摘要：

A cobalt@carbon-dots (Co@C-dots) hybrid material is successfully prepared and well characterized. The hybrid material exhibits intrinsic peroxidase-like activity and can be utilized for the degradation of methylene blue; it shows enhanced catalytic activities compared with bare Co nanoparticles or C-dots. The good catalytic performance of the hybrid material may be attributed to synergistic effects between the Co nanoparticles and C-dots. Furthermore, the catalytic mechanism of the Co@C-dots hybrid material is also studied by using steady-state and time-resolved fluorometric analysis, which reveals that Co@C-dots can effectively decompose H2O2 to produce reactive hydroxyl radicals (OH). These results suggest that the Co@C-dots hybrid material could be a promising material applied for biochemical analysis and water treatment.
