Summary: Molybdenum disulfide (MoS2) modified with ambient solution plasma shows improved performance in hydrogen and oxygen evolution reactions (HER and OER). The modified MoS2 exhibits low overpotential and Tafel slope, attributed to increased surface area and reduced impedance. Time-dependent plasma treatment also affects the modification, with the optimal time of 90 minutes showing better performance in HER and OER.

Summary: A highly active bi-functional electrocatalyst of Ni2P/FeP heterostructures is constructed and demonstrates the synergistic catalytic mechanism of Ni and Fe species for overall water splitting. Ni enhances the oxygen evolution reaction (OER) performance by promoting the formation of high-valence FeOOH phase, while Ni2P/Ni(OH)2 heterojunction is identified as the high active phase for hydrogen evolution reaction (HER). This study not only develops a near-commercial bifunctional electrocatalyst, but also provides insights into the catalytic mechanism of Ni and Fe.

Summary: Tungsten disulfide (WS2) is modified using ambient solution plasma for electrochemical energy applications, achieving excellent performance in hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and flexible supercapacitor applications. The optimum plasma treatment time of 60 minutes resulted in low overpotential and high Tafel slopes for HER and OER. Additionally, the flexible supercapacitor demonstrated high specific capacitance, energy density, and power density, with reliable flexibility and maintenance of capacitance and efficiency after 5000 cycles, due to increased electrochemically active surface area, lower impedance, and phase transition from 2H to 1T.

Summary: The first hydride-containing 2-electron palladium/copper alloys, PdHCu11 and PdHCu12, were synthesized. X-ray diffraction reveals that the PdHCu11 and PdHCu12 kernels consist of a central PdH unit encapsulated within a vertex-missing Cu-11 cuboctahedron and complete Cu-12 cuboctahedron, respectively. PdHCu11 shows excellent HER activity, with an onset potential of -0.05 V (at 10 mA cm(-2)) and consistent HER activity during 1000 cycles in 0.5 M H2SO4.
