Photo-Electrochemical Water Splitting Behaviour of ZnO Phthalocyanine and TiO2 Phthalocyanines

Abstract

This describes a study on the photo-electrochemical water splitting behavior of phthalocyanines of ZnO and TiO₂ as photoelectrocatalysts. Here is a breakdown of the key points of the findings in this study. 

Linear Sweep Voltammetry (LSV) studies revealed that the ZnO phthalocyanine photoelectrode showed current density of ~10.8 mA/cm² at 0.8 V (vs. Ag/AgCl) under light illumination and about ~8.8 mA/cm² in the dark. Similarly, the TiO₂ phthalocyanine photoelectrode showed current density of ~10.5 mA/cm² at 0.8 V (vs. Ag/AgCl) under light illumination compared to ~7.8 mA/cm² in the dark.The study's key finding is that the ZnO phthalocyanine demonstrated a higher current density than that of TiO₂ phthalocyanine in both LSV and CA measurements under light illumination.
