Prof. Sweety Verma

Inha University, South Korea

 

I am Sweety Verma from India. I did my Ph.D. degree in chemistry from Deenbandhu Chottu Ram University of Science & Technology, India in January 2020. Topic of my thesis is-Modeling of thermodynamics properties of Oxygenated fuel additives with Hydrocarbon. During this work, I have study excess thermodynamics properties of binary & ternary mixtures & predicted these properties by using various models & theories. During that period, I have published 17 research papers in SCI & SCOPUS journals & Impact factor of these papers near 62.
I did a job as a Visiting Professor in Deenbandhu Chottu Ram University of Science & Technology, India & taught U.G & P.G students.
In Oct.2021, I am working as a Research Professor in Department of Nanoscience & Engineering, Inha University, South Korea. During this period, I have published 1 SCI paper & 2 SCI paper is communicated.

Speech title "Dense Platinum/Nickel Oxide Heterointerfaces with Abundant Oxygen Vacancies Enable Ampere-Level Current Density Ultrastable Hydrogen Evolution in Alkaline"

Abstract-Platinum (Pt) remains the benchmark electrocatalyst for alkaline hydrogen evolution reaction (HER), but its industry-scale hydrogen production is severely hampered by the lack of well-designed durable Pt-based materials that can operate at ampere-level current densities. Herein, basing on the original oxide layer and parallel convex structure on the surface of foam nickel (NF), we develop a 3D quasi-parallel architecture consisting of dense Pt nanoparticles (NPs) immobilized oxygen vacancy-rich NiOx heterojunctions (Pt/NiOx-OV) as an alkaline HER catalyst. A combined experimental and theoretical studies manifest that anchoring Pt NPs on NiOx-OV leads to electron-rich Pt species with altered density of states (DOS) distribution, which can efficiently optimize the d-band center and the adsorption of reaction intermediates as well as enhance the water dissociation ability. The as-prepared catalyst exhibits extraordinary HER performance with a low overpotential of 19.4 mV at 10 mA cm−2, a mass activity 16.3-fold higher than that of 20% Pt/C, and a long durability of more than 100 h at 1000 mA cm−2. Furthermore, the assembled alkaline electrolyzer combined with NiFe-LDH requires an extremely low voltage of 1.776 V to attain 1000 mA cm−2, and can operate stably for more than 400 h, which was rarely achieved.
