In recent years, transition-metal oxides (TMOs) have been long employed for aerobic oxidative desulfurization. However, the inherent bottlenecks, such as low explosion of active sites, limit application bulk TMOs catalyst. this study, V2O5 nanoparticles with oxygen vacancies were prepared in large-scale via facile ball milling strategy adding oxalic acid a reducing agent. The as-prepared catalysts exhibit remarkable sulfur removal oils different initial S-concentrations and substrates....

The state-of-the-art transition-based electrocatalysts in alkaline media generally suffer from unavoidable surface reconstruction during oxygen evolution reaction measurements, leading to the collapse and loss of crystalline matrix. Low potential discharge offers a gentle way for thus realizes manipulation real active site. Nevertheless, absence fundamental understanding focus on this region renders functional phase, either or amorphous matrix, controllable still undecidable. Herein, we...
The structure and properties of the graphene-Al interface change significantly when defects are present in graphene.
