On-site evolution of ultrafine ZnO nanoparticles from hollow metal–organic frameworks for advanced lithium ion battery anodes

Herein, we have successfully realized the on-site evolution of ultrafine ZnO nanoparticles from hollow zeolitic-imidazolate-framework-8 through a simple but efficient plasma treatment. With unique hollow frameworks which decorated with well-dispersed ultrafine ZnO nanoparticles, the h-ZIF-8@ZnO hybrids exhibit enhanced electrochemical performance for Li-ion batteries.
