Smart Functionalized NanoMaterials “1, 2 and 3 D” For Energy Storage, Biosensing, Water and Soil Treatment

from Fundamental to Applied Research

Abstract

Materials/Composites/Hybrids properties and their application are often affected by several experimental parameters like growth conditions (used precursors, temperature, time). Moreover, electroactive functional material performance in numerous applications especially those related to energy storage, catalysis, biosensing and environment have attracted considerable attention of several researchers in last years. Therefore, more environmentally friendly, faster and energy-efficient synthesis processes for nanostructured production are currently of interest; especially for transition metal hydroxide and/or carbon nanostructures.

Thus, our research team aim in LEREC laboratory at Annaba University is focalized on developing several kind of nanomaterials and nanohybrids (1D, 2D and 3D) based of transition metal hydroxide/oxide and/or carbon micro-nanostructures as well as quasi nanostructured conductor polymers.

Basing on the earlier ideas postulated by researchers on designing and developing electrode materials with reasonable electrochemical properties, we present in this contribution some results obtained in our LEREC laboratory through the successful synthesis of mono-, bi- and ternary transition metallic hydroxides based of Ni, Co, Mn, Fe and Zn with carbonate (CO3)2- and/or hydroxide (OH)- intercalated ions by using a free-template one-step hydrothermal method, depicting a simple, efficient and low cost growth route. We will also present some results from in-situ hydrothermal growth Hydroxides/Graphene or MWNTs nanohybrids as well as Fe nanofibers based oxides. The as-obtained products have been generally identified via different characterization techniques, such as: XRD, Raman and FTIR (structural identification), BET (textural/porosity properties), TGA/DTA (thermal analysis), FE-SEM and HRTEM (morphological aspect) as well as XPS spectroscopy (electronic states).
