Special Issue Information

Dear Colleagues,

It gives us immense pleasure to introduce this Special Issue of Catalysis entitled Recent Trends in Functional Hybrid Nano-Composite Materials and Their Applications for Catalysis. It will deal with aspects of nano-composites that can be exploited for the improvement of various hybrid materials for potential catalysis applications based on transition metal oxide doped or un-doped nano-scale materials on various substrates. Recently, the development of nanotechnology has received much attention in terms of its research and development on the topic of single crystals based on hybrid materials or nanocomposites. In the field of composite materials, doped semiconductor nanostructures have emerged as an exciting prospect due to their remarkable preparation, growth, characteristics, processing, fabrication, development, and potential applications in catalysis. Nanostructure materials have also attracted substantial consideration because of their unique properties and capability for investigating catalytic behaviors, which is simple and feasible for conventional materials coupled with composites in micro-and nanostructures. This Special Issue will deal with advanced and promising developments in the field of nanotechnology on crystalline or amorphous composite materials. Topics will include all features of transition as well as semiconductor material-codoped composites, including their preparation; characterization; processing; fabrication; development; sensing, chemical, physical, catalytical, and biological properties; optical and electronic properties; nano-hybrids; nanotech, biotech, smart-chip, and micro-devices; bio- and nano-medical probes; etc.

Both theoretical and practical features of nano-structure crystalline materials used for nano-science and physicochemical, nano-technological, and medical studies will be covered. This Special Issue is intended to reach a wide audience with diverse backgrounds in the educational sector and is aimed at assembling innovative research and development on hybrid composite materials. It will provide extensive information from dynamic experts in the fields of composite materials, composite sciences, catalysis, and various other technologies. Generally, all significant aspects dealing with the materials, chemistry, physics, biology, technology, health sciences, and engineering of nanoscale composite materials, as well as their extensive catalysis applications, will be considered for publication. Authors are cordially invited to present their novel ideas and recent advanced developments in the form of regular papers or reviews in the field of hybrid composite materials for this Special Issue.

I believe the topic of this Special Issue has yielded innovative routes for the preparation and improvement of continuous changes in the multi-dimensional nano-technological area. It will focus on the cutting-edge nanoscience and nanotechnology of hybrid composite materials. It is expected to guide the preparation of novel nanocomposite materials with special properties, functions, and potential catalysis applications. It will open up possibilities for the solution of environmental, industrial, and ecological problems. I hope that this Special Issue will contribute to providing precious resources to future generations of researchers.

Growing industry and its effluents create a serious environmental concern. Various industrial wastes such as toxic dyes and volatile organic compounds are posing a threat to a clean environment because of their non-biodegradable nature and high chemical stability. In recent years, the degradation of toxic dyes and drugs by photo-catalysts has gained much importance and proved a successful approach to capture light by hybrid photo-catalysts for decomposing toxic organic molecules. This work presents the synthesis of a poly(o-anisidine)-based composite with graphitic carbon nitride and zinc oxide (POA/g-C3N4/ZnO) and its utilization as a photo-catalyst. Various analytical techniques investigated the synthesized photo-catalysts’ chemical structure, crystallinity, and morphology. The degradation of Congo red dye evaluated the efficiency of the photo-catalyst in an aqueous medium under ultraviolet light. It was revealed that the photo-catalytic activity of the synthesized POA/g-C3N4/ZnO composites show 81.43%, 92.28%, and 87.05% degradation. This sustainable composite will be highly beneficial to treat industrial wastewater to make our environment clean. Full article

Catalytic reduction of nitroaromatic compounds (NCs) into corresponding aminoaromatic compounds (ACs) addresses two challenges: enhancing of the manufacture scale of ACs as valuable chemical intermediates and removal of NCs as widespread wastewater pollutants. Among the noble metal catalysts that feature low-temperature activity, chemical stability, and nontoxicity, silver-containing catalysts are attractive as cost-efficient and easily prepared compositions. This paper is devoted to the design and study of efficient and environmentally benign Ag- and CeO2-containing NCs reduction catalysts supported on graphene oxide (GO). The silver- and/or ceria-containing catalysts are synthesized using deposition-precipitation onto GO prepared by oxidative treatment of graphite. The catalysts and support are characterized by XRD, XPS, TGA, N2 sorption, Raman spectroscopy, and UV–VIS spectrometry. The influence of state and the interaction of the active components on catalytic activity is thoroughly estimated in 4-nitrophenol (4-NP) reduction into 4-aminophenol (4-AP) at ambient pressure and room temperature. Nanosized Ag and CeO2 particles with sizes up to 30 and 5 nm, respectively, in the GO structure are obtained. The co-deposition of Ag and CeO2 onto GO promotes the stabilization of silver in the catalyst. The Ag-CeO2/GO catalyst demonstrates superior activity in the synthesized series (kapp of 1.615 and 3.674 min−1 for as-prepared and pre-reduced samples). In addition, the Ag-CeO2/GO catalyst retains good stability and a low leaching degree of the active components that makes these compositions efficient in NCs’ reduction into corresponding ACs.
