Ultrafine Ruthenium Clusters Shell‐Embedded Hollow Carbon Spheres as Nanoreactors for Channel Microenvironment‐Modulated Furfural Tandem Hydrogenation

Small 2022, 18, 2201361 DOI: 10.1002/smll.202201361 The title of Figure 4(d–g) is incorrect. The correct title should be: Fig. 4 d) XPS spectrum on Ru 3p3/2 binding energies for the Ru/C catalyst. e, f) Optimized configuration of [email protected]30H14 and [email protected]30H14 models and their corresponding charge density contour plots. g) The differential charge density for the [email protected]30H14 model. The Y-axis of Figure 5e is incorrect. The correct image and the calculation details should refer to the Figure S20 in Section 7.3 of Supporting Information. The authors apologize for any inconvenience caused.
