The accelerating use of organic dyes in various industries has led to a surge water pollution, especially from non-biodegradable dye effluents discharged into resources. This study addresses the critical issue catalyzing reduction two prevalent dyes, methylene blue (MB) and rhodamine-B (RhB), using multiwalled carbon nanotube-cobalt ferrite (MWCNT-CF) nanocomposite. synthesized nanocomposite demonstrates exceptional catalytic activity, stability, recyclability. Conventional methods for...
The scientific community believes that high-quality, bulk layered, semiconducting single crystals are crucial for producing two-dimensional (2D) nanosheets. This has a significant impact on current cutting-edge science in the development of next-generation electrical and optoelectronic devices. To meet this ever-increasing demand, efforts have been made to manufacture high-quality SnS2 utilizing low-cost CVT (chemical vapor transportation) technology, which allows large-scale crystal...
