Taking the pressure off

An Author Correction to this article was published on 18 December 2018

This article has been updated

Ammonia holds promise as a clean energy carrier, but its synthesis requires high pressures and large production scales that are ill-matched to renewable, decentralized energy production. Now, researchers use metal imides to mediate ammonia production in a chemical looping process that operates under mild conditions.

    In the version of this News & Views originally published, in Fig. 1b, the compounds containing barium were labelled incorrectly. The two labels reading ‘4BaH’ should have read ‘2BaH2’, the three labels reading ‘Ba2NH’ should have read ‘BaNH’, and the label ‘BaH’ should have read ‘BaH2’. In the main text, ‘Ba2NH’ should have read ‘BaNH’, and ‘BaH’ should have read ‘BaH2’. These errors have now been corrected.
