Abstract
We present here the size-dependent decomposition of methanol (MeOH) over narrowly distributed Pt nanoparticles supported on nanocrystalline anatase TiO2 powder. Micelle encapsulation has been used to create Pt catalysts with average particle sizes of similar to 4, 6, and 8 nm. A packed bed mass flow reactor and mass spectrometry were employed to quantify the catalyst's activity and selectivity. Among the catalysts tested the smallest nanoparticles showed the best performance including an onset reaction temperature of similar to 145 degrees C. No byproducts such as CO2 or CH4 were observed in the test range of 100-330 degrees C.
