The project will design a new solar-powered system for electrosynthesis of ammonia to replace the current energy intensive, non-sustainable process that generates 1.5% of global CO2 emissions. An innovative new system will be developed by combining cutting edge electrochemical, spectroscopic and theoretical methods. Expected key outcomes include novel concepts in the design of advanced materials, and an efficient process for the green ammonia synthesis. Given the strategic importance of ammonia as a future energy carrier for the export of Australian renewables and as a major source of fertilisers, this project should provide significant national economic and ecological benefits and is expected to have a broad reaching global impact.Read moreRead less

Electrocatalytic Generation of Ammonia from Air and Water. The aim is to directly convert nitrogen under mild conditions, using renewable power, to form ammonia for fertilisers and fuels, enabled by new, nanostructured, electrocatalysts based on single-sheet and composite materials. Unlike nitrogen fixation using a three-electrode system, the project will use a novel mixed gas- and liquid-phase electrocatalytic nitrogen reduction two-electrode reactor.

The aim is to directly convert nitrogen under mild conditions, using renewable power, to form ammonia for fertilisers and fuels, enabled by new, nanostructured, electrocatalysts based on single-sheet and composite materials. Unlike nitrogen fixation using a three-electrode system, the project will use a novel mixed gas- and liquid-phase electrocatalytic nitrogen reduction two-electrode reactor. Based on fuel cells, it is designed to accelerate the naturally sluggish nitrogen reduction reaction, NRR, significantly improving the reaction rate and selectivity. The project will also gain atomic-level understanding of the mechanism of NRR, based on in-situ spectroscopies used under operando conditions, e.g., Raman or X-ray absorption.Read moreRead less

The electrochemical manufacturing system is a sustainable alternative to traditional fertiliser manufacturing plants. The system can be assembled inexpensively and readily integrated into the renewable electricity grid, solving the greenhouse gas emission issues of the fertiliser plants. This project will identify ground-breaking electrochemical pathways for urea fertiliser and other value-added C-N containing chemicals synthesis. Gaseous CO2 and N2 will be electrochemically reacted to produce the C-N bonds. Therefore, a suite of new materials and electrochemical systems for sustainable fertiliser manufacturing will be developed. It is anticipated that the technology will revolutionise Australian fertiliser manufacturing and agriculture.Read moreRead less
