With increasing environmental concerns worldwide as well as the scarcity and
cost of metallic catalysts, the use of nanoparticles is a novel way to exploit
resources more efficiently and minimize waste. The properties of metallic
nanoclusters are highly sensitive to the size, shape, support and catalytic
conditions. This creates a complex picture but, at the same time, offers the
possibility of achieving the greatest performance of these materials, as well
as stability against deactivation. There are many opportunities in the design
of such nanocatalysts but we are just starting to understand their true
nature. In this talk we will analyze different factors influencing the
catalytic properties of Pt-based nanocatalysts. Through the understanding and
manipulating their electronic structure we will predict optimal sizes and
compositions in freestanding and MgO-supported Pt nanocatalysts. Finally, size
and composition effects will be explored in the WOx/ZrO2 acid catalyst.
