| 中文摘要 | methylene blue-intercalated a-zirconium phosphate (mbzrp) micro particles in deionized water were deposited onto the surface of graphite powder to prepare graphite powder-supported mbzrp, which was subsequently dispersed into methyltrimethoxysilane-derived gels to yield a conductive composite. the composite was used as electrode material to fabricate a surface-renewable, rigid, leak-free carbon ceramic composite electrode, bulk-modified with methylene blue (mb). in the configuration, alpha-zirconium phosphate was employed as a solid host for mb, which acted as a catalyst. graphite powder ensured conductivity by percolation, the silicate provided a rigid porous backbone and the methyl groups endowed hydrophobicity and thus limited the wetting section of the modified electrode. peak currents of the mbzrp-modified electrode were surface-confined at low scan rates but diffusion-controlled at high scan rates. square-wave voltammetric study revealed that mbzrp immobilized in carbon ceramic matrix presented a two-electron, three-proton redox process in acidic aqueous solution with ph ranged from 0.44 to 2.94. in addition, the chemically modified electrode showed an electrocatalytic activity toward nitrite reduction at +0.15 v (vs. ag/agcl) in acidic aqueous solution (ph=0.44). the linear range and detection limit are 1 x 10(-6)-4 x 10(-3) mol l-1 and 1.5 x 10(-7) mol l-1, respectively. |
