Nanostructuring has emerged as one of the best tools to unlock their full potential. Tungsten oxides (WO x) are unique materials that have been rigorously studied for their chromism, photocatalysis, and sensing capabilities. 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 Tungsten oxide (WO3) nanostructures receive sustained interest for a wide variety of applications, and especially for its usage as a photocatalyst. It is therefore important to find suitable methods allowing for its easy and inexpensive large scale production. The photocatalytic activity of tungsten oxide samples was evaluated by the discoloration efficiency of methylene blue (MB) dye solutions in the dark condition and under visible light irradiation.
