Fig. 1: Selective production of NH2OH from nitrate by metal phthalocyanine electrocatalysts.

The schematic diagram shows the tuning of the nitrate reduction reaction for selective NH2OH production on the molecularly dispersed electrocatalysts (MDEs) of metal phthalocyanine (MPc) supported on CNTs. The deep blue moieties represent the MPc molecules, and the black material represents the CNT substrate. The deep green, pale blue, and grey balls represent the N, O, and H atoms. The ellipse substrates represent the active sites on the electrocatalyst.
