Abstract: Hydrogen as a clean, efficient, and sustainable energy has attracted considerable attention in recent years. Hydrogen production from aqueous-phase reforming (APR) of biomass-derived alcohols is preferable to other methods because of its wide renewable resource, mild reaction conditions, and low processing cost. In this paper, the progress in the APR process of different biomass-derived alcohols for H₂ production is reviewed, and the reaction mechanisms are briefly discussed for different catalysts. Pt-based catalysts exhibit high H₂ selectivity but low conversion of the alcohols. Ni-based catalysts exhibit high activity and conversion but low H₂ selectivity and yield.

Key words: Biomass, Alcohols, Hydrogen production, Aqueous-phase reforming (APR), Reaction mechanism, Catalysts
