本研究采用传统的间歇合成法（BS）和新型气溶胶辅助合成法（AAS）合成了HKUST-1（Cu-3（BTC）（2）; BTC 3 = 1，3，5-苯三甲酸酯），并考察了各种合成条件的影响。AAS涉及通过双流体喷嘴喷射HKUST-1前体溶液和随后的干燥，其在不到1秒的时间内连续产生球形HKUST-1纳米颗粒团聚体。AAS参数，如温度，前体浓度，和保留时间，对产品的形态，产率，选择性和孔结构特征的影响进行了讨论，使用硝酸铜作为金属前体。此外，通过BS和AAS研究了不同铜源和pH值对织构特性的影响。在低浓度和高pH值下，AAS法所得产物的BET比表面积（>1300 m2/g）高于BS法所得产物的BET比表面积（1200 m2/g）。(C)2017爱思唯尔公司All rights reserved.
In this study, HKUST-1 (Cu-3(BTC)(2); BTC3 = 1,3,5-benzenetricarboxylate) is synthesized by conventional batch synthesis (BS) and novel aerosol-assisted synthesis (AAS), and the effects of various synthesis conditions are investigated. AAS involves the spraying of an HKUST-1 precursor solution through a two fluid nozzle and subsequent drying, which continuously generates spherical HKUST-1 nanoparticle agglomerates in less than 1 s. The effects of AAS parameters, such as temperature, precursor concentration, and retention time, on the morphology, yield, selectivity, and pore textural characteristics of products are discussed using copper nitrate as a metal precursor. Furthermore, the effects of various copper sources and pH on the textural characteristics are examined by BS and AAS. At low concentration and high pH, the products obtained by AAS have a higher BET surface area (>1300 m(2)/g) than those obtained by BS (1200 m(2)/g). (C) 2017 Elsevier Inc. All rights reserved.
