Surface functionalization of MnO2 NW embellished with metal nanoparticles for self-cleaning applications
The present study investigates the synthesis of vertically aligned MnO 2 nanowires (NW) decorated with gold (Au) and silver (Ag) nanoparticles (NP) via the glancing angle deposition (GLAD) technique without a need for a catalyst. The cross-sectional field emission scanning electron microscopy (FESEM...
