Abstract In this work, uniform α-MnO2 nanorods were synthesized via a simple hydrothermal followed by ultrasonication method using ultrasonic bath (20 kHz, 100 W) without using any surfactant and template. The crystallographic phases and surface morphology were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transition electron microscopy (TEM) analysis, respectively. Functional group identification and chemical states of α-MnO2 nanorods were confirmed by Fourier-transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The as-synthesized uniform nanorods of α-MnO2 exhibit excellent catalytic conversion of toxic organic contaminant (methylene blue (MB)) in the presence of NaBH4 as reductant. The α-MnO2 exhibits excellent stability up to four repeated catalytic cycles with nearly 92% conversion. The kinetic rate constant (k), and turnover frequency (TOF) were 0.736 min−1 and 0.02 mmol mg−1 min−1, respectively. In addition, the fast electron transfer mechanism were investigated and discussed. These results open a new avenue for developing various metal oxide catalysts, which are expected to be very useful catalytic conversions. Highlights α-MnO2 nanorods were synthesized via a simple hydrothermal followed by ultrasonication method. α-MnO2 nanorods exhibit excellent catalytic conversions toward refractory pollutant, methylene blue. 99.7% was achieved for the catalytic conversion efficiency. The nanorods showed better reusability and improved catalytic cycling stability. Graphical abstract Uniform α-MnO2 nanorods were synthesized via hydrothermal followed by ultra-sonication method. They exhibited high efficient catalytic conversion of refractory pollutant, methylene blue. [DISPLAY OMISSION]
