Abstract
Abstract Niobium nitrides possess superconductivity and stable chemical stability, which render them desirable candidates for energy storage. Therefore, they deserve exploration for potential energy storage applications. Here we report on the synthesis of 2D Nb 4 N 5 nanosheets by ammonization of NbS 2 nanosheets as templates at 700 °C. The obtained 2D Nb 4 N 5 nanosheets retain their hexagon shape and display a porous structure with a pore size of 3.716 nm. These 2D Nb 4 N 5 nanosheets exhibit capacitor behavior as electrode materials for energy storage. This study opens a new avenue in synthesizing 2D materials based on 2D templates.
