Carbon nanotubes (CNTs) are increasingly preferred as catalysts in chemical industries due to their unique structural, electrical, and mechanical properties. Their high surface area, tunable surface chemistry, and exceptional conductivity make them ideal for catalytic applications. Additionally, their ability to be functionalized with various chemical groups enhances their reactivity and selectivity, enabling efficient and sustainable chemical processes. CNTs also exhibit remarkable thermal and chemical stability, making them suitable for harsh industrial environments. These attributes, combined with their potential for scalability and cost-effectiveness, position CNTs as a superior alternative to traditional catalysts in numerous chemical reactions.
