Bifunctional electrodes with high electrochemical activity for oxygen evolution reaction (OER) and capacitance characteristics are essential for overall water-splitting devices and supercapacitors. Here, the S-etched Co/Mn-metal–organic frameworks (Co/Mn-MOF) derivative (MnCo2O4@Co9S8-10) electrode with dodecahedral hollow heterostructure was prepared by a vulcanization strategy, which greatly improves the bifunctional activity of the electrode.

Abstract:Brownification denotes increasing water color, partly caused by increasing dissolved organic matter of terrestrial origin in freshwater. Brownification has become a wide-spread environmental problem because water color alters the physicochemical environment and biological communities in aquatic ecosystems. However, our understanding of its ecological effects on aquatic macrophytes is limited.
