AI Technical Summary

Technical Problem

Existing catalysts struggle to balance activity and selectivity in ANT hydrogenation, and the synergistic regulation mechanism of mass transfer and hydrogen transport is unclear. Traditional processes also suffer from high-pressure hazards, high costs of precious metal catalysts, and difficulties in selectivity control.

Method used

Using a Ni/MoC catalyst, an efficient hydrogen storage-hydrogenation cycle system was constructed through supercritical methanol-mediated in-situ hydrogenation of water. By utilizing metal carbides as supports and transition metals as active promoters, the surface hydrogen activation pathway was optimized to achieve directional hydrogenation of ANT.

Benefits of technology

Achieving high activity and selectivity of ANT to generate sym-OHA under mild conditions avoids the use of high-pressure hydrogen, reduces costs, improves the yield and selectivity of sym-OHA, and suppresses side reactions.
