Colloidal CdS sensitized nano-ZnO/chitosan hydrogel with fast and efficient photocatalytic removal of congo red under solar light irradiation.

Colloidal CdS sensitized nano-ZnO/chitosan (CdS@n-ZnO/CS) hydrogel was prepared and characterized extensively by XRD, SEM-EDS, TEM, UV-Vis DRS, FT-IR and TGA. The photocatalytic activity of CdS@n-ZnO/CS was evaluated with the photodegradation of congo red (CR) as an organic pollutant under solar light irradiation. The influences of initial dye concentration, catalyst dosage, recycling runs, and radical scavenger on decolorization of CR by CdS@n-ZnO/CS were investigated.

Magnetic NiFeO/MWCNTs functionalized cellulose bioadsorbent with enhanced adsorption property and rapid separation.

Magnetic NiFeO nanoparticles and multi-walled carbon nanotubes functionalized cellulose composite (m-NiFeO/MWCNTs@cellulose) as a magnetic bioadsorbent was prepared and used for effectively removing Congo Red (CR) from aqueous solution. The chemical and physical properties of the prepared m-NiFeO/MWCNTs@cellulose were characterized by XRD, TGA, FT-IR, VSM, SEM and TEM. Batch experiments were carried out to investigate the adsorption capacity and mechanisms.

[Synthesis, characterization and electrocatalytic performance of Pd/CMK-3 for formic acid oxidation].

The synthesis of mesoporous carbons CMK-3 was implemented using SBA-15 samples as the hard templates and sucrose as the carbon source. Ordered mesoporous carbon CMK-3 supported palladium catalyst with a loading amount of 20% (Pd/CMK-3) was prepared by a complexing reduction method. XRD and TEM results showed that the p6mm hexagonal symmetric pore structures of CMK-3 were highly ordered and the Pd nanoparticles with the average size of 4.
