Corrigendum to “Spinel-covered interlayer MgO enhances the performance of BiVO₄ photocatalytic ammonia synthesis” [Appl. Catal. B Environ. Energy 344 (2024) 123670] (Applied Catalysis B: Environment and Energy (2024) 344, (S0926337323013139), (10.1016/j.apcatb.2023.123670))>

The authors regret that Fig. 5d is incorrect in the original manuscript. ABPE has an error in the conversion from current-voltage curve. The ABPE value is calculated from the current-voltage curve with the following formula: [Formula presented] |J| is the current density (mA cm⁻²), V_th is the theoretical water decomposition voltage (1.23 V vs. RHE), V_bias is the bias voltage relative to the reversible hydrogen electrode, P is the light intensity of AM 1.5 G (100 mV cm⁻²). During the current-voltage tests, |J| and V_bias were obtained using Ag/AgCl (3.5 M KCl) electrode as the reference electrode. The bias voltage corresponding to Ag/AgCl should be converted to the bias voltage corresponding to the reversible hydrogen electrode during the calculation of ABPE, because this step was missing, which led to an error in the transverse (V_bias). The bias voltage is involved in the ABPE calculation process, so it eventually leads to an error in the ABPE value. The modified diagram is shown below: To assess the efficiency of the electrical energy being subtracted, ABPE was used as shown in Fig. 5d. MnCo₂O₄/MgO/BiVO₄, and ZnCo₂O₄/MgO/BiVO₄ achieve the highest efficiencies of 1.42% and 2.01% at 0.53 V vs. RHE, respectively. MgO/BiVO₄ can only obtain 0.64% at 0.74 V vs. RHE, and BiVO₄ can only obtain 0.3% at 0.85 V vs. RHE. The authors would like to apologise for any inconvenience caused.
