Multi-shelled hollow layered double hydroxides with enhanced performance for the oxygen evolution reaction†
Abstract
Hollow materials with a sophisticated structure are promising for various applications with boosted performances and innovative properties. Herein, we report an in situ transformation strategy using multi-layered MOFs as templates to fabricate multi-shelled hollow NiZnCoFe layered double hydroxides (LDHs), which outperformed the double- and single-shelled hollow LDHs and commercial IrO2 in the oxygen evolution reaction.
