The conversion of N2 into ammonia is one of the most important processes in the chemical industry and the basis for the production of fertilizers necessary to maintain agricultural food production. The conventional Haber-Bosch process requires high energy input (1% of world energy supply) and suffers from harsh reaction conditions with an associated CO2 emission as a side product. More sustainable alternatives for ammonia synthesis are thus needed to sustain the growing demand. Electrochemical reduction of N2 (NRR) is an attractive approach that utilizes catalysts that can selectively favor one reduction product over the others at a lower reduction potentials. Despite the unprecedented efforts in utilizing metal-organic frameworks MOFs in the electrocatalytic N2 reduction, their powdery nature, high electrical resistance, poor product selectivity and low stability limits their use in catalytic applications. This presentation will describe a facile one-pot synthesis method that can modulate MOF’s conductivity via growing 2D ultrathin copper/palladium-tetrakis (4-carboxyphenyl) porphyrin Cu(PdTCPP) layers interconnected with graphene sheets giving Cu(PdTCPP)@G. This technique favors the formation of free-standing large sheets of MOF/graphene. The strong interaction between the MOF and graphene sheets allows direct electron transfer through the MOF matrix enabling them to become electrically accessible. Palladium atoms act as the main catalytic sites for NRR in a system that offers high activity and selectivity giving NH3 yield rate of 5.45 µg h-1 mg-1 MOF (52 µg h-1 mg-1 Pd ) at -0.091 V vs RHE and a Faradaic efficiency of 8.45% in 0.1 M phosphate buffer. This material showed a very promising photocurrent generation making it attractive for further development of a photocatalytic NRR that can run under sunlight, with potential to become fully sustainable.
