Abstract

Development of highly active and robust catalysts for hydrothermal conversion of biomass-derived compounds to hydrogen is the most effective way for economically feasible hydrogen production. Precious metal catalysts have been known to be active catalysts for hydrogen production. Since precious metals are expensive these catalysts are widely used in the supported form for recycling. In the present study, following strategies were applied to increase and improve activity of supported Pt catalysts to be used in hydrothermal conditions for hydrogen production from organic-rich biomass-derived feeds: (i) integrating non-expensive metals into catalyst system, (ii) using different precursors for metals, and (iii) evaluating various carbon supportive materials with enhanced properties. The catalysts were prepared by wet impregnation method that followed by chemical reduction and thermal activation processes. The results showed that use of different precursors for Pt did not change activity of the catalysts. Co-deposition of W or Ni with Pt showed promising activity. Catalytic performance of the catalyst considerably improved by changing the type of carbons used as support for metal deposition. However, each carbon studied brought its own drawback that indicates there is a need to develop new carbons with unique properties to maximize catalytic activity of the supported metal catalysts.
