Defect-rich and ultrathin nitrogen-doped carbon nanosheets with enhanced peroxidase-like activity for the detection of urease activity and fluoride ion
文献摘要：
Although carbon nanozymes have attracted great interest due to their good biocompatibility,low cost,and high stability,designing high-active carbon nanozymes still faces great challenges.Herein,ultrathin nitrogen-doped carbon nanosheets with rich defects(d-NC)were prepared through a high-temperature annealing process,using potassium chloride and ammonium chloride as templates.Owing to the large specific surface area,rich defects and the high exposure of active sites,the proposed d-NC nanozymes exhibited excellent peroxidase-like activity.The d-NC nanozymes possess maximal reaction velocity and their specific activity is 9.4-fold higher than that of nitrogen-doped carbon nanozymes,indicating that the induced defects can boost the catalytic performance.Benefited from the good peroxidase-like activities of d-NC nanozymes,the colorimetric sensing platforms were constructed for the detection of urease activ-ity and fluoride ion,exhibiting satisfactory stability and selectivity.This study not only offers a way to synthesize carbon nanozymes with improved enzyme-like activities but also broadens their applications in colorimetric biosensing.
