Construction of High-Nuclear CuxSy Nanocrystalline Catalyst from High-Nuclear Copper Cluster

摘要

A multi-nuclear copper sulfide CuxSy with micro-snowflake structure derived from a known four-core copper cluster C_(28)H_(36)Cl6Cu4N4O5 was fabricated by hydrothermal method in mild condition.The growing process of the snowflake structure experienced from particles,to sheets and flowers,which depended on the reaction time.The prepared materials of high-nuclear copper sulfide in different shapes were taken as catalysts for methylene blue and rhodamine B degradation.The degradation degree of the methylene blue reached up to 97.7% after 13 minutes and it needed 16 minutes for that of the rhodamine B up to 98.2%,which demonstrated that the snowflakes-like CuxSy exhibited excellent photo-catalytic property.Moreover,the high stability of the catalysts was confirmed by cycle experiments and SEM images.
