| Popis: | The realization of encapsulating a functional guest into porous metal–organic frameworks-based thin films for optimizing and improving electrocatalysis remains a significant challenge. In this work, an Fe bis(salicylaldehyde)ethylenediimine (Salen) compound Fe(Salen) encapsulated cobalt-porphyrin framework PIZA-1 (Fe(Salen)@PIZA-1) thin film with different surface compositions was successfully developed by using a modified epitaxial layer-by-layer approach. After calcination, this composite Fe(Salen)@PIZA-1 derived thin film is first developed as oxygen evolution catalyst which attained precise control on the surface composition. The electrochemical results showed that this unique surface modified material has a good catalytic activity for OER (η = 340 mV at 10 mA cm–2) and long-term stability. This strategy gives an insight into developing a highly active, nonprecious encapsulated thin film in electrochemical energy devices. |
