The present work was addressed to study the visible light induced performance as photocatalysts of mesoporous NyTi1–xCexO2–y structures obtained under microwave irradiation. The titanium dioxide (TiO2) was doped with cerium and nitrogen in order to improve the quantum efficiency of the TiO2 and ...
Fe2Mo3O8/XC-72 exhibited NRR activity with an NH3 yield of 30.4 μg·h1·mg1 (0.3 V) and a Faraday efficiency of 8.2% (0.3 V). Theoretical calculations demonstrated that the electrocatalytic nitrogen fixation mechanism involved the Fe atom in the Fe2Mo3O8/XC-72 electrocatalyst acting ...
