	An efficient molybdenum-niobium-oxide nanomaterial was synthesized by a one-pot hydrothermal method for selective C-O (glycerol ketalization) and C-N coupling (benzylamine oxidation) reactions. The catalytically favourable properties, such as defective metal sites, truncated surfaces, and uniform metal dispersion in the MoO3-Nb2O5 nanorods, calcined at 500 degrees C (MoNb OPS-5), were confirmed by Raman, HR-TEM, and STEM-EDX, respectively. Because of improved Lewis/Bronsted acidic strength, the MoNb OPS-5 catalyst showed higher activity in glycerol ketalization and benzylamine oxidation at mild conditions, giving superior selectivity to solketal (97\%) and dibenzylimine (99\%), respectively. The MoNb OPS-5 catalyst showed high structural stability and considerable good reusability efficacy.</p>

	We developed a nanostructured catalyst consisting of WO3 nanoparticles and Nb2O5 nanorods for efficient glycerol acetalization to produce a fuel additive (solketal) at room temperature. Particularly, the WO3/Nb2O5 nanocatalyst calcined at 400 degrees C (WO3/Nb2O5-4) contains W5+ species and optimum acid sites, which enhanced glycerol conversion (92.3\%) with 95.6\% of solketal selectivity at room temperature. The structure stability of the WO3/Nb2O5-4 catalyst during the reaction is showcased by hot-filtration study and XRD/XPS characterization. However, the inadequate regeneration of the Bronsted acid sites led to a gradual decrease in the recyclable activity of the WO3/Nb2O5-4 catalyst.</p>
