Hollow mesoporous metals have unique potential for catalysis, but their precise synthesis and further elaboration of their structure–performance relationships are still huge challenges. Herein, we report a new synthetic strategy, named the Kirkendall effect in synergistic template (KEST), for the desired preparation of hollow mesoporous palladium–sulfur (h-mesoPdS) alloy nanoparticles. The KEST strategy combines the Kirkendall cavitation synthesis of hollow PdS alloys at the atomic level and the nanocasting growth of a highly ordered mesoporous framework at the mesoscopic level, resulting in one-step solid-phase synthesis of binary h-mesoPdS alloy nanoparticles under ambient conditions. The h-mesoPdS possesses hollow and mesoporous geometry as well as binary PdS alloy composition, which synergistically optimize their electronic structures and energetically adjust the hydrogenation reaction trends. The h-mesoPdS alloy nanoparticles show a remarkable selectivity of 94% for semi-hydrogenating 4-nitrophenylacetylene to industrially important 4-nitrostyrene without hydrogenating the nitro group or over-hydrogenating the alkynyl group. Because of the significant advances in both synthesis and catalysis, this work paves a new route for realizing the targeted synthesis of highly efficient nanomaterials in various applications.
