Copper‐based metal–organic framework decorated by CuO hair‐like nanostructures: Electrocatalyst for oxygen evolution reaction

We report a Cu‐based metal–organic framework (MOF) decorated by CuO nanostructures as an efficient catalyst for the oxygen evolution reaction (OER). MIL‐53(Cu) was synthesized by a hydrothermal approach using 1,4‐bezenedicarboxylic acid as organic precursor and further annealed at 300°C to form CuO...

Description
Summary:We report a Cu‐based metal–organic framework (MOF) decorated by CuO nanostructures as an efficient catalyst for the oxygen evolution reaction (OER). MIL‐53(Cu) was synthesized by a hydrothermal approach using 1,4‐bezenedicarboxylic acid as organic precursor and further annealed at 300°C to form CuO nanostructures on its surface. The produced electrocatalyst, CuO@MIL‐53(Cu), was characterized using various techniques. Under alkaline conditions, the developed electrocatalyst exhibited an overpotential of 801 and 336 mV versus RHE at 10 and 1 mA cm−2, respectively. The reproducibility of the catalytic performance was validated using several electrodes. It was confirmed that the CuO hair‐like nanostructures grown on MIL‐53(Cu) using thermal treatment exhibit high OER activity, good kinetics and durability. CuO@MIL‐53(Cu) is an economic noble‐metal‐free OER electrocatalyst. It has potential for application as anode material for sustainable energy technologies like batteries, fuel cells and water electrolysis. Copper‐based MOF decorated by CuO nanostructures was synthesized and characterized. The synthesized structure shows electocatalytic activity in water oxidation.
