Abstract

In the reduction of metals from inorganic salts using heterogeneous photocatalysis it is necessary to add hole scavengers to provide the necessary electrons for reductive process.
In this presentation, we postulate that the reduction of metals in some organometallic compounds can occur without the addition of external sacrificial reagents because the organic matter provides the electrons. In this case, the reduction of metal occurs with the simultaneous oxidation of organic groups. Some examples are giving for mercury and arsenic organometallic compounds.
