摘要

Designing highly active non-noble metal catalysts for hydrogenating biomass-derived platform molecules remains a significant challenge. In this study, an efficient NiCo catalyst anchored on hollow mesoporous carbon spheres (Ni1Co1/HMCs) was developed, which achieves a cyclohexanol yield of ≥ 99.0% from phenol under mild reaction conditions (150 °C under 2MPa H2 within 4 h). Comprehensive characterization techniques, including XRD, SEM, TEM, XPS characterizations confirm the formation of well-dispersed Ni-Co alloy particles, which are identified as the active centers responsible for the exceptional catalytic performance. Furthermore, the catalyst exhibits excellent recyclability, maintaining stable activity over five consecutive cycles, underscoring its potential for practical industrial applications.
