New types of electrocatalysts with high activity and selectivity are essential for advancing sustainable hydrogen and ammonia productions. Herein, through extensive first-principles calculations, we systematically investigated the potential of molecular nanowires (i.e., transition metal-phthalocyanine and transition metal-porphyrin nanowires), a broadly studied and experimentally synthesized class of frameworks as electrocatalysts for hydrogen and ammonia production. Our computations reveal that among the 20 candidate systems, Co-phthalocyanine/porphyrin nanowires are found to be the superior electrocatalysts for HER, while Ti-porphyrin and Mo-phthalocyanine/porphyrin nanowires exhibit excellent NRR activity with high selectivity and efficiency. Such catalytic activities primarily correlate to the electronic configurations of their d orbitals. Our study not only extends the electrocatalysis to molecular nanowire systems for the first time but also provides a design principle for accelerating the search for molecular nanowire catalysts.
