A multi‐nuclear copper sulfide Cu x S y with micro‐snowflake structure derived from a known four‐core copper cluster C 28 H 36 Cl 6 Cu 4 N 4 O 5 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 Cu x S y exhibited excellent photo‐catalytic property. Moreover, the high stability of the catalysts was confirmed by cycle experiments and SEM images.
