Selective production of valuable chemicals from biomass by two-step conversion combining pre-oxidation and hydrothermal degradation.

Highlights: [•] We proposed two-step treatment method to overcome the problem of low selectivity. [•] Valuable chemicals were recovered selectively from biomass through proposed method. [•] The degradation mechanism of cellulose was discussed. [•] New refinery scheme of biomass was proposed. [ABSTRACT FROM AUTHOR]
