The in-situ construction of NiFe sulfide with nanoarray structure on nickel foam as efficient bifunctional electrocatalysts for overall water splitting

A facile and simple microwave-assisted synthesis method for mesoporous ultrathin iron sulfide nanosheets as an efficient bifunctional electrocatalyst for overall water splitting

“…Its satellite peak is positioned at 719.3 eV, and peaks for the Fe 3+ and Fe 2+ species of Fe 3 S 4 are found at 725.2, 712.08 eV, and 723.3, 710.28 and 706.4 eV. 49,50,[64][65][66][67] The high-resolution S 2p band confirms the major peaks at 163.5 and 162.4 eV in Fig. 2c, which match with S 2p1/2 and S 2p3/2, correspondingly.…”

Strategies to improve electrocatalytic performance of MoS2-based catalysts for hydrogen evolution reactions

“…108–111 Typically, the ceramic powder prepared by hydrothermal methods does not need high-temperature calcination treatment, which prevents grain growth, defect formation and introduction of impurities in the calcination process, so the prepared powder has high sintering activity. 112–115…”

Spherical V-doped nickel–iron LDH decorated on Ni3S2 as a high-efficiency electrocatalyst for the oxygen evolution reaction

“…31,32 Nickel sulfide (Ni 3 S 2 ) displays high catalytic activity and excellent electrical conductivity, and makes the electrical contact between the catalyst and conductive substrate closer, which is beneficial for the electrocatalytic dynamics and durability and thus can be used as a desirable conductive substrate. [33][34][35][36] Based on the above views, we coupled the defective, ultrathin V-NiFe LDH nanosheets with Ni 3 S 2 nanosheets, integrated three effective strategies into a catalyst, and designed a wonderful 3D nanosized spherical V-NiFe LDH@Ni 3 S 2 electrocatalyst. Electrochemical results show that V-NiFe LDH@Ni 3 S 2 exhibits prominent electrocatalytic properties and structural stability for the OER.…”
