Abstract

Here, we present a correlative microscopic analysis of electrodeposited films from catechol solutions in aqueous electrolytes. The films were prepared in a miniaturized electrochemical cell and were analyzed by identical location transmission electron microscopy, scanning transmission X-ray microscopy, and atomic force microscopy. Thanks to this combined approach, we have shown that the electrodeposited films are constituted of ultrathin graphite oxide nanosheets. Detailed information about the electronic structure of the films was obtained by X-ray absorption near edge structure spectroscopy. These results show the large potential of soft electrochemical conditions for the bottom-up production of ultrathin graphite oxide nanosheet films via a one-pot green chemistry approach from simple organic building blocks.
