In this work we have explored a new concept of substantially increasing photocatalytic activity for H2 production of conventional<br/>semiconductors by modifying them with sub-nm Pt and Au particles. By combining both experimental and theoretical approaches, we have developed new mechanistic insights into the 17 and 36 times increase in photocatalytic activity of Pt and Au modified CdS catalysts. These nanoparticles were also explored for CO oxidation reaction utilizing applied catalysis, surface science and synchrotron techniques. Our results give a unique perspective on behavior of sub-nm metal particles and the origin of their catalytic activities.
