NANOMATERIALS IN CHEMICAL ENGINEERING: SYNTHESIS, CHARACTERIZATION, AND INDUSTRIAL APPLICATIONS IN CATALYSIS

Abstract

Nanomaterials are deemed novel materials that have essentially changed the field of chemical engineering, accounting for their unique physicochemical properties conferred via high surface area to volume ratio, enhanced reactivity, and mechanical strength. These properties of nanomaterials led to advanced synthesis and characterization studies in catalysis, greatly enhancing the efficiency, selectivity, and sustainability of industrial applications. The study herein investigates various synthesis techniques: physical, chemical, and biological-forfabricating nanomaterials with specified properties. Characterization of the nanomaterials with the help of advanced techniques-e.g., scanning electron microscopy, X-ray diffraction (XRD), Spectroscopy-is very important for understanding their various structural and functional properties. Nanocatalysts based on metals, metal oxides, carbon, and hybrids showed tremendous potential in petrochemical, pharmaceutical, and environmental applications, more so in their industrial catalysis. Nevertheless, such big barriers to widespread adoption include toxicity, stability, and cost-effectiveness. Experimental studies indicated that nanostructured catalysts exhibit greater catalytic activity, turnover frequency, and durability when compared with conventional catalysts. This exploration inspires the need to conduct extensive research into green synthesis and upscaling methods that can serve to bridge the gap between laboratory-scale research and industrial applications. Coming advancements in nanomaterials will be in the way of next-generation catalytic processes-more sustainable and far more efficient in chemical engineering.
