Back Cover: Optimized Self‐Templating Synthesis Method for Highly Crystalline Hollow Cu2O Nanoboxes (Small Methods 12/2020)

In article number 2000521 by Zheng Chen, Chen Chen, and co-workers, an optimized self-templating synthesis method is developed for preparing highly crystalline hollow Cu2O nanoboxes with relatively small sizes. The evolution process is systematically characterized and the synthesis conditions are carefully controlled. Benefiting from the unique hollow structure, Cu2O nanoboxes can give ≈100% yield for the oxidative homocoupling reaction of terminal alkynes as heterogeneous catalysts under mild conditions.
