2017年12月22日 · In this study, CuNi/C nanosheet arrays on Ni foam are prepared by electrodepositing Cu on a Ni-MOF derivate. Physical measurements results indicate that Cu nanoparticles are homogeneously distributed on the Ni/C nanosheets without interference to …

2024年10月19日 · 近日，石河子大学于锋教授（点击查看介绍）团队报道了一种Cu Ni 0.75-MOF/NF（NF = nickel foam）电极材料作为N O 3 RR高效催化剂。 在-1.0 V（vs. RHE）的条件下，Cu Ni 0.75 -MOF/NF催化剂展现出优异的N O 3 RR 性能，获得了极为出色的FE（95.88%）以及氨产率（51.78 mg h -1 cm -2 ）。

2021年8月19日 · Herein, we report a facile approach to synthesize a series of MOFs [Co-MOF, Co x Ni y -MOFs (x and y represent the molar ratio of Co 2+ and Ni 2+ and x / y = 1:1, 1:5, 1:10, 1:15, and 1:20), and Ni-MOF] with a one-dimensional micro-/nanoscaled rod-like architecture.

2024年6月5日 · XRD were performed to investigate the crystal structures of Cu(OH) 2, CuNi-MOF/CF and Ru 0·004 CuNi-MOF/CF (Fig. S8). The three characteristic peaks at 2θ of 9.2°, 11.8°, and 18.6° correspond to the (100), (10-1), and (110) crystal faces of the MOF.

Herein, we propose in situ transformation strategy to architect vertically oriented bimetallic CuNi-MOF as a self-supporting electrode, leading to a decuple high specific capacitance of 1262 Cg−1 in comparison with the pristine Ni-MOF powder of 114C g−1 at 2A g−1.

2023年8月10日 · 南京航空航天大学马骏、北京大学翟茂林和巴黎萨克雷大学Mehran Mostafavi 展示了嵌入金属有机框架 (MOFs)中的原子Cu-Ni双金属位点能够在多次辐照循环中有效和选择性地产生CH3OH (~98%)。 使用具有成本效益的羟基自由基清除剂的实际电子束辐照 (200 keV；40 kGy min-1)可将CH3OH的产生率提高到0.27 mmol g-1min-1。
