Platinum-loaded NaY zeolite (Pt/NaY) catalysts were synthesized and tested for the aqueous-phase reforming (APR) of methanol and ethanol solutions to produce hydrogen. The APR performance of the Pt/NaY catalysts was compared to the conventional γ-alumina-supported platinum (Pt/γ-Al 2 O 3 ) catalysts. The results have shown that the Pt/NaY catalysts have higher catalytic performance for the APR of methanol and ethanol than the Pt/γ-Al 2 O 3 catalysts.

Production of hydrogen (H 2 ) from biomass and organic wastes is considered an effective approach to mitigating the environmental problems caused by pollutant emissions from fossil fuel combustion and allaying our dependence on the limited oil reserves. However, current technological inefficiencies render such biomass utilization economically unviable. A promising alternative to realizing the goal of hydrogen from renewable sources is to convert biomass-derived carbohydrates to H 2 . To make the process economically attractive, catalysts with higher performance and low cost need to be developed. This research aims to develop new zeolite-based catalysts for highly efficient liquid phase conversion of carbohydrates to H 2 . Particulate platinum-loaded Y-type zeolite (Pt/NaY) catalysts have been synthesized, characterized, and evaluated for H 2 production from methanol. The catalysts were also tested for liquid phase reforming of ethanol and glucose to hydrogen. 4
