▎ 摘　　要

Herein, magnetic Ni@graphene composites with core-shell shape were synthesized through thermal annealing of Ni-BTC MOF. On the basis of magnetic core-shell Ni@graphene composites (C-SNi@G), a novel sensing platform has been facilely fabricated using magnetic glassy carbon electrode. The magnetic fabrication of this sensing platform has the advantages of binder-free and easy preparation. The proposed sensor used for the sensing of hydroquinone (HQ) and catechol (CC) exhibits satisfied results. The present work provides a new perspective on the potential applications of MOFs-derived metal/carbon magnetic nanoparticles in sensor fabrication. (C) 2017 Elsevier B.V. All rights reserved.
