Room chemical bath temperature deposition of Mn:FeOOH on BiVO4 photoanode to enhance water oxidation

Review on Synthesis, Modification, Morphology, and Combination of BiVO4-based Catalysts for Photochemistry: Status, Advances, and Perspectives

“…Liu et al improved the CBD process and prepared high-oriented BiVO 4 films on glass substrate with V 2 O 5 as raw material, and studied the relationship between water bath temperature and deposition rate. The Mn-FeOOH cocatalyst was prepared using the chemical bath deposition approach on a BiVO 4 photoanode at room temperature . Mixing Mn elements also results in an increase in the active site, a decrease in the kinetic barrier, a quicker rate of charge transfer, and the potential to function as a passivation layer to prevent electron–hole recombination.…”

“…The Mn-FeOOH cocatalyst was prepared using the chemical bath deposition approach on a BiVO 4 photoanode at room temperature. 81 Mixing Mn elements also results in an increase in the active site, a decrease in the kinetic barrier, a quicker rate of charge transfer, and the potential to function as a passivation layer to prevent electron−hole recombination. According to the data, the photocurrent density of Mn-FeOOH/BiVO 4 is 1.4 mA cm −2 (1.23 vs RHE), which is 2.3 times more than the 0.6 mA cm −2 photocurrent density of the bare BiVO 4 electrode.…”
