Synthesis of two-dimensional layered double hydroxides: a systematic overview

“…sheet-on-sheet and layer-by-layer) has been considered as an effective way to enhance the performance of LDH for the target application. Although some progress has been made in this field, [129][130][131][132][133][134] we still need to pay attention to realizing the customized, low-cost and easy preparation of such materials.…”

Bimetallic electron-induced phase transformation of CoNi LDH-GO for high oxygen evolution and supercapacitor performance

“…The storage and conversion of electrochemical energy, especially capacitors and water splitting, is one of the important problems and has aroused great research interest in meeting the growing needs of environmental problems and energy crises [1][2][3]. Supercapacitors, also known as electrochemical capacitors (ECs), are a promising candidate for energy storage because of their high power, low maintenance cost, and long cycle life [4].…”

Redox-driven strong interfacial interactions between MnO2 and covalent organic nanosheets for efficient oxygen reduction electrocatalysis

“…19–23 Furthermore, these frameworks can be tuned by the incorporation of various heterocyclic aromatic rings, which can be coordinated to metal atoms, such as Mn. Thus, taking into account the high catalytic activities of redoxable MnO 2 nanosheets, 5 the excellent electrical conductivities of CONs, 19–23 and the synergistic hybridization effects of inorganic nanosheets on the resulting porosity, 24 the hybridization of a CON framework with ultrathin MnO 2 nanosheets would be expected to provide a powerful means to explore high-performance electrocatalyst materials via redox-induced interfacial bond formation. 6 However, at the time of this submission, we are unaware of any other work examining the redox-driven formation of strong interfacial interactions between reactive COFs and transition metal oxides as effective synthetic routes to highly efficient hybrid electrocatalysts.…”
