Recently metal-decorated carbon nanotubes (CNTs) have attracted considerable interests from multiple disciplines due to their interesting catalytic, electrical, and mechanical properties as well as the significance in material sciences. 10 Ideally, Pd–CNT could offer conspicuous advantages of heterogeneous catalysis 11 while retaining high catalytic activity of NPs. Thus, such catalysts would be highly desirable from the perspectives of transition metal catalysis, green ...
