Here, a new approach to further improve graphdiyne (GDY) based materials by using benzyl disulfide (BDS) as the sulfur source is demonstrated. The S radicals, generated from the homolysis of BDS, can react with the acetylenic bonds and be well confined in the triangle-like pores of GDY, forming S-GDY. The as-prepared S-GDY, which possesses numerous heteroatom defects and active sites, is suitable for applications in many electronic devices, such as lithium ion batteries (LIBs). As expected, the assembled LIBs based on S-GDY displayed improved electrochemical properties, including larger capacity and superior rate capability. |
