Abstract
Correction for ‘Photoelectrochemical reduction of nitrates at the illuminated p-GaInP2 photoelectrode’ by Heli Wang et al., Energy Environ. Sci., 2013, 6, 1802–1805.
The previous IPCE spectrum (Fig. 4) was incorrect, due to our old instrument being out of calibration. With a new setup constructed, calibration was carried out by putting a reference cell inside the working glass cell to get rid of the effect of the glass window. A 375 nm filter was placed in front of the glass cell. IPCE was calculated based on the quantum efficiency of the reference cell.
Accordingly, Fig. 4 in our paper should be replaced with the following:
 | ||
| Fig. 4 IPCE for the p-GaInP2 electrode at −1 V (vs. Ag/AgCl) in pH 1 NH4NO3 solution at room temperature. IPCE is over 60% until 620 nm; below 2% at 680 nm. | ||
