Abstract

Thermal heterogeneous catalysis based on kinetic energy as driving force was discovered in early 1800s, and photocatalysis using potential energy as driving force was introduced in 1911. Furthermore, catalysis driven by thermal energy generated from photo energy, which is actually thermal catalysis, also has a long research history. However, only in the past decade, we developed the thermo-photo catalysis, in which the synergy of thermal and photo energies drives a catalytic process. This new type of catalysis has been explored for various processes, including (1) water splitting to hydrogen, (2) dry reforming of methane, (3) steam reforming of methane, (4) partial oxidation of methane to value-added organic compounds, and (5) hydrogenation of CO and CO2 to hydrocarbons. These findings will be discussed in this presentation with emphasis on process design and catalyst development.
