AB Phenol is one of the most important fine chemical intermediates in thesynthesis of plastics and drugs with a market size of ca. $30b1 and the commercial production is via a two-step selective oxidation of benzene, requiringhigh energy input (high temperature and high pressure) in the presence of acorrosive acidic medium, and causing serious environmental issues2–5. Here wepresent a four-phase interface strategy with well-designed Pd@Cu nanoarchitecture decorated TiO2 as a catalyst in a suspension system. The optimisedcatalyst leads to a turnover number of 16,000–100,000 for phenol generationwith respect to the active sites and an excellent selectivity of ca. 93%. Suchunprecedented results are attributed to the efficient activation of benzene bythe atomically Cu coated Pd nanoarchitecture, enhanced charge separation,and an oxidant-lean environment. The rational design of catalyst and reactionsystem provides a green pathway for the selective conversion of symmetricorganic molecules.
