Article Description

The co-splitting of water (H2O) and carbon dioxide (CO2) into hydrocarbons as a fuel is one of the major challenges in the electrochemical method for the energy and environmental applications. To overcome the challenge, the scientific research shows a great attention on the design and development of novel electrocatalysts. Herein, the perovskite type La0.5Sr1.5MnO4 coated TiO2 electrocatalyst was developed by the facile chemical co-precipitation, electrochemical anodization and cathodization methods. The crystal structure, morphology and the presence of elemental composition were determined by XRD, SEM, TEM and XPS techniques. Further, the electrochemical studies were investigated to see the performance of La0.5Sr1.5MnO4 perovskite coated TiO2 in 1M KOH using linear sweep voltammetry, chronoamperometry and impedance techniques. The electrocatalyst exhibited the onset potentials of water splitting (1.3 V) and CO2 splitting (-1.7 V), and performed the stability for 14 hrs.
