  Rational design of metal boron imidazolate cages to frameworks

  摘要：

  The targeted construction strategy for discrete metal boron-imidazolate cages to 2D frameworks is successfully realized by tetradentate boron-imidazolate acting as cage ligands and bridge linker of frameworks. This work may help us to understand the formation mechanism of extended open frameworks. Also, the cubic cages exhibited the photocatalytic behaviour of MB. (C) 2016 Elsevier B.V.

  The photocatalytic reduction of CO2 to energy-rich chemicals is highly appealing for alleviation of energy crisis and environment pollution. The introduction of different active sites is a key factor to determine the reaction activity and selectivity. Here, we demonstrate the metal ion-dependent performance for photocatalytic CO2 reduction by anchoring transition metal ions (Co2+ and Ni2+) in an amine-functionalized

  将CO 2光催化还原为富含能量的化学品对于缓解能源危机和环境污染具有很大的吸引力。不同活性位点的引入是决定反应活性和选择性的关键因素。在这里，我们通过将过渡金属离子（Co 2+和 Ni 2+）锚定在胺官能化的咪唑硼骨架 ( BIF-43 ) 中，展示了金属离子依赖的光催化 CO 2还原性能。结果，Ni@ BIF-43实现了 90.2% 的 CO 2转化为 CO 的高选择性，而 Co@ BIF-43实现了更高效的转化，CO 产率高达 2036.0 µmol g-1 h -1。重要的是，通过配位辅助策略精确控制明确结构上的孤立金属位点，使我们能够更好地了解不同金属离子物质对 CO 2光还原的具体影响以及催化机制。

  A zeolitic Cd(II)-boron-imidazolate-framework (BIF-51) with ABW topology has been successfully synthesized by using pre-synthesized B(im)(4)(-) ligands (im=imidazole) and [Cd(CH3COO)](-) building units. Ag nanoparticles (NPs) were loaded in BIF-51 by the pore confinement effect of BIFs. Sensing property of nitrobenzene on BIF-51 and catalytic property of 4-nitrophenol (4-NP) on Ag@BIF-51 were also investigated. (C) 2015 Published by Elsevier Inc.
