Polyanilines (PANIs) are easily prepared from anilines via oxidative polymerization reactions and widely used as supports for nano metal catalysts due to their coordination with metals. Compared to inorganic supports, the nano metals on PANIs are firmly anchored, preventing loss during reactions. Additionally, the chemical features of PANIs can be adjusted, providing tunable catalytic activities. This review aims to summarize recent advances and provide a perspective on PANIs-supported nano metal catalysts.
Polyanilines (PANIs) can be easily prepared from the available and cheap anilines via the oxidative poly-merization reactions. Owing to the coordination of nitrogen in the material with metals, PANIs are widely used as the support of nano metal catalysts. In comparison with inorganic supports, the nano metals on PANIs were firmly anchored via the coordination bond so that they are not easily to lose during the re-action process. Moreover, since PANIs are versatile materials and their chemical features can be adjusted by introducing functional groups onto the monomers, the catalytic activities of the prepared catalysts are tunable. During the past decade, PANIs-supported nano metal catalysts have been widely applied in a variety of coupling reactions. This review aims to summarize the recent advances and give a perspective.(c) 2022 Published by Elsevier B.V. on behalf of Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
