Co/MoS2 nanocomposite catalyzed H2 evolution upon dimethylamine-borane hydrolysis and in situ tandem reaction

Capturing Carbon Dioxide by Co-Decorated Molybdenum Disulfide: Boosting Efficiency Achievement of a Porous Two-Dimensional Nanomaterial via DFT Study

“…The P-MoS 2 has an appreciable capacity for Co doping with a high saturation limit. Overall, our results agree with the existing theoretical studies for similar materials, [14][15][16]28,29 indicating that here the charge transfer is from Co atoms to S atoms. Dramatic magnetism (with a magnetic moment of ∼9.42 μ B per supercell) was observed, which is attributed to the strong hybridizations between Co-3d states and 3p states of neighboring S atoms.…”

Bimetallic PtNi Nanoclusters Supported on Carbon Nanospheres as Catalysts for H2 Production from Dimethylamineborane Hydrolysis

“…In addition, the catalytic activity of the Pt 0.7 Ni 0.3 /CNS nanohybrid with other reported catalytic systems for H 2 generation from dimethylamineborane hydrolysis is also compared in Table . − As a result, the comparison had further confirmed that Pt 0.7 Ni 0.3 /CNS exhibited the highest TOF of 16,607 h –1 at 0.3 M NaOH, which exceeded the other reported catalytic systems, in H 2 generation from dimethylamineborane hydrolysis.…”

“On–Off” Control for On-Demand H2 Release upon Dimethylamineborane Hydrolysis over Ru0.8Ni0.2/MoS2 Nanohybrids

“…In the past two decades, H 2 gas is comprehensively deemed as a green, sustainable, environmental-friendly future energy source for displacing fossil fuels, − preventing further environmental deterioration, and meeting ever-increasing global energy demand. − However, the large-scale practical and industrial application of H 2 has been severely limited by its ultra-low density, liquefaction problem, and high transportation costs. − To overcome this difficulty, all kinds of hydrogen storage materials, e.g., HCOOH, − N 2 H 4 , − NaBH 4 , N 2 H 4 BH 3 , − NH 3 BH 3 , − and Me 2 NHBH 3 , have been designed and explored for the safe production, transport, and storage of hydrogen gas. Among them, dimethylamineborane (Me 2 NHBH 3 ) has recently attracted wide attention due to its cost-effectiveness (compared to NH 3 BH 3 ), excellent hydrogen storage capacity, non-flammability, non-toxicity, excellent stability, and solubility in water. − In spite of the fact that remarkable developments have been realized in the design and development of novel nanocatalysts for H 2 evolution from dimethylamineborane hydrolysis in water (eq ), − the development of “on–off” control for on-demand H 2 evolution upon dimethylamineborane hydrolysis is still a matter of supreme importance, however. − Herein, we synthesized a string of MoS 2 nanosheet-supported RuNi nanohybrids (Ru x Ni 1– x /MoS 2 ), by fixation of RuNi nanoparticles at the MoS 2 surface, for H 2 evolution upon dimethylamineborane hydrolysis at 30 °C. Particularly, the thin MoS 2 nanosheet was widely applied in photocatalytic H 2 production, antibacterial agents, microwave absorption, and water treatment due to its unique optical, physicochemical, and electrical properties. − These bimetallic Ru x Ni 1– x /MoS 2 exhibited higher ca...…”
