Description

Application

• Chitosan-based film supported copper nanoparticles: A potential and reusable catalyst for the reduction of aromatic nitro compounds.: This study investigates the application of copper(II) chloride dihydrate in the development of chitosan-based films embedded with copper nanoparticles, which serve as an effective and reusable catalyst for the reduction of aromatic nitro compounds. The process highlights the potential of copper(II) chloride dihydrate in catalytic applications within analytical chemistry, providing a sustainable approach to chemical reactions (de Souza JF et al., 2017).
