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‐alkynecycloadditionreaction with internal and terminal alkynes at room temperature under mild
