Resumen:
The presence of transition metal ions in photocatalytic reactions is reviewed according to two main approaches: (a) the
influence of transition metal ions on the rate of photocatalytic reactions (mainly oxidation) and (b) the transformation of
the ions to less toxic species or their deposition on the semiconductor catalyst surface for recovery of expensive and useful
metals. Most of the proposed mechanisms are discussed, together with experimental physicochemical evidences that support
the involved pathways. Practical applications related to environmental protection and industrial processes are described.
