Metal–salen complexes are widely used as catalysts in numerous fundamental organic transformation reactions. Here, CoFe hydroxide/carbon nanohybrid is reported as an efficient oxygen evolution electrocatalyst derived from the in situ formed molecular Fe–salen complexes and Co 2+ ions at a low temperature of 160 °C. It has been evidenced that Fe–salen as a molecular precursor facilitates the confined‐growth of metal hydroxides, while Co 2+ plays a critical role in catalyzing the transformation of organic ligand into nanocarbons and constitutes an essential component for CoFe hydroxide. The resulting Co 1.2 Fe/C hybrid material requires an overpotential of 260 mV at a current density of 10 mA cm −2 with high durability. The high activity is contributed to uniform distribution of CoFe hydroxides on carbon layer and excellent electron conductivity caused by intimate contact between metal and nanocarbon. Given the diversity of molecular precursors, these results represent a promising approach to high‐performance carbon‐based water splitting catalysts.

laptops, rollup displays, and wearable devices. [1][2][3][4][5][6][7][8][9][10] Though, several kinds of renewable energy sources have attracted great attention including, rechargeable batteries, supercapacitors (SCs), and fuel cells. Among them, SCs hold great promise for fast charging, [11] while batteries take hours to recharge. [12] SCs have witnessed broad application prospects such as those in cameras, electric vehicles (EVs), railways, and aerospace due to their superior power density, tiny volume, and lifespan, [13,14] but small specific capacitance and low operating voltage critically fulfill the demands for EVs with high energy density. Therefore, researchers are driving toward in creating new kinds of electrode material with high specific capacity, or the operation potential window (V), and the electrochemical performance in SCs is significantly dependent on the physicochemical properties of electrode materials. [15] Nanostructured transitionmetal oxides [16][17][18][19][20] and conducting polymers are widely exploited as a positive electrode material for SCs because of their unique multiple oxidation states of transition metal ions, reversible faradic reactions, and high specific capacitance properties compared to that of carbonaceous materials (e.g., graphite, activated carbon). [21][22][23] Nevertheless, the power density, low electronic conductivity, and poor cycling stability arising from the metal oxide/polymers limit their wide application for SCs.Recently, battery-type metal selenides, phosphates, and nitrides have been attracted enormous attention, being developed as a new type of electroactive materials in the field of energy storage and conversion systems due to its low electronegativity and rich redox reactions when compared to the corresponding oxides. Indeed, some metal nitrides [24] and sulfides [25] have been reported as new electroactive materials for SCs and often show better performance than oxides. Besides, metal selenides, as an important class of metal chalcogenides, possess high electrical conductivity and widely employed as electrocatalysts, [26][27][28][29] dye-sensitized solar cells (DSSCs), [30,31] and SCs. [32] Recent reports highlight that metal selenides might be effective electrode material for SCs. [32][33][34][35][36][37][38][39][40][41][42] In their reports, the presence of selenium atom greatly enhanced electrochemical active sites. In another point of view, the cation substituted in transition metals Hybrid supercapacitors have received great interest in the field of electric vehicles and wearable electronic devices. However, developing new electrode material with high capacity and supporting substrates with good stability is still a big challenge. Herein, a facile electrodeposition technique is applied to grow Zn-Co-Se on various conductive substrates for hybrid supercapacitor. Among all, NF-supported Zn-Co-Se electrode shows a high specific capacitance of 313.45 C g −1 and good cyclical stability of 95% retention over 3000 cycles. Interestingly, the assembled hybri...
