Abstract Stretchable hydrogel microfibers as a novel type of ionic conductors are promising in gaining skin‐like sensing applications more diverse scenarios. However, it remains great challenge to fabricate coating‐free but water‐retaining conductive with good balance spinnability and mechanical strength.

Abstract Efficient noble‐metal free electrocatalyst for oxygen evolution reaction (OER) is critical large‐scale hydrogen production via water splitting. Inspired by Nature's cluster in photosystem II and the highly efficient artificial OER catalyst of NiFe layered double hydroxide (LDH), we designed an electrostatic 2D‐2D assembly route successfully synthesized a 2D LDH(+)‐Birnessite(−) hybrid. The as‐constructed hybrid showed advanced catalytic activity excellent stability towards under...
The Cu/Zn ratio of the CuZn electrocatalyst is known to influence selectivity CO2RR, but questions remain open about how microstructure, crystal phase, and oxidation state metal ions change interplay in composition tuning process, which need be carefully addressed for rational catalyst design.

Non-noble metal catalysts for promoting the sluggish kinetics of oxygen evolution reaction (OER) are essential to efficient water splitting sustainable hydrogen production. Birnessite has a local atomic structure similar that an oxygen-evolving complex in photosystem II, while catalytic activity birnessite is far from satisfactory.
