摘要

The need for green energy to achieve a sustainable future is driving the development of new materials. The high surface-to-volume ratio and exposed active sites of Two-dimensional (2D) materials make them a better choice for catalysts. From the Lab scale experiment to industrial application, Overall water splitting is introduced here. VS2 as a 2D material, along with Ni and Ru as dopants, to enhance the electrical as well as the physicochemical properties. The X-ray diffraction pattern confirms the formation of Hexagonal VS2 with a high sulfur content. The field-emission scanning electron microscopy (FESEM) technique shows nanosheet-like structures. Hydrogen and oxygen evolution performance is checked using a glassy carbon electrode, as well as Overall water splitting, with the material deposited on carbon cloth. The overpotential required to reach a current density of 10 mA/cm2 is about 103.01 mV, with VS2 on the anodic side and 2% Ni- and Ru-doped VS2 on the cathodic side. This shows that both the VS2 and transition-metal-doped samples act as good catalysts in 0.5 M H2SO4 media.
