Synthesis of noble metal-free monodisperse high-entropy oxides hollow nanocubes libraries via a coordination etching strategy
High-entropy oxides (HEOs) consist of multiple principal metal cations and oxygen anions, which enhances compositional versatility and promotes the emergence of atypical properties within oxide materials. Nonetheless, precisely shaping HEOs in hollow nanostructures remains a significant challenge due to the disparate nucleation and growth kinetics of the various metal oxide compositions in HEOs. Herein, we present a strategy for the synthesis of multicomponent hollow nanocubes HEOs libraries from ternary to octonary. We utilized a template-assisted route inspired by coordinating etching and integrating thermal treatment to synthesize HEOs hollow nanocubes through the selection of coordinating etchant and optimization of the reaction conditions. This approach demonstrates the potential for precisely designing high-quality HEOs hollow nanocubes with diverse compositions at low temperature, with promising prospects for various applications.
