The recycling of environmental wastes to produce value‐added materials is an attractive prospect for both economic and social development. Herein, we use natural crab shell as the templates to synthesize ordered mesoporous carbon nanofiber arrays (OMCNs) based on a combined hard‐templating and surfactant self‐assembly approach. The Brunauer‐Emmett‐Teller surface area of the OMCNs is calculated to be 1200 m 2 g −1 , which is accompanied by good conductivity and a mesoporous structure. The as‐prepared OMCNs exhibit a remarkable electrochemical performance for the detection of malachite green (MG). Differential pulse voltammetry (DPV) reveals that the MG sensor has a wide linear range from 0.1 μM to 22.1 μM with a low detection limit of 0.05 μM. The MG sensor also shows a good stability and excellent anti‐interference, which are investigated by cyclic voltammetry. Furthermore, such an electrochemical sensor is successfully applied for the determination of MG in fishery water samples.
