Special Issue Information

Dear Colleagues,

Since their discovery in the late 1980s, nanomaterials such as carbon fullerene, carbon nanotubes, and ordered mesoporous materials have opened the door to a revolution in the field of nanotechnology, making them one of the most studied materials due to their unique intrinsic optical, magnetic, electrical, and mechanical features. Nanomaterials, which can be distinguished into several classes on the bases of their dimensionality, including one-dimensional (nanotube, nanowire, nanorods), two-dimensional (nanosheets), and three-dimensional (nanoparticles) types, have, over the last few decades, attracted the attention of scientists in many fields of application, including as heterogeneous catalysts in many industries, such as chemical manufacturing, energy-related applications, and environmental remediation, as well as gas sensors, batteries, and optoelectronic devices, among other biomedical and agricultural applications. This Special Issue on Advanced Nanomaterials for Sustainable Energy, Environmental, and Sensing Applications will attempt to cover the most recent advances in nanostructures, concerning, not only their synthesis and characterization but also their functional and smart properties to be applied in scaling factors, such as grain size, thin film thickness, and porosity in the context of a lattice defect model, nanoceramic thin films, nanoscale superlattices, and mesoporous materials. The articles presented in this Special Issue will cover various topics, ranging from different techniques for synthesis and morphological modification to the preparation of catalytic systems and their application in several areas of interest, such as in catalytic processes and energy, environmental, photochemical, and sensing applications. Therefore, this Special Issue welcomes contributions from all researchers working on nanomaterials, as well as on their characterization, properties, and applications.

The Special Issue will cover, but will not be limited to, the following topics:

  • Advanced synthesis;
  • Smart properties;
  • Characterizations;
  • Multifunctional materials;
  • Energy harvesting/storage devices;
  • Sensors;
  • Highly dispersed metal, metal oxide, or metal sulfide nanoparticles;
  • Heterogeneous catalysis supported by nanoparticle materials;
  • Photochemical properties and applications of nanomaterials;
  • Electrochemical and optical properties of nanomaterials.

It is our pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are welcome.

Tin oxide quantum dots were synthesized in aqueous solution via a simple hydrolysis and oxidation process. The morphology observation showed that the quantum dots had an average grain size of 2.23 nm. The rutile phase SnO2 was confirmed by the structural and compositional characterization. The fluorescence spectroscopy of quantum dots was used to detect the heavy metal ions of Cd2+, Fe3+, Ni2+ and Pb2+, which caused the quenching effect of photoluminescence. The quantum dots showed the response of 2.48 to 100 ppm Ni2+. The prepared SnO2 quantum dots exhibited prospective in the detection of heavy metal ions in contaminated water, including deionized water, deionized water with Fe3+, reclaimed water and sea water. The limit of detection was as low as 0.01 ppm for Ni2+ detection. The first principle calculation based on the density function theory demonstrated the dependence of fluorescence response on the adsorption energy of heavy metal ions as well as ion radius. The mechanism of fluorescence response was discussed based on the interaction between Sn vacancies and Ni2+ ions. A linear correlation of fluorescence emission intensity against Ni2+ concentration was obtained in the logarithmic coordinates. The density of active Sn vacancies was the crucial factor that determined fluorescence response of SnO2 QDs to heavy metal ions. Full article
