Development of Bio & Electro-active  Nanomaterials

  • Anisotropic Nanomaterials  

Synthesis of metal nanoparticles is a major research area in nanoscale science and engineering owing to their unusual chemical and physical properties, such as catalytic activity, novel electronic, optical and magnetic properties and their potential applications in biotechnology. The major objective is to synthesize nanoparticles of different shape and investigate their electrocatalytic, biocatalytic and SERS properties. Gold nanoparticles of flower-shape, prism, periwinkle, and cube; Ag nanopartcles of branched shape and Pd nanoparticles of fractal and garland shapes, Pt nanoparticles of branched shapes have been synthesized in aqueous solution and characterized by various techniques.

  • Carbon Based Nanomaterials ( Graphene, Carbon Nanodots)

The ground breaking properties of graphene have recognized in many emerging applications. Similarly, the unique properties of carbon nanodots have recognized as best alternative nanostructures for many promising applications.  These are found to be eco-friendly, nontoxic, photo chemically stable and nonblinking. Here new methods have been developed for synthesis of graphene and carbon nanodots for various applications.

  • Metal Based Nanomaterials (Metal oxides/chalcogenides/Phosphides)

The selection of the good and efficient electrode materials is very much essential for energy conversion, storage, electrocatalytic and bi-catalytic applications. Therefore, for substantial efforts have carried to explore new materials of comparable efficiency. Here we developed  the new synthesis methods for syntheses of variety of Transition Metal based 0D, 2D and 3D nanomaterials such as MoSQuantum Dots(QDs), MOFs, NiSe2, MoS2, Nickel Phosphides, Co2P, FeOOH, ZnO, MoO2, VO2, CuWO4, transition metal oxide Calcium Cobaltite, Cu2O, NiCo2O4, β-NiMoO4, Cu3P, ZnCo2O4 and etc.

  • Hybrids/Composites Nanomaterials

To improve the catalytic performance, the nanostructured catalyst requires supporting material with high conductivity and large surface area. It not only enhances the catalytic activity but also provides stability by preventing the extensive aggregation of nanoparticles. We made our effort to develop variety of hybrids/composites of nanomaterials on graphene, SnO2 or mesoporosus silca with Noble metals, Metal oxides based materials for their synergistic promising applications of interest. For examples, Graphene hybrids of Graphene-(Mn3O4, Pt, Pd, Au/Pd, Au@Pd, Porous Pd, Au@Porous Pd, Vo2D, MoS2, NiCo2O4, ZnCo2O4, Ag nanowires) Pt-SnO2, AgNPs-Mesoporous silica, Au-ZnO and etc.
