Saturated Alcohols Electrocatalytic Oxidations on Ni‑Co Bimetal Oxide Featuring Balanced B‑and L‑Acidic Active Sites (IMAGE)
Caption
- NiCo–OH has a relatively high Brønsted acid sites (BASs) content (89.6%), which can promote the adsorption of OH− and inhibit the co-adsorption of OH− and alcohols, resulting in poor alcohol oxidation reaction (AOR) activity but higher oxygen evolution reaction activity.
- NiCo–OH-derived NiCo2O4 solid-acid electrocatalysts with balanced BASs (46.9%) and Lewis acid sites (53.1%) facilitates co-adsorption of alcohols molecules and OH−, thereby favoring the AOR.
- In the AOR on NiCo2O4, as the number of hydroxyl groups in C1-C6 saturated alcohols increases, the activity shows an increasing trend: C1<C2<C3<C4<C5<C6.
