The chemical reduction of H[AuCl 4 ] with ortho ‐phenylenediamine in aqueous media at room temperature and ambient pressure allows the synthesis of Au nanoplates with lengths of several micrometers (see SEM image). The as‐prepared nanoplates are single crystals with a preferential growth direction along the Au (111) plane and mainly hexagonal in shape.
