Graphical Abstract


Engineering the electrocatalysts’ nanoarchitectures, particularly the transition metal compounds with nanometer size, shape, facets, and composition, significantly boosts the electrocatalytic activity of the electrochemical energy reactions [1,2]. This work demonstrates a novel chemical approach for the synthesis of mesoporous nanoarchitectures (nanoflakes, nanosheets) of transition metal (nickel, cobalt, copper) hydroxides using double templates of surfactant self-assembled thin-film and foam of hydrogen bubbles concurrently produced by sodium borohydride reducing agent. The physicochemical characterizations show the nanomaterials exhibit high specific surface area and mesoporosity, various nanoarchitecture morphologies (nanoflakes and nanosheets), and compositions that can be varied in a controllable way through changes in the template compositions and deposition conditions. The electrocatalytic activity and stability of the new transition metal nanomaterials have shown significantly enhanced performance for the electrochemical energy and sensing reactions of methanol, urea, glycerol, and glucose oxidation as well as the water-splitting reactions of hydrogen and oxygen evolution. The electroactivity high-performance of the mesoporous transition metals nanoarchitectures is mainly derived from the high specific surface area and mesoporosity architecture that provide efficient charge transfer, as well as mass transport of the electroactive species.  The double templates of the surfactant-foam (DTSF) approach have the advantages of a one-pot template applicable to the synthesis wide range of nanomaterials with various compositions and nanoarchitectures at room temperature for application in electrochemical energy production and storage [1,2].
