Artificial Photosynthesis Using All-Soild-State Photocatalysts-Photocatalytic Conversion of CO2 by H20 as an Electron Donor-

摘要

Artificial photosynthesis has recently drawn increasing amount of attention due to the fact that it allows for the direct solar-to-chemical energy conversion. However, one of the basic steps of this process, namely the reduction of CO2 by H2O to afford O2 and CO2 reduction products (CO2RPS) such as HCOOH, CO, HCHO, CH3OH, and CH4 is very difficult to achieve. In contrast to the CO2 reduction in plants and homogenous systems, the reduction of CO2 to CO2RPS over heterogeneous photocatalysts challenged by the competing reduction of H+ to H2.
