Figure 2From: One-pot synthesis of poly (3,4-ethylenedioxythiophene)-Pt nanoparticle composite and its application to electrochemical H2O2 sensorUV-vis spectra. UV-vis spectra of the solution containing PEDOT/PtNP composite prepared (a) without and (b) with UV-irradiation for various periods. The absorbances in the range from 400 to 1200 nm are enlarged for both samples and shown as insets in (a) and (b).Back to article page
