The electrocatalytic reduction of nitrate (NO3−) to nitrogen (N2) is an environmentally friendly approach for efficient N-cycle management (toward a nitrogen-neutral cycle). However, poor catalyst durability and the competitive hydrogen evolution reaction significantly impede its practical application. Interface-chemistry engineering, utilizing the close relationship between the catalyst surface/interface microenvironment and electron/proton transfer process, has facilitated the development of...

Trinity researchers won three of nine awards at the 2022 SFI Summit event to celebrate the best of Irish research.

Anion exchange membrane water electrolyzers (AEMWEs) feature compelling advantages over the current benchmarking proton exchange membrane water electrolyzers (PEMWEs). However, the sluggish hydrogen evolution kinetics in alkaline media and its elusive mechanism, greatly impede the practical deployment of AEMWEs. A clear understanding of alkaline hydrogen evolution reaction (HER) mechanism is a prerequisite to design advanced electrocatalysts for AEMWEs. High-performance alkaline HER electrocatal...
