摘要
Abstract
Noble metal,has become a research focus in multiple fields due to its empty d electron orbit,small energy gap and diverse coordinations. However,high prices,rare reserves and low utilization have severely restricted their extensive application. So developing excellent functional carriers has become a hot area recently,which makes noble metals be separated from the reaction system easily and recycled effectively and avoids trace residues within the system,reducing environmental pollution. This paper reviewed recent studies of the cheap,non-toxic chitosan green materials which are rich in hydroxyl groups,amino groups and used as noble metal carriers. It also introduced domestic and international representative academic achievements which apply functionlized chitosan in adsorption,catalysis,medicine and other applications. Influences of different surface modification methods on the interaction between noble metals and chitosan carrier have been compared and analyzed. And we outlined the current problems in the noble metal research,such as relatively limited study on morphology and difficulties in controllable large-scale preparation. And its development in biological medicine has been also forecasted.关键词
