Synthesis and photoelectrochemical performance of Co doped <scp>SrTiO₃</scp> nanostructures photoanode

It is pertinent to realize that scientific research indicates the most promising method for producing H2 photo electrochemical water splitting through a anode. Cobalt-doped SrTiO3 (Co-SrTiO3) composite nanostructures were created in this study via hydrothermal synthesis. The impact of cobalt concentration change on Co-SrTiO3 has been identified using morphological, structural, and research. Surface morphology pure nanoparticles SEM TEM reveals particles are intermittently agglomerated. inclusion Cobalt lowered particle size 23 nm than (41 nm). In addition, peak profile influenced by cubic phase also from x-ray diffraction analysis. purity composition materials revealed XPS composite's produced best charge transfer recombination capabilities at 3% Co doping, according chemical impedance (EIS) spectroscopy. At 0.2 V applied potential, obtained Co-doped photoanode system displays photocurrent density around 3.45 mA/cm2. outcomes show application photoelectrochemical splitting.
