A novel kind of porous carbon nitride using H-magadiite as the template

A novel kind of porous carbon nitride was prepared by pyrolysis of polymerized ethylenediamine using H-magadiite as the template. This material was characterized by XRD, FT-IR, XPS, and nitrogen sorption at 77 K. The BET surface area, pore volume and the median pore width are 436 m2/g, 0.69 cm3/g and 0.84 nm, respectively, based on the N2 sorption. Using glass carbon electrodes modified by this material, an excellent linear determination range (0.05–0.99 μM) with a low detected concentration limit of 6.9 × 10− 3 μM could be obtained on the determination of differential pulse voltammetries of dopamine in the presence of 400-fold excess of ascorbic acid.
