Ryotaro Matsuda 교수의 연구실은 다공성 금속 유기 프레임워크(MOFs) 및 배위 고체 고체(PCPs)를 중심으로, 기체 분리, 촉매 반응, 수소 이온 전도성 등 응용을 위한 구조적 유연성과 기능성 표면 기초 연구를 수행하고 있습니다. 특히, 금속 이온과 기체 분자의 상호작용을 정밀하게 제어함으로써 CO/N₂ 분리와 같은 도전적인 분리 과제를 해결하고자 하며, 산성 기능기를 도입한 고체 산 촉매 및 수소 이온 전도성 소재 개발에도 주력하고 있습니다.

Carbon monoxide (CO) produced in many large-scale industrial oxidation processes is difficult to separate from nitrogen (N2), and afterward, CO is further oxidized to carbon dioxide. Here, we report a soft nanoporous crystalline material that selectively adsorbs CO with adaptable pores, and we present crystallographic evidence that CO molecules can coordinate with copper(II) ions. The unprecedented high selectivity was achieved by the synergetic effect of the local interaction between CO and acc
A MIL-101-based porous coordination polymer (PCP) containing sulfonic acid groups is synthesized. The sulfonic groups are exposed on the pore surface and act as strong Brønsted acid sites. This solid acid PCP catalytically hydrolyzes cellulose into mono- and disaccharides and shows high durability in the catalytic reaction. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents are peer-reviewed, but not copy-edited or typeset. They are made
In situ synchrotron X-ray powder diffraction patterns of porous coordination polymers [[Cu(2)(pzdc)(2)(bpy)].G] have been measured (pzdc = pyrazine-2,3-dicarboxylate, bpy = 4,4'-bipyridine) (where G = H(2)O for CPL-2 superset H(2)()O, G = benzene for CPL-2 superset benzene, and G = void for the apohost). The structures of apohost and CPL-2 superset benzene were determined from Rietveld analysis. Adsorption of benzene in the channels induced a remarkable contraction in the crystal (b axis; 6.8%,
Transforming jungle gyms: Structural flexibility and sorption behavior can be tuned by controlling the degree of interpenetration of 3D porous coordination polymers (PCPs). The architectural connectivity of PCPs, even those that are composed of the same chemical components, has a significant impact on the structural flexibility and sorption behavior, which was confirmed by coincident XRPD/adsorption measurements.
Three new sulfonated porous coordination polymers (PCPs)/metal-organic frameworks (MOFs) have been synthesized using solvothermal methods. These PCPs possess porous structures with non-coordinating sulfonic acid groups or sulfonate with dimethyl ammonium cations and exhibit high proton conductivity at a low humidity of 60% RH (relative humidity) at ambient temperature.
