Special Issue Information

Dear Colleagues,

In the last few decades, there has been great and unpredicted progress in the synthesis, characterization, and potential applications of semiconductor nanomaterials. Semiconductor nanomaterials have shown their applicability for a range of technologies because of their enhanced and improved physical, chemical, and functional properties. Such nanomaterials are used for a variety of potential applications, from electronics to sensor devices to energy, environmental remediation, medical fields, and so on. Over the past decades, the physics and chemistry of semiconductor nanomaterials have been emerging topics in nanoscience and nanotechnology, as such nanomaterials have shown extraordinary and advantageous properties and hence applications based thereon. The rapid development of semiconductor nanomaterials provides the possibility of designing better and unique devices with outstanding properties.

This Special Issue is a timely approach to survey recent progress in the area of semiconductor nanomaterials synthesis, properties, and applications. The articles presented in this Special Issue will cover various topics, ranging from semiconductor nanomaterials preparation, engineering, functionalization, and their various applications, such as sensors (chemical, biological, gas, etc.), environmental remediation, biological labeling, fuel cell, electrocatalysis, catalysis, photocatalysis, electronic devices, bio-applications of nanomaterials, and so on. Certainly, the coverage is not complete, but it is our intension that this Special Issue will offer a unique glimpse of what has been achieved and what remains to be explored in functional nanomaterials.

This Special Issue will cover topics including but not limited to:

- Synthesis and characterizations of semiconductor nanomaterials;

- Sensors (bio, chemical, gas, optical, etc.);

- Photocatalysis;

- Catalysis;

- Environmental remediation;

- Electronic devices;

- Energy devices;

- Bio-applications of functional nanomaterials;

- Theoretical studies;

- etc.

It is our pleasure to invite you to submit review articles, original papers, and communications for this Special Issue "Semiconductor Nanomaterials: Growth, Properties, and Applications".

Photocatalytic materials and semiconductors of appropriate structural and morphological architectures as well as energy band gaps are materials needed for mitigating current environmental problems, as these materials have the ability to exploit the full spectrum of solar light in several applications. Thus, constructing a Z-scheme heterojunction is an ideal approach to overcoming the limitations of a single component or traditional heterogeneous catalysts for the competent removal of organic chemicals present in wastewater, to mention just one of the areas of application. A Z-scheme catalyst possesses many attributes, including enhanced light-harvesting capacity, strong redox ability and different oxidation and reduction positions. In the present work, a novel ternary Z-scheme photocatalyst, i.e., Bi2WO6/C-dots/TiO2, has been prepared by a facile chemical wet technique. The prepared solar light-driven Z-scheme composite was characterized by many analytical and spectroscopic practices, including powder X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), N2 adsorption–desorption isotherm, Fourier-transform infrared spectroscopy (FT-IR), photoluminescence (PL) and UV-vis diffuse reflectance spectroscopy (DRS). The photocatalytic activity of the Bi2WO6/C-dots/TiO2 composite was evaluated by studying the degradation of fluoroquinolone drug, levofloxacin under solar light irradiation. Almost complete (99%) decomposition of the levofloxacin drug was observed in 90 min of sunlight irradiation. The effect of catalyst loading, initial substrate concentration and pH of the reaction was also optimized. The photocatalytic activity of the prepared catalyst was also compared with that of bare Bi2WO6, TiO2 and TiO2/C-dots under optimized conditions. Scavenger radical trap studies and terephthalic acid (TPA) fluorescence technique were done to understand the role of the photo-induced active radical ions that witnessed the decomposition of levofloxacin. Based on these studies, the plausible degradation trail of levofloxacin was proposed and was further supported by LC-MS analysis. Full article
