▎ 摘　　要

Herein, a universal laser-assisted growth method is applied for supporting transition metal nanoparticles on three dimensional graphene (3D GR). Different from chemical/thermal reduction or deposition methods, all experimental steps could be achieved at room temperature and in air environment using laser irradiation as the energy source and metal-organic frameworks (MOFs) as precursors. Another unique property is that metal nanoparticle/3D GR could act as an electrode for a nonenzymatic glucose sensor. Due to the porous nature and catalytic properties of the metal nanoparticles, metal nanoparticle/3D GR shows a high direct oxidation activity toward glucose in alkaline solution. Co/3D GR achieves a linear range of 10-3020 mu M and a limit of detection of 2.7 mu M and is selective to common interferences, indicating its promising application for glucose determination. Such an easy, facile, and universal method could be extended for the rapid preparation of metal particle/GR and other electrochemical applications.
