The Front Cover shows Pd‐Zn alloy nanoparticles encapsulated in mesoporous silica (Pd‐Zn@MS) to demonstrate confinement effects for the highly selective semi‐hydrogenation of phenylacetylene. In their Full Paper, Z. Li, M. Hu et al. explain that Pd‐Zn@MS prepared via annealing Pd NPs@ZIF‐8 in a reducing atmosphere and the as‐obtained Pd‐Zn@MS achieves up to 95% of conversion rate and 92% of selectivity. The mesoporous silica exhibits a steric hindrance effect for the size of the reactant molecules and the Pd‐Zn alloy nanoparticles show high selectivity for the target product styrene. This work provides a new idea for the selective hydrogenation of phenylacetylene and the process of limited‐area catalysis. More information can be found in the Full Paper by Z. Li, M. Hu et al.
