The high cost of noble Pd/Pt required for the oxygen reduction reaction (ORR) in the cathode restricts the wide applications of fuel cells. In this study, the synthesis of a novel Pd3CuFe0.5 aerogel electrocatalyst is successfully demonstrated using self‐assembly and lyophilization techniques, employing a mild reducing agent. The resulting aerogel electrocatalyst exhibits a distinctive 3D network...
The key to increasing the rate of oxygen evolution reaction (OER) lies in accelerated four‐electron dynamics, while the key to facilitating the development of supercapacitors lies in the design of electrode materials. This paper synthesized manganese‐iron Prussian blue (MnFe‐PBA@IF) at room temperature, and hexagonal concave structures w ere prepared using a fast‐reducing matrix. Interestingly, MnFe‐PBA@IF...
Flexible electronic sensors show great potential for health monitoring but are usually limited to single sensing functionality. To enrich their functions, complicated device configurations, sophisticated material systems, and preparation processes are typically involved, obstructing their large‐scale deployment and widespread application. Herein, to achieve a good balance between simplicity and multifunctionality,...
Homogeneous and nanometric metal clusters with unique electronic structures are promising for catalysis, however, common synthesis techniques for metal clusters suffer from large size and even metal nanocrystals attributing to their high surface energy and unsaturated configurations. Herein, a generalized rapid annealing strategy for synthesizing a series of supported metal clusters as superior catalysts...
High‐energy‐density Li metal batteries (LMBs) with Nickel (Ni)‐rich cathode and Li‐metal anode have attracted extensive attention in recent years. However, commercial carbonate electrolytes bring severe challenges including poor cycling stability, severe Li dendrite growth and cathode cracks, and narrow operating temperature window, especially hardly work at below −40 °C. In this work, a 2.4 m lithium...
