2018年11月1日 · ZIF-67 is a stable, hierarchical, and catalytic active substrate for supporting Ru. Ru/ZIF-67 exhibits higher catalytic activities then Ru for HG from NaBH4 hydrolysis. The optimal NaOH concentration for NaBH4 hydrolysis catalyzed by Ru/ZIF is 7.5%. Ru/ZIF can be reused for multi-cyclic HG from NaBH4 hydrolysis without regeneration.

2023年7月13日 · Here, we developed a robust metal-organic framework anchored strategy by stabilizing atomically isolated Ru oxide on UiO-67-bpydc with strong coordinating pyridine ligands.

Ru-anchored DUT-67 (Zr) MOFs with explicit defect sites have been prepared for photocatalytic nitrogen reduction. The efficient conversion of nitrogen is achieved via the introduction of Ru and unsaturated Zr sites. High transfer efficiency of carriers can be attributed to the synergistical effect of dual sites and Ru-S electronic channel.

2025年2月11日 · Specifically, Ru 0.13 /HSA 0.06 /ZIF-67 nanohybrids are prepared by in situ doping of HSA into ZIF-67 followed by an ion-exchange process. Taking advantage of the unique structures of natural enzymes and interface engineering, HSA and Ru are confined in continuous porous ZIF-67 to largely expose the active sites for the created nanopores.

In this study, ZIF-67 is particularly selected as a catalytic active support for immobilizing Ru species because ZIF-67 has proven to be highly stable in water and also hierarchically consists of Co, another catalytic active component for HG from NaBH hydrolysis.

Herein, an on-site colorimetric biosensor for cancer-related glucose and H2O2 is developed utilizing a porous ruthenium (Ru) and hemoglobin human (HSA)-doped imidazole-based metal–organic framework (Ru0.13/HSA0.06/ZIF-67) as …

2024年10月23日 · In this work, we synthesized a trimetallic heterostructure of Ru, Ni, and Co incorporated into N-doped carbon (denoted as Ru/Ni/Co@NC) by first synthesizing Ni/Co@NC from Ni-ZIF-67 polyhedrons via high-temperature carbonization, followed by Ru doping using the galvanic replacement method.

Negotiation of draft treaties between the Russian Federation and Ukraine on the legal status of the Sea of Azov and navigation in its water area as well as the legal status of the Kerch Strait.
