A sign of nobility! The cover picture shows high performance catalysis of multi‐walled carbon nanotubes (MWCNTs)–Fe 3 O 4 loaded with Pd nanoparticles in the carbonylative Sonogashira coupling reaction and catalytic hydrodegradation of methylene blue (MB). In their Communication on p. 1868 ff., S. L. Yang, W.‐G. Song et al. develop an effective method for directly loading noble metals onto magnetic MWCNTs. Through an in situ galvanic replacement reaction between Cu nanoparticles and noble metal ions, a series of MWCNTs–Fe 3 O 4 –noble metal (Pd, Pt, Au) composites with uniform dispersion, small metal particle size, and tunable loading are obtained. The noble metal nanoparticles are within a few nanometers in size and are highly dispersed, which is beneficial for catalytic applications. This method offers a new way to prepare noble metal loaded magnetic MWCNT composite catalysts. rMB=Reduced MB.
