主 题：single-atom catalysts electrochemical sensor layered double hydroxides nitrogen-doped graphene synergistic effect
摘 要：The development of novel single-atom catalysts is important for highly efficient electrochemical catalysis and *** this work,a novel Pt single atoms(SAs)supported on Ni_(6)Co_(1)layered double hydroxides/nitrogen-doped graphene(Pt_(1)/Ni_(6)Co_(1)LDHs/NG)was constructed for electrochemical enzyme-free catalysis and sensing towards *** loading of Pt single atoms increases with doping of Co atoms that generate more anchoring sites for Pt *** resulting Pt_(1)/Ni_(6)Co_(1)LDHs/NG exhibits low oxidative potential of 0.440 V with high sensitivity of 273.78μA·mM^(−1)·cm^(−2)toward glucose,which are 85 mV lower and 15 times higher than those of Ni(OH)_(2),***_(1)/Ni_(6)Co_(1)LDHs/NG also shows excellent selectivity and great stability during 5-week *** and experimental results show that the boosted performance of Pt_(1)/Ni_(6)Co_(1)LDHs/NG originates from its stronger binding energy with glucose and the synergistic effect of Pt SAs,Co doping,and *** work provides a general strategy of designing highly active SACs for extending their application in electrochemical sensing.
