“…For the Dy 3d XPS profile, the Dy 3d 5/2 and Dy 3d 3/2 peaks were positioned at 1296.6 eV and 1334.5 eV, respectively, with a spin-orbit splitting energy of 37.9 eV, due to the Dy(III) oxidation state [39]. Broad Ho 4d, Er 4d, Tm 4d, and Yb 4d XPS peaks were observed at BEs of 162.4 eV, 168.2 eV, 176.4 eV, and 158.2 eV, respectively [40][41][42][43]. The plot for the 3d 5/2,3/2 spin-orbit splitting energies showed a linear relationship with atomic number from La (# 57) to Dy (#66).…”

Electrochemical coating and recovery by electrodeposition have been invaluably employed for facial thin film fabrication and the recycling of used materials. Herein, we have established a full data set of lanthanide (Ln: La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb) elements electrodeposited on carbon sheets. Cyclic voltammetry was performed for 10 mM Ln(III) ions in a 0.1 M NaClO4 electrolyte over a carbon sheet between +0.5 V and −1.7 V (vs. Ag/AgCl). Amperometry was performed at a given potential to electrodeposit the Ln element on the carbon sheet. Their physicochemical properties were fully investigated by scanning electron microscopy, Fourier-transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. The newly established full data set for Ln(III) ions over carbon electrodes provides useful fundamental information for the development of coating and recovery methods of Ln elements.

Biomass‐based saccharide valorization to produce lactic acid (LaA) via chemocatalysis has emerged as a promising approach to meet the substantial demand of the global LaA market, whereas the manufacture of prominent heterogeneous catalyst is still challenging. Herein, we fabricate a series of heterogeneous rare earth catalysts and indicate that Er supported onto titanium silicate‐1 (TS‐1) exhibits better activity than other rare earth catalysts for glucose transformation towards LaA. Remarkably, coupling Sn with Er onto TS‐1 enabled the sharp increment of LaA yield, and 3Sn15Er/TS‐1 catalyst outperformed other heterogeneous rare earth catalysts as reported to date, giving as high as 82.2% and 76.2% yields of LaA from sorbose and glucose, respectively. The catalyst characterization demonstrated the coexistence of Er2O3 and Sn2Er2O7 on 3Sn15Er/TS‐1 catalyst, both of which contributed to LaA production. Sn doping favored the formation of active particles in smaller size and increased the Lewis acidic sites when compared to single 15Er/TS‐1, thereby promoting the isomerization and retro‐aldol reaction of glucose to C3 intermediates. 3Sn15Er/TS‐1 catalyst also showed universal activity for diverse biomass‐based saccharides. This work might give useful insights to explore heterogeneous rare earth catalysts with superior activity in biomass valorization.
