Abstract In this work, a new semicrystalline MOF synthesized from terephthalic acid and zinc nitrate is described, as well as an integral characterization of its physicochemical properties. BDC-Zn was evaluated in three applications: Methyl orange (MO) and Methyl Blue (MO) adsorption/photocatalytic degradation and H2 evolution. MO presents the best adsorption result; with a maximum adsorption capacity of 2100 mg/g, which is higher than all the MOF's reported in the literature. For H2 evolution, the activity was enhanced 24 times in photocatalyst with MO adsorbed, and 27 times for the MB adsorbed (from 47 to 1148 and 1259 μmol/gh, respectively). This result is attributed to better light adsorption and a decrease in charge recombination.

BDC-Zn MOF 通过 MO/MB 吸附敏化在太阳光下光催化析氢

摘要 在这项工作中，描述了一种由对苯二甲酸和硝酸锌合成的新型半晶 MOF，并对其理化性质进行了整体表征。BDC-Zn 在三种应用中进行了评估：甲基橙 (MO) 和甲基蓝 (MO) 吸附/光催化降解和 H2 释放。MO表现出最好的吸附效果；最大吸附容量为 2100 mg/g，高于文献中报道的所有 MOF。对于 H2 释放，吸附 MO 的光催化剂的活性提高了 24 倍，吸附 MB 的活性提高了 27 倍（分别从 47 到 1148 和 1259 μmol/gh）。这一结果归因于更好的光吸收和电荷复合的减少。
