Solution-Based Preparation, Characterization And In Situ Thermodynamics Kinetics Investigation Of Cadmium Molybdate Nano-Octahedra

As an important inorganic nanomaterial, cadmium molybdate (CdMoO₄) with a scheelite structure has received great research interest over the past few decades for its potential applications in various ?elds, such as optical ?bers, scintillators, photoluminescence, laser, magnetic properties, catalysis, humidity sensors, et al. This paper focused on the controlled synthesis of typical cadmium molybdate nanostructures via a facile liquid-phase route, evaluating the relationship between the shape and properties of the as-fabricated nanoparticles, and investigating the thermodynamics and kinetic of in situ growth and reaction of CdMoO₄ nanomaterials for the first time.Uniform CdMoO₄ nano-octahedra have been designed and synthesized by employing a nonionic TritonX-100-based reverse microemulsion technique at room temperature. A possible mechanism for the formation of CdMoO₄ nano-octahedra has been proposed by altering the experimental parameters.The analysis on the photoluminescence spectra of the CdMoO₄ crystals with various sizes and morphologies reveals that luminescence properties of CdMoO₄ are sensitive to its structure and strongly dependent on the crystal size. The CV studies show that CdMoO₄ nano-octahedra could apparently enhance the direct electron transfer of the modi?ed electrode. The present work indicates that it will be a hopeful nanomaterial which could be used in photoelectronic and sensor.The in situ growth and reaction thermal efficiency of CdMoO₄ was first explored by adopting calorimetry technique.
