Summary:Hydrogen production from water electrolysis demands modern and improved catalytic materials with increased electrocatalytic characteristics. A simple hydrothermal approach was used to prepare lanthanum molybdate (La 4 Mo 7 O 27 ) nanoflowers. The X-ray diffraction (XRD) and scanning electron microscope (SEM) techniques were used to characterise the physical structure and crystallinity of the prepared La 4 Mo 7 O 27 nanoflowers. The SEM images reveal La 4 Mo 7 O 27 was composed of nanoflowers. The prepared La 4 Mo 7 O 27 nanoflowers were used as electrocatalyst to catalyse oxygen evolution reaction (OER) where it requires the overpotentials of 400 mV to generate hydrogen at the current density of 20 mA cm −2 , which is less than that of commercially available bare nickel foam (450 mV).
