摘要：

Pb2+ probes play an important part in environments and human health. We developed a new free-standing electrochemical probe by 3D printing UiO-66-NH2 with @rGO. This free-standing fiber electrochemical sensor exhibited good structural stability and Pb2+ sensing performance with enhanced conductivity. This MOFs-based hybrid probe showed an excellent sensing sensitivity for Pb2+ with a very low detection limit of 0.041 mu M, significantly lower than the standard for Pb2+ in drinking water as a result of the porous structure of UiO-66-NH2 and the good conductivity of rGO. This study highlighted a simple strategy for MOFs-based hybrid sensor formation and accelerated the MOFs-based materials for Pb2+ electrochemical detection in future practical applications.
