Abstract Developing low‐cost and highly efficient earth‐abundant oxygen evolution reaction (OER) electrocatalysts via an energy‐ time‐saving method is of great significance to the generation H 2 from electrochemical water splitting, which desirable but still challenging. Herein, a one‐step route in situ grow S‐doped FeOOH vertical nanosheets on iron foam (IF) 20 min under room temperature shown. This facile ultrafast effectively modifies surface IF into layer, full‐Fe electrode (S‐FeOOH/IF)...
Abstract Lithium–sulfur (Li–S) batteries with high theoretical energy density have been long considered as an alternative storage device to lithium‐ion batteries. Nevertheless, the polysulfide shuttle effects trigger fast capacity decay and short battery lifespan, severely hampering their practical utilizations.
