Selenium @ carbon core−shell spheres have been synthesized via a simple one-step hydrothermal carbonization process using sucrose and sodium selenite as precursors. Metal selenide or noble metal, e.g. Ag2Se or Au, can be easily encapsulated into the carbon shell by using the as-prepared Se@C core−sh...
