Abstract

Correction for ‘Hybrid d⁰ and d¹⁰ electronic configurations promote photocatalytic activity of high-entropy oxides for CO₂ conversion and water splitting’ by Jacqueline Hidalgo-Jiménez et al., J. Mater. Chem. A, 2024, 12, 31589–31602, https://doi.org/10.1039/D4TA04689G.

The authors regret that in the original article, the scale bars in Fig. 4b and 5a were incorrect. The authors also regret errors in the orientation of the atomic planes in Fig. 6e. Additionally, the range of the X-axis in Fig. 9a was twice as large as the correct value, and two numbers in Table 3 were incorrectly shown as 12 and 2.95 instead of the correct values, 0.2 and 6.6. These unintentional errors do not affect any other data or the conclusions of the manuscript. The correct Fig. 4–6, 9 and Table 3 are as shown here.

Fig. 4 Homogeneous distribution of elements at the micrometer and nanometer scales in high-entropy oxide TiZrNbTaZnO₁₀. (a) SEM-EDS and (b) STEM-EDS mappings.

Fig. 5 Homogeneous distribution of elements at the atomic scale in high-entropy oxide TiZrNbTaZnO₁₀. (a) Three-dimensional chemical composition distribution and (b) percentage of elements along the sample tip.

Fig. 6 Formation of micro-sized particles with a monoclinic structure in high-entropy oxide TiZrNbTaZnO₁₀. (a and b) SEM micrographs at different magnifications, (c) TEM bright-field micrograph, (d) SAED pattern, and (e) high-resolution image and corresponding fast Fourier transform.

Fig. 9 Enhancement of the photocatalytic activity of high-entropy oxide TiZrNbTaZnO₁₀ compared to TiZrHfNbTaO₁₁ due to the mixed d⁰ and d¹⁰ electronic configuration. CO₂ to CO conversion rate per (a) unit mass and (b) surface area of the two catalysts. H₂ production from water splitting per (c) unit mass and (d) surface area of the two catalysts.
