 5.0 and 10.0 wt.% of cu was synthesized unde...

nano-graphene oxide was synthesized by the oxidation of graphite powders. the structural nature of the nano-graphene oxide was characterized by a variety of techniques including xrd, tem, ft-ir and uv/vis. the functional groups on its basal planes and edges of nano-grahene oxide play important role in catalytic activity. the catalytic activity of nano-graphene oxide was investigated on crossed-...

Monodisperse Pt and PtRu/C(60) hybrid nanoparticles with controlled diameters were synthesized by the reduction of metal precursors in the presence of C(60); the resulting metal/C(60) hybrid nanocatalyst exhibited a remarkable enhancement of methanol oxidation activity over commercial E-TEK catalysts.

Globally, efforts are being made to upgrade and improvise the current wastewater treatment technologies. Industrial is generated exponentially, owing expansion in chemical industries civilizations necessitating remediation prevent further environmental damage lower associated human risks. In this work, iron oxide nanoparticles (IONPs) have been developed employed as an efficient nanocatalyst fo...

A poly(2-vinylpyridine)-block-poly(2-(4-vinylphenyl)pyridine) (P2VP106-b-PVPPy95) coil-coil diblock copolymer forms hollow flower micelles in a mixed solvent of methanol and water (95/5, v/v) in a one step process. The geometry and composition of the micelles allow formation of a Pt-Au bimetallic dendritic nanocatalyst with a Pt leaf at room temperature.

A ZnO nanocatalyst with a high percentage exposure of (0001) facets embedded on a hierarchical flower-like matrix has been prepared by an in situ topotactic transformation of a layered double hydroxide precursor, and exhibits significantly higher visible light photocatalytic performance than other ZnO nanomaterials with fewer exposed (0001) facets.

Cd-Al/C layered double hydroxide (Cd-Al/C-LDH) and Cd-Sb/C nanocatalyst are reported here for the de-coloration and mineralization of organic dyes. These catalysts were largely characterized by FESEM, EDS, XRD, FTIR, XPS, PL and DRS. The diffuse reflectance data showed a band gap at 2.92 and 2.983 eV for Cd-Al/C-LDH and Cd-Sb/C respectively. The band gap suggested that both catalysts work well ...
