Abstract

Significant efforts have been made in the recent times towards the synthesis of sustainable photocatalyst that are both eco-friendly and cost effective in terms of reduction of CO₂. The outstanding properties exerted by bismuth, as BiVO₄ in specific with respect to its highly facilitative band gap of 2.4 eV has been gaining considerate attention. In the present study, attempts have been made to dope WO₃ onto BiVO₄ as a means of reducing the recombination rates thereby facilitating the CO₂ process. The characterisation results are indicative of the excellent crystallographic properties exerted by the material in addition to the supremacy over stand-alone BiVO₄ (0.97 mA/cm²) and WO₃ (0.23 mA/cm²) with respect to photocurrent response (1.69 mA/cm²). The catalyst survived 6 cycles of usage, indicative of its environmental and economic upper hand in addition to the greater rates of CO and H₂ evolution (29.14 μmolg⁻¹h⁻¹ & 9.24
