With the reduction in fossil fuels, and the focus on increased greenhouse gas emissions, more sustainable and economical methods of ammonia production are needed to support the growing demand. However, to date, ammonia synthesis heavily relies on the energy-consuming and capital-intensive Haber–Bosch process. Nowadays, ammonia has become one of the most widely used industrial chemicals for economic development. Hence, the design of the hydrophobic core–shell composite catalyst provides a valuably practical strategy for ENRR as well as other water-sensitive reactions. cm −2 and great Faradaic efficiency of (31.7 ± 1.2)%, overcoming the performances of and traditional silver Our strategy affords more active sites and accessible channels for reactant species due to the porous structure of NPS cores and restrains the evolution of hydrogen by introducing the hydrophobic molecule coated on the ZIF surfaces.The composite achieves a high ammonia yield of (41.3 ± 0.9) μg Herein, we design a hydrophobic oleylamine-modified zeolitic imidazolate framework-coated nanoporous silver composite structure ( ). However, it suffers from an unsatisfactory performance due to its limited active sites and competitive hydrogen evolution reaction. Electrochemical nitrogen reduction reaction (ENRR) offers a sustainable alternative to the environmentally hazardous Haber–Bosch process for producing ammonia.
