Solvothermal reaction of a partially flexible ligand, H₄L, and Cu(NO₃)₂·2.5H₂O afforded two cross-linked Kagomé lattices of formula [Cu₂(L)]_n : an acs net sustained by novel trigonal prismatic supermolecular building blocks (SBBs) and the first example of a partially pillared Kagomé net.

In recent years, low-temperature SCR (Selective Catalytic Reduction) denitrification technology has been popularized in non-power industries and has played an important role in the control of industrial flue gas NO_x emissions in China. Currently, the most commonly used catalysts in industry are V₂O₅-WO₃(MoO₃)/TiO₂, MnO₂-based catalysts, CeO₂-based catalysts, MnO₂-CeO₂ catalysts and zeolite SCR catalysts. The flue gas emitted during industrial combustion usually contains SO₂, moisture and alkali metals, which can affect the service life of SCR catalysts. This paper summarizes the mechanism of catalyst poisoning and aims to reduce the negative effect of NH₄HSO₄ on the activity of the SCR catalyst at low temperatures in industrial applications. It also presents the outstanding achievements of domestic companies in denitrification in the non-power industry in recent years. Much progress has been made in the research and application of low-temperature NH₃-SCR, and with the renewed demand for deeper NO_x treatments, new technologies with lower energy consumption and more functions need to be developed.

A flexible ligand with two 1,3-benzenedicarboxylate units has been used to construct a microporous metal–organic framework with pcu topology based on supramolecular building blocks (SBBs). The obtained Cu(II) MOF exhibits a noticeable CO₂ adsorption hysteresis and a comparable methane adsorption capacity at room temperature.

A ligand-assisted ball milling method was used to prepare the CeO₂/TiO₂ catalyst for the NH₃-SCR reaction.
