Cu2O-templated strategy for synthesis of definable hollow architectures

Abstract

The template-strategy is one of the most significant techniques for the controllable synthesis of hollow architectures with unique structures, morphologies and properties. In this review, we selectively summarize the general principles of the Cu₂O-templated strategy for the synthesis of definable hollow architectures and cover the recent progress in this area. We elaborate on the use of low-cost Cu₂O templates for synthesizing different types of hollow cages (including copper sulfide, metal oxide, and metal) categorized by their chemical reaction mechanisms, followed by the challenges and perspective on Cu₂O-templated strategy and its potential future directions.
