Understanding catalytic activity, hydrogen adsorption and methanol dissociation on TiO₂ and Pt/TiO₂ surface

Moreover, heterogeneous catalysis has also been applied to solving the problem of many aspects in our daily life, such as environmental enhancement, energy shortage, efficient synthesis. Just as its name implies, heterogeneous catalysis is catalysis where the phase of catalyst differs from the reactants or products.

Normally, it usually happens at the gas-solid or liquid-solid interface. This PhD thesis mainly addresses two types of heterogeneous reactions: the one happens at the interface between gas and solid (chapter 3, chapter 5 and chapter 6), and the other occurs between liquid and solid (chapter 4). According to the reaction properties, we tackle these two kinds of reactions with different methods.
