Recent advances in one-dimensional tubular composites with MoO₃-based micro/nanorods as templates

Template-mediated strategies are a versatile and scalable approach for fabricating one-dimensional (1D) tubular composites, while molybdenum trioxide (MoO₃) micro/nanorods have emerged as promising templates for engineering hollow nanostructures. In this minireview, we systematically introduce recent advancements in a series of MoO₃-based micro/nanorods for guiding the formation of 1D tubular composites with different structural characteristics. We summarize the various rational design strategies, such as hard-templating and self-templating methodologies, as well as derivative strategies with organic polymer coating and functional oxide coating for MoO₃-derived 1D tubular composites. Notably, the architectures, structures, compositions, and morphologies of these composites are discussed for their applications in catalysis, protein adsorption, and enzyme-mimic reactions, among others. Finally, we critically evaluate the prospects, challenges, and opportunities for advancing MoO₃-derived 1D tubular nanostructures toward next-generation nanocatalytic and environmental remediation technologies.
