Preparation of N‐Doped Graphene‐Coated Co<sub>x</sub>Ni<sub>y</sub> Alloy by Laser Induced Co<sub>x</sub>Ni<sub>y</sub>‐MOFs for Detection of Gallic Acid
Abstract Thermal annealing needs protective gas environment, high pyrolysis temperature and long synthesis period. In this work, Co x Ni y /PNG nanocomposites were prepared by laser induced Co x Ni y ‐MOFs at room temperature and in air environment for the first time. In contrast to Co/PNG and Ni/PNG, Co x Ni y /PNG exhibits enhanced electrocatalytic activity for the oxidation of gallic acid. The optimal sensor presents a broad linear range of 0.7–120 μM (R 2 =0.993, with a sensitivity of 0.031 μA/μM) and a low detection limit of 0.13 μM. Meanwhile, the detection results of gallic acid in actual samples by this sensor are satisfactory. This method is simple and feasible and can provide a new idea and method for the rapid preparation of novel nanocatalysts in room temperature and air.
