WebNov 13, 2015 · Cats with hitherto unknown talents: Tetraalkylammonium salts are widely used for phase-transfer catalysis.It is now demonstrated that they can also function as hydrogen-bonding catalysts. The hydrogen-bonding ability of appropriately designed ammonium salt catalysts was evaluated in Mannich-type reactions of N-acyl … WebApr 11, 2024 · The generation of O–O bond and the cleavage of O–H bond usually result in a sluggish OER kinetics [34]. Therefore, higher energy (higher overpotential) over the theoretical decomposition voltage of water (1.23 V) is needed to cross the barrier, yielding O 2 gas via water electrolysis with limited practical application.
