Due to the great potential to improve catalytic performance, gold (Au) and palladium (Pd) bimetallic catalysts have prompted structure-controlled synthesis of Au-Pd nanoalloys bounded by high-index facets. In this work, we prepared Au-Pd bimetallic nanoflowers (NFs) with a uniform size, well-defined dendritic morphology, and homogeneous alloy structure in an aqueous solution by seed-mediated sy...

Unique kinked semiconductor-metal Au-Ag2S-ZnS and Au-Ag2S-ZnS-Au heteronanorods have been synthesized for the first time by a seed-mediated growth method. A plausible mechanism for the formation of kinked heteronanorods is proposed. The catalytic activity of such novel kinked semiconductor-metal heteronanorods with selective deposition and uniform morphology is also investigated via a model rea...

The encapsulation of noble-metal nanoparticles (NPs) in metal-organic frameworks (MOFs) with carboxylic acid ligands, the most extensive branch of the MOF family, gives NP/MOF composites that exhibit excellent shape-selective catalytic performance in olefin hydrogenation, aqueous reaction in the reduction of 4-nitrophenol, and faster molecular diffusion in CO oxidation. The strategy of using fu...

4 Nitrophenol (NP) or para nitrophenol (PNP) is one of the emerging pollutants from pesticides industries and it a major discharge any phenol consuming industry also severs as pharmaceutical wastewater. Design development photocatalytic treatment p-nitrophenol particularly to suit recovery reuse catalyst will aid in its commercial scale development. P-nitrophenol degradation has been studied ce...

In this study, we investigated the catalytic properties of N,N-dimethylformamide (DMF)-stabilized gold nanoclusters (AuNCs) in the reduction of 4-nitrophenol (PNP) to 4-aminophenol by NaBH(4), a well known model reaction to be catalyzed by metal surfaces. The DMF-stabilized AuNCs were prepared in DMF by a surfactant-free method. The DMF-stabilized AuNCs showed high catalytic activity even when ...

Double-shelled hollow carbon spheres with reduced graphene oxide (RGO) as inner shell and carbon (C) layer as outer shell have been successfully designed and prepared. This tailor-making structure acts as an excellent capsule for encapsulating with ultrafine Pd nanoparticles (Pd NPs), which could effectively prevent Pd NPs from aggregation and leaching. As a result, the as-obtained RGO@Pd@C nan...
