The synthesis of highly crystalline macro-meso-microporous monolithic Cu3(btc)2 (HKUST-1; btc(3-) = benzene-1,3,5-tricarboxylate) is demonstrated by direct conversion of Cu(OH)2-based monoliths while preserving the characteristic macroporous structure. The high mechanical strength of the monoliths is promising for possible applications to continuous flow reactors.

We present mixed-valence Cu(I)Cu(II)(BTC) [henceforth Cu(I/II)-HKUST-1], post-synthetically prepared the hydroquinone (HQ) treatment of Cu(II)(BTC) (also referred to as HKUST-1) and its subsequent catalytic activity. This Cu(I/II)-HKUST-1 exhibits exceptional structural integrity and superior catalytic performance in the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction between phenylacetylene and benzyl azide. These findings highlight the potential of mixed-valence Cu-based MOFs as effective and sustainable heterogeneous catalysts for organic transformations, paving the way for future advancements in MOF-based catalysis.

Improving interfacial thermal transport is crucial for heat dissipation in devices with interfaces, such as electronics, buildings, and solar panels. Here, we design a strategy by utilizing the water adsorption-desorption process in porous metal-organic frameworks (MOFs) to tune the interfacial heat transfer, which could benefit their potential in cooling or heat dissipation applications. We observe a changeable thermal conductance across the solid/porous MOF interfaces owing to the dense water channel formed by the adsorbed water molecules in MOFs.

We prepared HKUST-1 (CuBTC; BTC = 1,3,5-benzenetricarboxylate) using a spray synthesis method with Li doping and defect created via partial replacement of HBTC with isophthalic acid (IP) to enhance the H adsorption capacity. Li-doping was performed by incorporating LiNO in HKUST-1 via spray synthesis and subsequent thermal treatment for decomposing NO, which enhances H uptake at 77 K and 1 bar per unit mass and per unit area from 2.37 wt% and 4.

Increased gas adsorption in a series of post-synthetically modified metal-organic frameworks (MOFs) of the type HKUST-1 was achieved by the partial cation exchange process. Manipulation of post-synthetic conditions demonstrates high tunability in the site substitution and gas adsorption properties during the dynamic equilibrium process. In this work, post-synthetic modification of Cu(BTC) is carried on by exposure to TM solutions (TM = Mn, Fe, Co, Ni) at different time intervals.
