ABSTRACT In this work, we developed a novel method to synthesize Au nanoparticles (NPs) and a TiO 2 nanocomposite catalyst with Au NPs embedded individually within the inner surface of a TiO 2 bowl‐like nanostructure (nanobowl) for the first time (denoted as Au@@TiO 2 ). This unique TiO 2 nanobowl shell can serve as a stable support for inner Au centers, and the resulting Au@@TiO2 shows markedly improved catalytic activity in the visible‐light degradation of methylene blue (MB) compared with Au‐embedded TiO 2 Hollow Spheres (HSs) and Au‐deposited commercial P25 (denoted as Au@TiO 2 and Au‐P25, respectively). Our well‐established nanobowl provides a new strategy and pathway for the synthesis of high‐performance nanocomposite catalysts.
