Zn‐Ion Hybrid Supercapacitors
In article number 2302629, Yong Hu and co‐workers propose a phosphorous‐mediated strategy to synchronically customize the enhanced zincophilicity and hydrophilicity in the carbonaceous‐based cathodes for the Zn‐ion storage. The research results reveal that the introduced P species can facilitate the adsorption capability, and improve the hydrophilicity of the as‐obtained...
Tailor‐made carbonaceous‐based cathodes with zincophilicity and hydrophilicity are highly desirable for Zn‐ion storage applications, but it remains a great challenge to achieve both advantages in the synthesis. In this work, a template electrospinning strategy is developed to synthesize nitrogen and phosphorous co‐doped hollow porous carbon nanofibers (N, P‐HPCNFs), which deliver a high capacity of...
Rational engineering electrode structure to achieve an efficient triple‐phase contact line is vital for applications such as in zinc‐air batteries and water electrolysis. Herein, a facile “MOF‐in situ‐leaching and confined‐growth‐MOF” strategy is developed to construct a breathable trifunctional electrocatalyst based on N‐doped graphitic carbon with Co nanoparticles spatially confined in an inherited...
Single‐phase perovskite oxides that contain nonprecious metals have long been pursued as candidates for catalyzing the oxygen evolution reaction, but their catalytic activity cannot meet the requirements for practical electrochemical energy conversion technologies. Here a cation deficiency‐promoted phase separation strategy to design perovskite‐based composites with significantly enhanced water oxidation...
Electrocatalysts for efficient production of ammonia from nitrogen reduction reaction (NRR) under ambient conditions are attracted growing interest in recent years, which demonstrate a great potential to replace the Haber–Bosch method which suffers the problems of the huge energy consumption and massive CO2 production. In this work, a novel electrocatalyst of Au25‐Cys‐M is fabricated for NRR under...
Gel‐polymer electrolytes are considered as a promising candidate for replacing the liquid electrolytes to address the safety concerns in Li–O2/air batteries. In this work, by taking advantage of the hydrogen bond between thermoplastic polyurethane and aerogel SiO2 in gel polymer, a highly crosslinked quasi‐solid electrolyte (FST‐GPE) with multifeatures of high ionic conductivity, high mechanical flexibility,...
Hollow nanostructures with mesoporous shells are attractive for their advantageous structure‐dependent high‐efficiency electrochemical catalytic performances. In this work, a novel nanostructure of Fe‐doped CoP hollow triangle plate arrays (Fe–CoP HTPAs) with unique mesoporous shells is designed and synthesized through a room‐temperature postsynthetic ligand exchange reaction followed by a facile...
A simple and green method is developed for the preparation of nanostructured TiO2 supported on nitrogen‐doped carbon foams (NCFs) as a free‐standing and flexible electrode for lithium‐ion batteries (LIBs), in which the TiO2 with 2.5–4 times higher loading than the conventional TiO2‐based flexible electrodes acts as the active material. In addition, the NCFs act as a flexible substrate and efficient...
On page 6724, R. Cai, Z. P. Shao, and co‐workers report a facile and green strategy to synthesize nitrogen‐doped carbon foams decorated with a nanostructured TiO2 layer under an ultra‐high loading. The mesoporous TiO2 supported on conductive carbon networks can facilitate efficient Li+ and electron transfer, delivering excellent rate and cycling performance as a flexible and free‐standing electrode...
