Highly efficient electrocatalytic oxygen evolution reaction on a trimetallic zeoliticimidazolateframework/nickel foam electrode

Herein, we prepared a series of monometallic (ZIF-۶۷), bimetallic (ZIF-CoCu), and novel trimetalliczeolitic imidazolate frameworks (ZIF-CoCuNi) via a facile one-step room-temperature solution precipitationmethod. The ZIF-CoCuNi exhibited an overpotential of ۳۲۵ mV and a Tafel slope of ۱۱۸ mV.dec-۱. The ECSA ofZIF-CoCuNi is ۲.۷۴ times higher than ZIF-۶۷.
