Introducing polyethyleneimine (PEI) into the electrospun fibrous membranes containing diiron mimics of [FeFe]-hydrogenase: Membrane electrodes and their electrocatalysis on proton reduction in aqueous media

Membrane electrodes assembled from electrospun fibrous membranes containing diiron mimics of [FeFe]-hydrogenae catalyse proton reduction in aqueous medium. Addition of basic polyethyleneimine (PEI) into the membranes improves the catalytic performance of the electrodes on proton reduction.217
