An in‐depth understanding of the catalyst surface evolution is crucial for precise control active sites, yet this aspect has often been overlooked. This study reveals spontaneous anion regulation mechanism Br‐doped CoP electrocatalysts in alkaline hydrogen reaction (HER) and oxygen (OER). The introduction Br modulates electronic structure Co site, endowing Br‐CoP with a more metallic character. In addition, P ion leaching promotes situ reconstruction Br‐CoOOH, which real site OER reaction....
Compounding Ni(OH) 2 and CoP to adjust the charge distribution can lead facilitation of surface reconstruction, thereby improving electrocatalytic activity. The resulting /CoP electrocatalyst exhibited excellent catalytic performance.
The electrocatalyst undergoes surface reconstruction to form the actual active component in situ during oxygen evolution reaction (OER) alkaline solution. Therefore, an in-depth understanding of process is critical establishing a well-defined structure-component-property relationship pursuit efficient electrocatalysts. In Raman and ex structure analysis were used capture F-Fe-CoP OER process. shows that leaching F accelerates dynamic response CoP remodeling rapidly transform into...
There is still a major bottleneck in improving photoelectrochemical (PEC) water oxidation reaction efficiency which the high recombination of photo-generated carriers. The design and development pathway for transfer holes an efficient strategy to suppress photogenerated electron-hole pairs. established by Al2O3 passivation layer zeolitic imidazolate framework-8 (ZIF-8) co-catalyst facilitate separation pairs, thereby promoting WO3 photoanode reaction. results demonstrate superior performance...
Because of the excellent conductivity, tunability elements and surface groups, MXenes are seen as promising electrode materials for lithium-ion storage devices. However, Van der Waals force causes MXene nanosheets to aggregate re-stack, limiting their applications. Here, we design a carbon-coated nanofiber (C@MXene) free-standing with 3D conductive network flexibility overcome intrinsic stacking agglomeration in MXene. Furthermore, provides fast lanes electron transfer, improves...
