CNFs-supported Pt catalyst for hydrogen evolution from decalin

Carbon nanofibers (CNFs) with different microstructures were synthesized as the support of Pt catalyst for decalin dehydrogenation to evolve pure hydrogen. The results show that in a liquid-film state at the temperature of 240 °C for reactor external heating, 5 wt% Pt catalyst supported on platelet CNFs gives a TOF of 732.4 mol H2/mol metal in 2 h. The microstructure of CNFs and the metal particle size have great impact on the performance of the catalyst for the reaction.
