Synergistic boron-dopants and boron-induced oxygen vacancies in MnO₂ nanosheets to promote electrocatalytic nitrogen reduction

Abstract

The synergistic effect of B-dopants and B-dopant-induced O-vacancies led to the significantly enhanced NRR activity of MnO2 nanosheets with an NH3 yield of 54.2 μg h−1 mg−1 (−0.4 V) and a faradaic efficiency of 16.8% (−0.2 V).

Antibacterial Activity of Manganese Dioxide Nanosheets by ROS-Mediated Pathways and Destroying Membrane Integrity

“…Ultrathin MnO 2 nanosheets, an attractive novel type of 2D material, have attracted widespread attention in energy storage, biological analysis, cell imaging and drug delivery thanks to their large surface area, high near-infrared (NIR) absorbance and good biocompatibility [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Two-dimensional MnO 2 nanosheets exhibit unique photothermal conversion ability due to their inherently thinness, making them excellent photothermal conversion materials for highly effective photothermal therapy (PTT) anti-tumor [ 21 ].…”

Facilitating Oxygen Redox on Manganese Oxide Nanosheets by Tuning Active Species and Oxygen Defects for Zinc‐Air Batteries

“…For example, some researchers induced oxygen defects without modification with other additives, e. g., heating manganese oxides under different temperatures and atmospheres, [52,53] and proton irradiation, [54] while some others created oxygen defects by electrochemical extraction of pre‐inserted cations from a Mn‐based crystal structure [32] . In addition, oxygen defects can also be introduced by doping [38,55] …”
