Advantages

Complete conversion under MW

Complete phenol conversion achieved under 400 W low-power microwave, outperforming 95.03% under thermal catalysis at 800 °C.

Resists coking and sintering

Microwave-induced worm-like carbon nanotubes effectively suppress catalyst coking and sintering.

Works on real biomass

For real biomass MW gasification, the 7Ni-3Co@C catalyst delivered 40.92 mmol/g H2 yield.
