Abstract Tungsten oxide nanoparticles (WO _x NPs) are gaining increasing attention, but low stabiliity and poor dispersion of WO _x NPs hinder their catalytic applications. Herein, WO _x NPs were confined in graphene‐analogous boron nitride (g‐BN) by a one‐step, in situ method at high temperature, which can enhance the interactions between WO _x NPs and the support and control the sizes of WO _x NPs in a range of about 4–5 nm. The as‐prepared catalysts were applied in catalytic oxidation of aromatic sulfur compounds in which they showed high catalytic activity. A balance between the W loading and the size distribution of the WO _x NPs could govern the catalytic activity. Furthermore, a synergistic effect between g‐BN and WO _x NPs also contributed to high catalytic activity. The reaction mechanism is discussed in detail and the catalytic scope was enlarged.
