Complete ethanol oxidation reaction (EOR) in C1 pathway with 12 transferred electrons is highly desirable yet challenging in direct ethanol fuel cells. Herein, PtRh jagged nanowires synthesized via a simple wet‐chemical approach exhibit exceptional EOR mass activity of 1.63 A mgPt−1 and specific activity of 4.07 mA cm−2, 3.62‐fold and 4.28‐folds increments relative to Pt/C, respectively. High proportions...
Ni‐rich layered oxide cathode materials demonstrate high energy densities for Li‐ion batteries, but the electrochemically driven thermal runaway and mechanical degradation remain their long‐standing challenges in practical applications. Herein, it presents a novel ZrV2O7 (ZVO) coating with negative thermal expansion properties along the secondary particles and primary particle grain boundaries (GBs),...
Developing high‐efficiency and cost‐effective bifunctional catalysts for water electrolysis is fascinating but still remains challenging. Thus, diverse strategies have been utilized to boost the activity toward oxygen/hydrogen evolution reactions (OER/HER) for water splitting. Among them, composition and structure engineering as an effective strategy has received extensive attention. Here, by means...
Resin derived hard carbons (HCs) generally demonstrate remarkable electrochemical performance for both sodium ion batteries (SIBs) and potassium‐ion batteries (KIBs), but their practical applications are hindered by their high price and high temperature pyrolysis (≈1500 °C). Herein, low‐cost pitch is coated on the resin surface to compromise the cost, and meanwhile manipulate the microstructure at...
In this study, PtCu‐Mo2C heterostructure with charge redistribution is investigated via first‐principles theoretical calculations. Mo2C can promote the formation of the electron‐rich region of PtCu as an active site, displaying an optimized adsorption behavior toward hydrogen in terms of reduced thermodynamic energy barriers. Owing to the attractive density functional theory calculation results, the...
