Safe etching route of Nb2SnC for the synthesis of two-dimensional Nb2CTx MXene: an electrode material with improved electrochemical performance

In this study, low-temperature synthesis of a Nb2SnC non-MAX phase was carried out via solid-state reaction, and a novel approach was introduced to synthesize 2D Nb2CTx MXenes through selective etching of Sn from Nb2SnC using mild phosphoric acid. Our work provides valuable insights into the field o...
