Year: 2024
Type: article
Abstract: Thermal annealing needs protective gas environment, high pyrolysis temperature and long synthesis period. In this work, CoxNiy/PNG nanocomposites were prepared by laser induced CoxNiy‐MOFs at room temperature and in air environment for the first time. In contrast to Co/PNG and Ni/PNG, CoxNiy/PNG exhibits enhanced electrocatalytic activity for the oxidation of gallic acid. The optimal sensor presents a broad linear range of 0.7–120 μM (R2=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.
