| 英文摘要 | Developing single-atom catalysts with porous micro-/nanostructures for high active-site accessibility is of great significance but still remains a challenge. herein, we for the first time report a novel template-free preassembly strategy to fabricate porous hollow graphitic carbonitride spheres with single cu atoms mounted via thermal polymerization of supramolecular preassemblies composed of a melamine cu complex and cyanuric acid. atomically dispersed cu-n-3 moieties were unambiguously confirmed by spherical aberration correction electron microscopy and extended x-ray absorption fine structure spectroscopy. more importantly, this material exhibits outstanding catalytic performance for selective oxidation of benzene to phenol at room temperature, especially showing phenol selectivity (90.6 vs 64.2%) and stability much higher than those of the supported cu nanoparticles alone, originating from the isolated unique cu-n-3 sites in the porous hollow structure. an 86% conversion of benzene, with an unexpectedly high phenol selectivity of 96.7% at 60 degrees c for 12 h, has been achieved, suggesting a great potential for practical applications. this work paves a new way to fabricate a variety of single-atom catalysts with diverse graphitic carbonitride architectures. |
