“…It is evident that all the samples exhibit similar XRD characteristic peaks, and the ZIF-67 spectrum is in great agreement with literature reports. 44–46 The addition of FePc and FeTsPc did not alter the diffraction peaks of ZIF-67, indicating the successful coating of FePc and FeTsPc on the ZIF-67 surface. The XRD patterns show the diffraction peak of CoN (111) at 44.2° for Co–NC, FeCo–NC, and FeCo–SNC, besides the C (002) peak at 25.9° (Fig.…”

“…With the addition of [Ru(bpy) 3 ] 2+ , it was possible to obtain two phototraps with an improved selectivity of 94% for CO. Exceptionally, the hydrophobicity of In 2 O 3 @ZIF-67 can improve the product selectivity and inhibit the generation of H 2 . 185 Furthermore, doping metal on the hollow structure reduces the energy barrier of the intermediate and improves the selectivity of the product. To this end, Wang et al 186 employed ZIF-67 prepared by a hydrothermal method as a precursor to prepare single-shell ZIF-67@Co(OH) 2 HCS.…”

The conversion of CO2 into commercially available chemical fuels is a meaningful strategy for mitigating the greenhouse effect. Photocatalytic CO2 reduction is an attractive strategy due to its clean and environmentally friendly properties, and seeking efficient photocatalysts is crucial to accomplish high yield and selectivity of CO2. Metal–organic frameworks (MOFs) are favorable for photocatalytic reactions due to their high specific surface areas and abundant active sites. To facilitate the search for practical, green, and sustainable MOF photocatalysts, this paper summarizes the effects of different preparation processes on the photoresponsiveness and pore structure of MOFs, and describes the challenges of large-scale industrial production in the future. Moreover, the mechanism of MOFs photocatalytic reduction of CO2 and the factors affecting the photocatalytic performance were summarized in detail. Based on this, this review focuses on the design of band structure, construction of heterojunction, and design of goal-oriented MOF morphology to propose modification strategies and point out the key to improving photocatalytic performance. Finally, the challenges and application prospects of MOFs in photocatalytic reduction of CO2 are further discussed.

Currently, metal−organic frameworks (MOFs) have emerged as viable candidates for enduring electrode materials in nonenzyme glucose sensing. However, given the inherent water susceptibility of MOFs and their complete self-reconstruction during the process of electrochemical oxygen evolution in alkaline conditions, we are motivated to explore the truth of MOFs catalyzing glucose oxidation. In this work, we fabricated a two-dimensional cobalt-based zeolitic imidazolate framework (ZIF-L) as the electrode material for catalyzing glucose oxidation in alkaline conditions. Our explorations revealed that while the initial glucose catalytic response varied among ZIF-L samples with differing thicknesses, the ultimate steady-state catalytic performance remained largely consistent. This phenomenon arose from the transformation of ZIF-L with distinct thicknesses into CoOOH with uniform morphological and structural characteristics during the glucose catalysis process. And in situ Raman spectroscopy elucidated the sustained equilibrium within the glucose catalytic system, wherein the dynamic interconversion between CoOOH and Co(OH) 2 governs the overall process. This study contributes to an enhanced understanding of the glucose catalytic mechanism aspects of nonenzymatic glucose sensor electrode materials, offering insights that serve as inspiration for the development of advanced glucose electrode materials.
