英文摘要: The three-dimensional porous graphene-mesoporous platinum nanoparticle (3D PGR-MPN) composite is used as solid contact for developing an all-solid-state polymeric membrane Cd2+ ion-selective electrode (Cd2+-ISE). The 3D PGR with MPNs as cross-linking sites can be synthesized by a facile hydrothermal co-assembly method. The obtained 3D PGR-MPN composite is promising for acting as solid contact due to its unique characteristics such as high interfacial area, superior double layer capacitance, excellent conductivity and high hydrophobicity. The ISE exhibits a stable Nernstian response in the range of 10(-8)-10(-4) M and the detection limit is 10(-8.8) M. The 3D PGR-MPN-based Cd2+-ISE shows good potential response and no water layer exists between the polymeric membrane and the 3D PGR-MPN layer. Additionally, the proposed Cd2+-ISE is robust to O-2, CO2 and light interferences. This work provides a versatile method for preparing an effective solid contact to develop a stable and reliable all- solid-state ISE. (C) 2016 Elsevier B.V. All rights reserved.
