Abstract The Li metal is an ideal anode material owing to its high theoretical specific capacity and low electrode potential. However, reactivity dendritic growth in carbonate-based electrolytes limit application. To address these issues, we propose a novel surface modification technique using heptafluorobutyric acid. In-situ spontaneous reaction between the organic acid generates lithiophilic interface of lithium heptafluorobutyrate for dendrite-free uniform deposition, which significantly...
Increasing the density of surface Fe–N 4 sites in Fe–N–C materials is pivotal for enhancing kinetics oxygen reduction reaction (ORR) proton exchange membrane fuel cells (PEMFCs).
To achieve the Fe-N-C materials with both high activity and durability in proton exchange membrane fuel cells, attack of free radicals on Fe-N4 sites must be overcome. Herein, we report a strategy to effectively eliminate at source mitigate degradation by anchoring CeO2 nanoparticles as scavengers adjacent (Scaad-CeO2 ) sites. Radicals such ⋅OH HO2 ⋅ that form can instantaneously eliminated , which shortens survival time regional space their damage. As result, Fe-NC/Scaad-CeO2 achieved ∼80 %...
Abstract The direct oxidation of methane to methanol under mild conditions is challenging owing its inadequate activity and low selectivity. A key objective improving the selective first carbon-hydrogen bond methane, while inhibiting remaining bonds ensure high yield selectivity methanol. Here we design ultrathin Pd x Au y nanosheets revealed a volcano-type relationship between binding strength hydroxyl radical on catalyst surface catalytic performance using experimental density functional...
