Electrosynthesis of ammonia from nitrogen reduction reaction (NRR) at ambient conditions has been widely regarded as a green ammonia synthesis technology to replace the traditional energy- and capital-intensive Haber-Bosch process. Although single-atom electrocatalysts (SACs) may create a new catalytic paradigm, one of the key challenges hindering the rational design and development of SACs is the lack of insight into the relationship between performance and SA loading. An international team of researchers (China, Australia) demonstrated an adsorption-regulated synthetic method that uses bacterial cellulose as an adsorption regulator to control Fe3+/Co2+ impregnation on bacterial cellulose through carbothermal reduction. Fe–Co SAs was then fixed to bacterial cellulose-derived carbon via bimetallic [(O–C2)3Fe–Co(O–C2)3] coordination…read more. TECHNICAL ARTICLE
