摘要: Abstract Green approaches to prepare high-value-added products from inexpensive raw materials is a popular research topic in chemical engineering. In the present paper, PtNPinsitu photocatalyst was prepared by in-situ photoreduction of chloroplatinic acid presence acetone. Further, sacrificial agent isopropanol could be selectively oxidized via C–C coupling into pinacol over photocatalyst, and yield reach 68.89% after raction 18 h. Radical capture isotope labeling experiments confirmed that photocatalytic selective oxidation follows OH mechanism. The results not only establish green method for synthesis but also enrich Platinum type reactions.
