The synthesis of novel nanoparticles: transition from hollow to groove via self-template sacrifice strategy

A novel self-template sacrifice strategy was reported to prepare highly ordered mesoporous carbon (OMC) nanoparticles with idiographic hollow and unique groove structure. Besides, we successfully accomplished multi-morphology interconversion by simply regulating initial reaction temperature and the concentration of hydrochloric acid, and the particle sizes could be easily tuned from 700 to 190 nm. Meaningfully, a “pyrolysis-sagging” mechanism was further proposed for the comprehension of the groove structure, which provided a brand-new and oversimplified soft template principal for the synthesis of OMC with novel morphology. Moreover, the self-template sacrifice strategy was rationalized through a simplified replenishment of the nucleation and growth stages as an extension. The as synthesized materials were used as carriers for furosemide to evaluate the drug adsorption and release performance, endowing them with significant prospect in the field of biomedicine.
