“…The Raman spectra of powder samples jn-01 and jn-04 are presented in Figure 4 a,b. In the Raman spectra, peaks are seen that match up with the peaks of the corresponding ZIFs, which is in good agreement with data from the literature [ 52 , 53 , 54 , 55 , 56 , 57 , 58 ]. As seen in Figure 4 a, sample jn-01 shows the vibrational band characteristics of ZIF-8 (ZIF-L) that have been previously published in various papers [ 52 , 56 ].…”

In this study, new composite materials comprising zeolitic imidazolate framework (ZIF) structures and microchannel glass (MCG) plates were fabricated using the hydrothermal method and their morphological and spectral properties were investigated using XRD, SEM, FTIR, and Raman spectroscopy. XRD studies of powder samples revealed the presence of an additional phase for a ZIF-8 sample, whereas ZIF-67 samples, which were prepared through two different chemical routes, showed no additional phases. A detailed analysis of the FTIR and micro-Raman spectra of the composite samples revealed the formation of stable ZIF structures inside the macropores of the MCG substrate. The hydrophilic nature of the MCG substrate and its interaction with the ZIF structure resulted in the formation of stable ZIF-MCG composites. We believe that these composite materials may find a wide range of important applications in the field of sensors, molecular sieving.

“…As shown in Figure 1, both samples were having the main peaks which appeared at 2θ of 7.3°, 10.4°, 12.7°, 14.7°, 16.41°, and 18.01° and could be attributed to the (011), ( 002), ( 112), ( 022), (013), and (222). These peaks have been recognized as distinctive features of ZIF-67, consistent with findings from various studies that have investigated the synthesis of ZIF-67 [21][22][23]. The incorporation of Cu 2+ did not yield a significant change on the materials diffraction pattern, as evidenced by the similar XRD spectra of Co/Cu ZIF-67 with the single-metal ZIF-67.…”

“…Another explanation suggests that the exchange of metal ions in bimetallic MOFs provides more free charge carriers and increased interlayer distance, subsequently enhancing the conductivity [13,31]. Furthermore, Lu et al (2022) reported a significant increase in Brunauer-Emmett-Teller surface area and pore volume in Co/Cu-based MOFs, reaching 1834.71 m²/g and 0.788 cm³/g, respectively [23]. Therefore, the increase in peak current compared to single-metal ZIF-67 obtained in this study is plausible.…”

Efforts to enhance the electrochemical properties of materials have become the focus of numerous studies because these properties are essential in various fields of application. Zeolitic imidazole framework-67 (ZIF-67) is a type of metal-organic framework (MOFs) expected to demonstrate excellent performance in electrochemical applications due to its numerous distinct properties. Consequently, various strategies and techniques have been developed to improve the electrochemical performance of ZIF-67. In this study, we employed bimetallic ZIF-67 constructed with cobalt (Co) and copper (Cu) metal ions within the imidazole frameworks. The use of bimetal is expected to increase conductivity and fine-tune the physicochemical properties of ZIF-67. Using coprecipitation methods, we synthesized both single-metal and bimetallic ZIF-67 and compared their characterizations. The addition of Cu metal ions does not alter the materials phase, ensuring compatibility with the single-metal ZIF-67 structure. However, the rhombic dodecahedron morphology of ZIF-67 shifts from a smooth to a concave and rough surface in Co/Cu ZIF-67. Furthermore, Co/Cu ZIF-67 exhibits higher peak current on their cyclic voltammetry (CV) curve by 46.15 µA. The results effectively illustrate the advantages of bimetal on ZIF-67 properties and performance. Finally, this study succesfully briefly demonstrate the potential development of Co/Cu-based ZIF-67 for various electrochemical applications.

“…The Raman peaks at 477 and 684 cm −1 are typically observed with ZIF-67, whereby 477 cm −1 is attributed to the Co-N bond and the vibration mode at 684 cm −1 is assigned to the 2methylimidazolate ligand. 21 The Raman signals positioned at 198, 524 and 616 cm −1 are all assigned to F 2g and the signal at 477 cm −1 and the strongest signal at 684 cm −1 are assigned to A 1 and E g mode respectively. 22,23 FTIR spectra presented in Fig.…”
