Electric‐driven conversion of carbon dioxide (CO2) to carbon monoxide (CO) under mild reaction conditions offers a promising approach to mitigate the greenhouse effect and the energy crisis. The surface engineering is believed to be one of the prospective methods for enhancing the electrocatalytic activity of CO2 reduction. Herein, the hydroxyl (OH) groups were successfully introduced to cadmium nanosheets to form cadmium and cadmium hydroxide nanocomposites (i.e. Cd/Cd(OH)2 nanosheets) via a facile two‐step method. The as‐prepared Cd/Cd(OH)2/CP (CP indicates carbon paper) electrode displays excellent electrocatalytic activity for CO2 reduction to produce CO. The Faradaic efficiency of CO reaches 98.3% and the current density achieves 23.8 mA cm‐2 at ‐2.0 V vs. Ag/Ag+ in a CO2‐saturated 30 wt% 1‐butyl‐3‐methylimidazole hexafluorophosphate ([Bmim]PF6)‐65 wt% acetonitrile (CH3CN)‐5 wt% water (H2O) electrolyte. And the CO partial current density can reach up to 71.6 mA cm‐2 with the CO Faradaic efficiency of more than 85% at ‐2.3 V vs. Ag/Ag+, which stands out against Cd/CP, Cd(OH)2/CP, and Cd/CdO/CP electrodes. The excellent electrocatalytic performance of the Cd/Cd(OH)2/CP electrode can be attributed to its unique structural properties, suitable OH groups, perfect interaction with electrolyte, abundant active sites and fast electron transfer rate.

“…Various improper sources of such ferromagnetic behavior (instrumental artifacts, alien magnetic impurities, etc.) have become well documented, but they are rarely taken into account when ferromagnetism of initially non-magnetic bulk materials at room temperature are reported [1][2][3]. From the single element material (graphite) to several covalently bonded non-magnetic compounds (for example, oxides, nitrides, selenides, etc.…”

Mixed-phase TiN x -TiO y nanoparticles with an average particlesize of 27-120 nm were prepared by the levitationjet generator through condensation of Ti metal vapor in inert gas flow with gaseous nitrogen/air additive. The nanoparticles were characterized by Scanning electron microscopy, X-ray diffraction, Ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, and Vibrating sample magnetometry. Room-temperature ferromagnetism with a maximum magnetization of up to 0.14 emu/g was discovered in the nanoparticles. The observed ferromagnetic ordering was related to the defect Ti-N-O structures at the interfaces between crystal phases. This suggestion is in good correlation with data obtained during spectroscopic studies. All the results demonstrate that the predominant role of the nitrogen and oxygen vacancies at the interfaces between titanium nitride, anatase, rutile, as well as the other mixed Ti-N-O phases contribute to the evolution of the room-temperature ferromagnetism. The maximum saturation magnetization of nanoparticles was extremely dependent on the N/O ratio, and area of peaks core-levels N 1s and O 1s. For the first time, an unknown phenomenonof a temporary "turn-off" effect of magnetization in hysteresis loops of some mixed-phase nanoparticles was discovered. The obtained results could be used in the search for new spintronic materials.
