Abstract
This work investigated electropolymerized (EPD) organic conductive polymers poly-Nile Blue (PNB) and poly-Toluidine Blue (PTB) on fluorine-doped tin oxide (FTO) glass substrates as electrocatalysts for the hydrogen evolution reaction (HER). We investigated the effect of changing the heteroatoms in the pi-conjugated structure of poly-Neutral Red (PNR). UV-vis spectroscopy was used to estimate film thickness. Catalytic activity was quantified by Tafel slope and formal redox potential. PNB and PTB exhibited low current densities and small standard rate constants. Although neither showed highly active catalysts for HER, future directions should continue to pursue structures similar to PNR for HER electrocatalysts.
