Copper immobilized on silk fibroin was successfully prepared and fully characterized using powder X‐ray diffraction, scanning electron microscopy–energy‐dispersive X‐ray spectroscopy, Fourier transform‐infrared, CHN elemental analysis, and inductively coupled plasma‐atomic emission spectroscopy. Catalytic activity of this catalyst was examined in the azide‐alkyne cycloaddition reaction with internal and terminal alkynes at room temperature under mild conditions. The reusability of the heterogeneous supported Cu catalyst was examined four times without significant loss of catalytic activity.

固定在丝素蛋白上的铜纳米颗粒作为绿色可生物降解的催化剂，用于铜催化的叠氮化物末端，内部炔烃的环加成反应

成功地制备了固定在丝素蛋白上的铜，并使用粉末X射线衍射，扫描电子显微镜–能量色散X射线光谱，傅立叶变换红外，CHN元素分析和电感耦合等离子体原子发射光谱对其进行了全面表征。在室温和温和条件下，在与内部和末端炔烃进行叠氮化物-炔烃环加成反应中，检查了该催化剂的催化活性。在不明显损失催化活性的情况下，对非均相负载型Cu催化剂的可重复使用性进行了四次检查。
