Abstract: • Synergistic Co-doping and CoO x cocatalyst enhance BiVO 4 photoanode performance. • Dual modification preserves BiVO 4 ′s structural, optical, and morphological properties. • Photocurrent densities of 4.2 and 4.6 mA/cm2 achieved for water and CH 4 oxidation. This study presents a BiVO 4 (BVO) photoanode modified with cobalt doping and CoO x cocatalyst (Co 10 BVO/CoO x) to enhance photoelectrochemical (PEC) performance, particularly for methane oxidation. While BVO is well-studied for water oxidation, its application in methane conversion remains limited. The synergistic effect of Co-doping and CoO x significantly improves PEC performance, achieving photocurrent densities of 4.2 and 4.6 mA/cm2 at 1.23 V RHE for water and methane oxidation, respectively. Despite maintaining structural, optical, and morphological properties like pristine BVO, Co 10 BVO/CoO x exhibits reduced charge transfer resistance, increased carrier density, and a lower onset potential, enhancing PEC activity. These findings highlight the potential of this dual modification strategy for solar-driven methane valorization and sustainable fuel production. [ABSTRACT FROM AUTHOR]
