Potassium ferrite nanosheets with tin doping for enhanced large-current-density H₂ production and ultra-long life rechargeable Zn–air batteries

Abstract

Developing high-efficient trifunctional catalyst with superior electrochemical properties for stable Zn-air battery and large-current-density H2 production is of great significant. Herein, we directly introduced Sn4+ into the K2Fe4O7 (KFO) and...

NiCoP@CoNi-LDH/SSM as a multifunctional catalyst for high-efficiency water splitting and ultra-long-life rechargeable zinc-air batteries

“…Furthermore, we connected two ZABs in series and applied them as the power supply. 49 They were clearly able to light a 1.5 V LED lamp (Fig. S13a†) and could efficiently drive the two-electrode water-splitting device (NiCoP@CoNi-LDH/SSM served as both anode and cathode, Fig.…”
