The core challenge of MnO2 as the cathode material zinc-ion batteries remains to be their poor electrochemical kinetics and stability. Herein, superfine nanowires (∼10 nm) with rich crystal defects (oxygen vacancies cavities) are demonstrated possess high efficient storage capability. Experimental theoretical studies demonstrate that facilitate adsorption diffusion hydrogen/zinc for fast ion transportation build a local electric field improved electron migration. In addition, nanostructure...

SEIRAS results show that preoxidation process can significantly improve overall reduction activity by (1)...
The poor durability of Pt-based nanoparticles dispersed on carbon black is the challenge for application long-life polymer electrolyte fuel cells. Recent work suggests that Fe- and N-codoped (Fe-N-C) might be a better support than conventional high-surface-area carbon.

Volcano plots of trends show...
The electrochemical nitrate reduction reaction (NO3RR) is a promising alternative synthetic route for sustainable ammonia (NH3) production, because it not only eliminates (NO3-) from water but also produces NH3 under mild operating conditions. However, owing to the complicated eight-electron and competition hydrogen evolution reaction, developing catalysts with high activities Faradaic efficiencies (FEs) highly imperative improve performance. In this study, Cu-doped Fe3O4 flakes are...
Abstract Lithium‐ion batteries (LIBs) based on LiNi x Co y Mn 1‐x‐y O 2 (NCM) cathode materials have been widely commercialized, because of their high energy density, favorable rate performance, and relatively low cost. However, with increased Ni content to further increase cycling stability deteriorates dramatically thus fails meet the commercial application requirements. The artificial cathode‐electrolyte‐interphase (CEI) is a promising approach solve this problem. Here, robust CEI...
