The design of highly efficient, durable, and earth-abundant catalysts for the oxygen evolution reaction is crucial to a variety important energy conversion storage processes. Here, we use carbon quantum dots (CQDs, ∼5 nm) form hybrids with ultrathin nickel-iron layered double-hydroxide (NiFe-LDH) nanoplates. resulting CQD/NiFe-LDH complex exhibits high electrocatalytic activity (with an overpotential ∼235 mV in 1 M KOH at current density 10 mA cm(-2)) stability evolution, which almost exceed...
Noble metal nanomaterials have been widely used as catalysts. Common techniques for the synthesis of noble often result in crystalline nanostructures.

Transition metal (TM)-based bimetallic spinel oxides can efficiently activate peroxymonosulfate (PMS) presumably attributed to enhanced electron transfer between TMs, but the existing model cannot fully explain efficient TM redox cycling.
