摘要：
Hollow-structured polyhedral nanostructures of AgI nanoboxes and cube-tetrapod Ag/AgI cages have been fabricated through the controlled reaction of I- ions with nanocubes and cube-tetrapods of AgCl based on the principle of the Kirkendall effect. The Ag-0 nanodomains in the source nanoparticles of AgCl:Ag are preserved in the final hollow Ag/AgI cages during the chemical conversion of AgCl to AgI. The obtained hollow cube-tetrapod Ag/AgI nanostructures exhibited enhanced light absorption in the visible region and photocatalytic performance towards hydrogen evolution from water reduction and decomposition of organic pollutants, owing to the contribution of the surface plasmon resonance (SPR) effect of silver nanoparticles (nanodomains). The present versatile route can be generalized to the preparation of other inorganic functional materials with hollow interiors for different applications.
