Large scale and controllable preparation of W2C nanorods or WC nanodots with peroxidase-like catalytic activity

摘要

W2C nanorods or WC nanodots are prepared via an easy,shape-controllable and large-scale preparation technique.Results reveal that each of the W2C nanorods and WC nanodots has a peroxidase-like activity.Besides,the peroxidase-like activity of W2C is the first time to be demonstrated.The catalytic efficiency of W2C nanorods is much higher than that of WC nanodots and chemical condition range of W2C can be wider than that of WC,which indicates that W2C is likely to be used as artificial mimetic peroxidase or in-situ amplified colorimetric immunoassay.
