The self-circulation between Ni(OH) 2 and NiOOH during water oxidation significantly lowers the overpotential of oxygen evolution reaction (OER).
The increasing demand for clean energy conversion and storage has increased interest in hydrogen production via electrolytic water splitting. However, the simultaneous of oxygen this process poses a challenge extracting pure without using ionic conducting membranes. Researchers have developed various innovative designs to overcome issue, but continuous splitting separated tanks remains desirable approach. This study presents novel, roll-to-roll that enables fully decoupled evaluation...
Production of hydrogen from water splitting has been considered as a promising solution for energy conversion and storage. Since noble metal-based structure is still the most satisfactory but scarce kind catalyst, it significant to allow practical application such catalysts by engineering heterogeneous developing green facile synthetic strategies.

A novel ultrafast heating strategy was highly effective to boost the OER activity of Iridium.
Conventional electrosynthesis of H2O2 through a two-electron oxygen reduction reaction (2e--ORR) requires continuous O2 feeding as the reactant, which is produced by evolution (OER) in water electrolysis. In principle, can be directly synthesized from once 2e--ORR coupled with OER one electrode. Unfortunately, such effective coupling has not yet been established. Herein, we created cyclic exhalation-inhalation for on-demand and on-site production facile alternating-current (AC)...
