Clean hydrogen production is highly desirable for future energy needs, making the understanding of molecular-level phenomena underlying photocatalytic hydrogen production both fundamentally and practically important. Water splitting on pure TiO₂ is inefficient, however, adding sacrificial methanol could significantly enhance the photocatalyzed H₂ production. Therefore, understanding the photochemistry of methanol on TiO₂ at the molecular level could provide important insights to its photocatalytic activity. Here, we report the first clear evidence of photocatalyzed splitting of methanol on TiO₂ derived from time-dependent two-photon photoemission (TD-2PPE) results in combination with scanning tunneling microscopy (STM). STM tip induced molecular manipulation …

During July – September 2008 pollution controls in China associated with the Beijing Olympics led to emissions reductions of up to 43%, as observed by NASA satellite instruments. Pollution from China has an impact on air quality throughout East Asia. In this poster, we examine the impact of China's pollution on Japan through the use of Aura satellite data (2005 – 2009), ozonesonde data (2000 – 2009), and data from air quality surface monitors (2000 – 2009). We also examine the year-to-year variability in meteorological flow regimes through trajectory model simulations of transport to Japan from the areas around Beijing …

On The Feasibility Of A Timely Transition To A More Sustainable Energy Future, Micha Tomkiewicz

Publications and Research

The paper uses the framework of the IPAT equation, as applied to CO2 emission, to decompose the various driving forces in the global energy use. Data from recent history are superimposed on projections of SRES IPCC scenarios to determine if enough sustainable capacity can be built to prevent irreversible ecological deterioration. The conclusion from the analysis is that, in agreement with the IPCC 4th report, until about 2030 there are no large differences between a sustainable scenario and the one that resembles “business as usual”. The sharp divergence that follows stems from different estimates in population growth and in the …
