Anti-corrosion engineering of Cu2S/FeOOH hybrid nanosheets as superior bifunctional electrocatalysts for overall water splitting

Hierarchically Self-Supporting Phosphorus-Doped CoMoO4 Nanoflowers Arrays toward Efficient Hydrogen Evolution Reaction

“…17−19 In light of this fact, nonprecious metal catalysts have been extensively investigated. A number of catalysts with excellent performance have been proposed, including phosphides, 20−22 sulfides, 23−26 oxides, 27−29 hydroxides, 30,31 carbides, 32,33 and so on, which are expected to be promising substitutes for precious metal electrocatalysts due to their low cost and simple preparation methods. 34−36 However, improving the catalytic activity of these materials remains a significant challenge due to their poor electrical conductivity.…”

Transition Metals‐Based Water Splitting Electrocatalysts on Copper‐Based Substrates: The Integral Role of Morphological Properties

“…A significant study has been designed to evaluate the catalytic and stability performance of Cu 2 S nanostructure by FeOOH hybridization. [17] The Cu 2 S was grown on a copper using a conventional solution immersion method and Na 2 S as the sulfur source. The prepared Cu 2 S nanosheets were then immersed in FeCl 2 • 6H 2 O solution for 1,2,3 and 5 hours to form Cu@Cu 2 S@FeOOH (Figure 13).…”

“…SEM images of (b) Cu@Cu 2 S nanosheets and (c) Cu@Cu 2 S@FeOOH-3H nanosheets. [17] Figure 14. SEM images of Cu@Cu 2 S@FeOOH FeOOH-3H nanosheets and Cu@Cu 2 S nanosheets after stability test.…”

“…SEM images of Cu@Cu 2 S@FeOOH FeOOH-3H nanosheets and Cu@Cu 2 S nanosheets after stability test. [17] minutes, large nanosheets were uniformly formed intersecting with the nanowire structures. Further prolonging the reaction to 45 minutes does not change the size of nanosheets which were kept forming on top of each other.…”
