Integrated composite electrodes for electrochemical synthesis of ammonia. This project aims to develop multifunctional composite electrodes for electrochemical synthesis of ammonia from water, nitrogen gas and renewable energy under ambient conditions. Hydrophobic subnanometre water channels will be integrated with an electrocatalyst to control supply of water as vapour, thereby effectively minimising hydrogen evolution reaction and enabling high-efficiency ammonia synthesis.

This project aims to develop multifunctional composite electrodes for electrochemical synthesis of ammonia from water, nitrogen gas and renewable energy under ambient conditions. Hydrophobic subnanometre water channels will be integrated with an electrocatalyst to control supply of water as vapour, thereby effectively minimising hydrogen evolution reaction and enabling high-efficiency ammonia synthesis. Expected outcomes include enhanced capacity in developing electrochemical reaction systems, and new fundamental knowledge of electrocatalyst design and reaction engineering. This should provide significant economic and environmental benefits by developing a sustainable manufacturing technology to transform the century-old ammonia industry.Read moreRead less
Plasma-catalytic bubbles for sustainable ammonia. Ammonia is one of the world’s most important chemicals directly sustaining over 50% of our food supply. But the current means of its production is highly eco-destructive and responsible for over 1% of global CO2 emissions, a similar value to global air travel. This project aims to produce ammonia from renewable sources of water, electricity and air, which can provide farmers with a zero-carbon fertilizer under a decentralized and even farm-level ....Plasma-catalytic bubbles for sustainable ammonia. Ammonia is one of the world’s most important chemicals directly sustaining over 50% of our food supply. But the current means of its production is highly eco-destructive and responsible for over 1% of global CO2 emissions, a similar value to global air travel. This project aims to produce ammonia from renewable sources of water, electricity and air, which can provide farmers with a zero-carbon fertilizer under a decentralized and even farm-level approach. Moreover, if driven by renewables, ammonia offers an effective means of exporting hydrogen from Australia. Hydrogen has been highlighted by the federal government as a priority technology in its Technology Investment Roadmap with ammonia seen as the best approach for its exportation. 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. Based on fuel cells, it is designed to acce ....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. 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
