Here, we demonstrate that at ambient conditions, nickel-iron layered double hydroxide nanosheets array can achieve a promising NORR performance, delivering a maximal faradaic efficiency of 82% and a corresponding yield...

Polycrystalline SnSx (p-SnSx) nanofilm is dedicated to yielding formate with a maximal faradaic efficiency of 97% and high stability over 50 h. Moreover, when tested in a membrane electrode assembly...

Here we report that Bi-doped Co3O4 nanosheets array grown on Ni foam can selectively catalyze the HMF-to-FDCA oxidation at ambient conditions. The catalyst shows a Faradaic efficiency of 97.7%, a...

Electrochemical H2 production from water splitting is an environmentally and sustainable technique but remains a great challenge due to the sluggish anodic oxygen evolution reaction (OER). Replacing OER with the...

Exploring reversible Zn–CO2 batteries holds great promising potential for future CO2 fixation and energy supply. Herein, the bifunctional PdBi alloy anchoring on carbon substrate (BiPdC) is proposed for simultaneously catalyzing carbon dioxide reduction reaction (CO2RR) and formic acid oxidation (FAO). The synergistic effect between Pd and Bi overcomes the sluggish kinetics of CO2RR and FAO, causing the HCOOH Faraday efficiency (FEHCOOH) of 63.4% and 6.2 mA cm–2 current density for FAO. Benefiting from the CO2–HCOOH interconversion, the homemade reversible Zn–CO2 battery exhibits the optimal 52.6% FEHCOOH and 1.1 V voltage gap within 45 h of cycling.
