Industrial Chemistry and Water Treatment
Improved 2-dimensional materials for hydrogen evolution reactions
H
ydrogen production from water electrolysis is one of the greenest ways to generate fuel for commercial applications.
Commercial application of water electrolysis requires low cost, high performance and stable electrocatalysts which can
operate at low overpotential. The current state-of-the-art noble metal-based electrocatalysts such as platinum are the most
efficient electrocatalysts for water electrolysis; however, their high cost and limited availability have curtailed their extensive
use as electrocatalysts. In this research, we have synthesized a catalyst using a cost-effective method for water electrolysis. The
2-dimensional catalyst was synthesized using earth abounding elements and its electrocatalytic activities were improved by one
step facile chemical treatment. Core-shell nanostructured 2-dimensional molybdenum sulfide was synthesized using chemical
vapor deposition method and was treated with hydrazine to improve its catalytic activities. Hydrazine treated catalyst showed
significant improvement in the electrocatalytic performance. They showed about 100mV improvement in overpotential after
exposure to dilute hydrazine at room temperature with a significant change in Tafel slope. Mechanism of such improvement in
the catalytic properties will be discussed in detail. Our studies suggest that simple chemical treatment process can be adopted
to improve catalytic properties of 2-dimentional material which was derived from earth abundant elements for industrial
production of hydrogen as a fuel.
