A gradient current collector (GCC) can encourage preferential Li metal deposition on the more lithiophilic/conductive bottom of 3D anodes, enhancing the reversibility of the battery. However, as the deposition proceeds, the reduction of lithophilicity/conductivity easily causes the disturbance of Li+ flux. Herein, a brand‐new bicomponent‐bidirectional gradient current collector (BGCC) is proposed...
Ethanol Oxidation Reaction
In article number 2203506, Xinlong Tian and co‐workers prepare 2D ternary Pd3Pt1Rh0.1 nanorings with efficient ethanol oxidation reaction performance via a facile one‐pot solvothermal approach, and systematic studies are carried out to reveal the mechanisms of the enhanced performance and C–C bond selectivity. The density functional theory calculations show that the introduction...
Ethanol as a fuel for direct ethanol fuel cells (DEFCs) has the advantages of being highly energetic, environmentally friendly, and low−cost, while the slow anodic ethanol oxidation reaction (EOR), intermediate poisoning effect, and incomplete oxidation of ethanol became obstacles to the development of DEFCs. Herein, a 2D ternary cyclic Pd3Pt1Rh0.1 nanorings (NRs) catalyst with efficient EOR performance...
