| 英文摘要 | Preparing metal single-atom materials is currently attracting tremendous attention and remains a significant challenge. herein, we report a novel core-shell strategy to synthesize single-atom materials. in this strategy, metal hydroxides or oxides are coated with polymers, followed by high-temperature pyrolysis and acid leaching, metal single atoms are anchored on the inner wall of hollow nitrogen-doped carbon (cn) materials. by changing metal precursors or polymers, we demonstrate the successful synthesis of different metal single atoms dispersed on cn materials (sa-m/cn, m = fe, co, ni, mn, feco, feni, etc.). interestingly, the obtained sa-fe/cn exhibits much higher catalytic activity for hydroxylation of benzene to phenol than fe nanoparticles/cn (45% vs 5% benzene conversion). first-principle calculations further reveal that the high reactivity originates from the easier formation of activated oxygen species at the single fe site. our methodology provides a convenient route to prepare a variety of metal single-atom materials representing a new class of catalysts. |
