This Review provides an overview of the emerging concepts of catalysts, membranes, and
membrane electrode assemblies (MEAs) for water electrolyzers with anion-exchange …

Electrochemical C–N coupling reactions based on abundant small molecules (such as CO2
and N2) have attracted increasing attention as a new “green synthetic strategy” for the …

The development of electrocatalysts capable of efficient reduction of nitrate (NO3−) to
ammonia (NH3) is drawing increasing interest for the sake of low carbon emission and …

Ammonia is a critical component in fertilizers, pharmaceuticals, and fine chemicals and is an
ideal, carbon-free fuel. Recently, lithium-mediated nitrogen reduction has proven to be a …

Electroreduction of nitrate to ammonia offers a promising pathway for nutrient recycling and
recovery from wastewater with energy and environmental sustainability. There have been …

Electrochemically converting nitrate ions, a widely distributed nitrogen source in industrial
wastewater and polluted groundwater, into ammonia represents a sustainable route for both …

The electrochemical conversion of nitrate pollutants into value‐added ammonia is a feasible
way to achieve artificial nitrogen cycle. However, the development of electrocatalytic nitrate …

Ammonia is of great importance in fertilizer production and chemical synthesis. It can also
potentially serve as a carbon-free energy carrier for a future hydrogen economy. Motivated …

Natural nitrogen cycle has been severely disrupted by anthropogenic activities. The overuse
of N‐containing fertilizers induces the increase of nitrate level in surface and ground waters …

In addition to its use in the fertilizer and chemical industries, ammonia is currently seen as a
potential replacement for carbon-based fuels and as a carrier for worldwide transportation of …
