摘要

在CuIII-HHTP中制备了S = 0自旋基态的单原子Cu。CuIII-HHTP表现出优异的性能，尿素产率为7.780 mmol h−1 g−1，法拉第效率为23.09% at − 0.6 V (vs. RHE). Low spin state and empty (\({d}_{{{\text{x}}^{2}\text{-y}}^{2}}^{0}\)) orbitals are favorable to enhance the production urea of C–N coupling process.

Engineering Spin States of Isolated Copper Species in a Metal–Organic Framework Improves Urea Electrosynthesis

Highlights

The single-atom Cu species with S = 0 spin ground state in Cu^III-HHTP have been fabricated.
The Cu^III-HHTP exhibits remarkable performance with a high urea yield of 7.780 mmol h⁻¹ g⁻¹ with the corresponding Faradaic efficiency of 23.09% at − 0.6 V (vs. RHE).
Low spin state and empty (\({d}_{{{\text{x}}^{2}\text{-y}}^{2}}^{0}\)) orbitals are favorable to enhance the production urea of C–N coupling process.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
