The Cover Feature shows a selective conversion of nitroarenes to aminoarenes via a steered adsorption from tantalates‐based solid acid′s intrinsic proton. In their Full Paper, Y. Ma et al. have investigated roles of the intrinsic protons from Brønsted solid acid support with the prepared series of alkali‐resistant tantalate‐supported silver catalysts (Ag/M x H 2‐X Ta 2 O 6 , M=H, Li, Na, K, Sr) for the reaction of catalytic conversion of nitroarenes to aminoarenes. They proposed that these intrinsic protons can steer adsorption of ‐NO 2 group through H‐bonding and electrostatic attraction to afford a selective reduction. These intrinsic protons also directly participate in the formation of products and they are responsible for the excellent reusability via an exchange and protonating with Ag NPs. This work is aimed at guiding a novel design of catalyst based on Brønsted solid acids for H‐participating reactions. More information can be found in the Full Paper by Y. Ma et al.
