AbstractDeveloping high-performance electrocatalysts toward hydrogen evolution reaction is important for clean and sustainable hydrogen energy, yet still challenging. Herein, we report a single-atom strategy to construct excellent metal-organic frameworks (MOFs) hydrogen evolution reaction electrocatalyst (NiRu0.13-BDC) by introducing atomically dispersed Ru. Significantly, the obtained NiRu0.13-BDC exhibits outstanding hydrogen evolution activity in all pH, especially with a low overpotential of 36 mV at a current density of 10 mA cm−2 in 1 M phosphate buffered saline solution, which is comparable to commercial Pt/C. X-ray absorption fine structures and the density functional theory calculations reveal that introducing Ru single-atom can modulate electronic structure of metal center in the MOF, leading to the optimization of binding strength for H2O and H*, and the enhancement of HER performance. This work establishes single-atom strategy as an efficient approach to modulate electronic structure of MOFs for catalyst design.

ABSTRACTWe reported the relationship between the structure of metal-organic frameworks (MOFs) and the capability of hydrogen uptake. The QSPR (quantitative structure-property relationship) method was used to find out the factor which affects the adsorption amount of hydrogen molecule on the MOFs. The derivatives which were substituted by functionalized aromatic rings showed the effect of polarization within the identical topology of the frame and similar lattice constants. And the typical series of MOFs with different topology of the frames were investigated to examine the influence of topological change. For the consideration of saturation of hydrogen adsorption amounts, the result of fitting the adsorption curve with Langmuir-Freundlich equation was used to the QSPR approach additionally. We found out that the polar surface area plays a key role on the adsorption amount of hydrogen molecule into the MOFs and the specific value of electrostatic potential surface was calculated to indicate the interaction between hydrogen molecule and MOF.
