Job description
Start date: 29/09/2024 Type of opportunity Fully-funded studentship - Opportunities which are fully funded (e.g. covers all fees and stipend) Eligibility & Related Project Details Type of studentship: PhD Fee status of eligible applicants: UK and International Duration of Award if full time preferred*: 4 years 1st Supervisor: Professor Upul KG Wijayantha 2nd Supervisor: Professor Ewan McAdam / Dr Indrat Aria Intro Paragraph: A viable path toward attaining energy sustainability is the production of green hydrogen using renewable energy sources. Nonetheless, conventional water electrolysis technologies predominantly rely on freshwater, exacerbating strain on already limited resources. Seawater, as a vast and natural electrolyte source, provides an alternative but poses significant challenges, including complex ionic chemistry, insoluble by-products formation, corrosion-related issues, and chlorine evolution/oxidation reactions. The project aims to address this by pioneering the development of innovative high-performance Mo/TMNs electrocatalyst, with ultra-thin graphitic carbon coating. A minimum annual stipend of £19,237 (tax-free) plus fees for four years will be provided. Main Copy A viable path toward attaining energy sustainability is the production of green hydrogen using renewable energy sources. Nonetheless, conventional water electrolysis technologies predominantly rely on freshwater, exacerbating strain on already limited resources. Seawater, as a vast and natural electrolyte source, provides an alternative but poses significant challenges, including complex ionic chemistry, insoluble by-products formation, corrosion-related issues, and chlorine evolution/oxidation reactions. Crucially, improving energy efficiency is imperative to mitigate the overall cost of hydrogen production from seawater. Addressing these challenges involves developing high-performance electrocatalysts tailored for Seawater Electrolysis to achieve industrial-level oxygen evolution reaction (OER) current density below the potential at which competitive chlorine evolution reactions occur. Among potential candidates, transition-metal nitrides (TMNs) stand out as promising electrocatalysts due to their electron configurations, high electrical conductivities, corrosion resistance, and robust mechanical properties. Moreover, molybdenum (Mo) surfaces serve as electron pumps or reservoirs, modulating the electronic states of TMNs and enhancing catalytic activity through charge transfer. Additionally, ultra-thin graphitic carbon coatings can provide excellent conductivity and protective layers. This project offers a unique opportunity to work at the forefront of hydrogen research. As a PhD student, you will gain valuable experience in electrochemical and chemical reaction engineering. You will receive training from the UKRI-funded doctoral training centres and have the chance to participate in entrepreneurial, project management, and technique-specific training. Entry requirements Applicants should have a first or second class UK honours degree or equivalent in a related discipline. This project would suit students with knowledge and experience of chemical and reaction engineering, catalysis and materials. Funding To be eligible, applicants must be classified as home or international students. Sponsored by EPSRC Engineering Hydrogen Centre for Doctoral Training, this studentship will provide an annual stipend of £19,237 plus tuition fee. An additional travel and related expenses grant during the project worth up to £1000 per year for 4 years.
