Abstract
The perovskite-type zinc hydroxy stannate, ZnSn(OH)6, (ZHS) has gained remarkable attention owing to its intrinsic structural versatility and multifunctional characteristics, promoting major innovations in modern technology. In this work, the perovskite ZHS nanoparticles (NPs) are synthesized through a simple and cost-effective co-precipitation route, enabling the precise interaction of sodium stannate and zinc sulphate for the formation of a well-defined perovskite framework. The X-ray diffraction pattern elucidated the crystallization of ZHS in a well-defined cubic unit cell structure with a = b = c = 7.75 Å. The CHNS/O analysis detected the presence of hydrogen and supported the hydrogen incorporation within the lattice. The elemental analysis using energy dispersive analysis of X-ray verified the elemental composition. The field emission gun scanning electron microscopy and field emission gun transmission electron microscopy clearly identified the cubic shape of NPs. The diffuse reflectance spectroscopy confirmed a direct optical band gap of 5.70 eV. Raman and Fourier transform infrared spectroscopy collectively delineated phonon vibrations of Zn–OH–Sn bonds and OH– stretching modes. Thermal stability and decomposition mechanism are examined by recording three different thermocurves: thermogravimetric, differential thermogravimetric, and differential thermal analysis. The non-isoconversional Kissinger method is applied to evaluate kinetic parameters, providing a novel approach that highlights the non-spontaneous disintegration of the ZHS material.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
