General Synthesis and Gas‐Sensing Properties of Multiple‐Shell Metal Oxide Hollow Microspheres

Abstract

A sphere of many coats: A facile sequential templating process for the general preparation of metal oxide hollow microspheres with multiple shells (red), such as α-Fe2O3, Co3O4, NiO, CuO, ZnO, and ZnFe2O4, may open up new opportunities for preparing advanced materials based on complex hollow structures with multipurpose applications.
