Abstract

Abstract: A multi‐nuclear copper sulfide Cux Sy with micro‐snowflake structure derived from a known four‐core copper cluster C28 H36 Cl6 Cu4 N4 O5 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 Cux Sy exhibited excellent photo‐catalytic property. Moreover, the high stability of the catalysts was confirmed by cycle experiments and SEM images.

The degradation degree of the methylene blue reached up to 97.7% after 13 minutes, it needed 16 minutes for that of the rhodamine B up to 98.2% and the mixed dyes were degraded colorless after 8 minutes, which demonstrated that the snowflakes‐like Cux Sy exhibited excellent photo‐catalytic property.
