Summary: This work evaluates a novel metal-free donor-x-acceptor dye (AT-Pyri) for sensitizing TiO2 film photoanodes, demonstrating significant improvement in photocurrent and stability. The addition of triethanolamine (TEOA) to the electrolyte prevents degradation of AT-Pyri, and combining TEOA with methanol further enhances the photoelectrochemical water-splitting activity. The stabilization of the AT-Pyri photoanode is accompanied by a substantial increase in photocurrent and disappearance of transient spikes.
