Catalytic tar reforming through biochar-supported nanoparticle catalyst has become a hot topic in biomass conversion; however, the deactivation of catalysts still remain fundamental challenge. The and regeneration studies for pyrochar-based upon high temperature (700-900 oC) gathered momentum recent years, yet mechanism hydrochar-based under low (e.g., 600 oC), elusive so far. Here we report facile N2 treatment (30 mL/min 30 min) deactivated hydrochar-supported Ni facilitate activity enhance stability, by leveraging oxidization towards coke/hydrochar support hindrance, an effort to alleviate coke deposition as well suppress metal sintering without compromising its toward molecules than other atmospheres, including CO2, O2 Air. Our findings bring new understanding catalysts, enable economically industrially viable path conversion.
