Photocatalyst (IMAGE) Institute for Basic Science Caption IBS Researchers demonstrated enzyme-like heterogeneous catalysis for the first time. They developed a highly active heterogeneous TiO2 photocatalyst incorporated with many single copper atoms. They used this catalyst for the photocatalytic hydrogen production, and found that the catalyst is as active as the most active and expensive Pt-TiO2 catalyst.
