摘要: Electrocatalytic properties (towards reduction of bromate in 0.5moldm(-3) H(2)SO(4)) multi-walled carbon nanotubes (CNTs) modified with phosphododecamolybdate (PMo(12)) monolayers have been diagnosed using cyclic voltammetry and amperometry. The ability negatively charged PMo(12)-modified CNTs to attract electrostatically ultra-thin, positively conducting polymer (PEDOT or polypyrrole) structures is explored grow controlled manner hybrid organic-inorganic network electrocatalytic films. Due the presence three-dimensionally distributed CNTs, films' conductivity porosity are improved. systems utilizing polypyrrole, rather than PEDOT, produced fairly higher electroreduction catalytic currents. Comparison also made Nafion-stabilized dispersion inks. latter system characterized by good stability relatively highest sensitivities respect concentration.
