Electrocatalytic reduction of bromate based on Pd nanoparticles uniformly anchored on polyaniline/SBA-15

These results show that Pd-NPs/PANI/SBA-15 is effective for electrocatalytic reduction of BrO3− and has great potential for the fabrication of BrO3− electrochemical sensor

Scholarcy highlights

  • A nano-composite electrocatalyst of Pd nanoparticles anchored on polyaniline supported by mesoporous SBA-15, was synthesized using an in situ chemical method
  • Transmission electron microscopy showed that the Pd-NPs were homogeneously dispersed
  • It is proposed that the bromate ions diffuse to the Pd-NPs active sites and the electrocatalytic reduction occurred with the H+ doped in PANI
  • Continuous cyclic voltammetry for 200 cycles proved that Pd-NPs/PANI/SBA-15 had excellent electrocatalytic stability
  • These results show that Pd-NPs/PANI/SBA-15 is effective for electrocatalytic reduction of BrO3− and has great potential for the fabrication of BrO3− electrochemical sensor
