摘要

为提高吸附材料对甲烷的吸附容量，采用溶剂热法合成了金属有机骨架材料HKUST-1，并进行了改性研究。HKUST-1的优化合成工艺条件为：原料摩尔比n（Cu（NO3）2·3H2O）：n（H3BTC）：n（DMF）：n（C2H5OH）：n（H2O）=1.7：1：46：60：100，晶化温度为80℃，晶化时间24 h。合成HKUST-1在25℃、3.5 MPa下的甲烷吸附容量为11.9 mmol/g。乙酸改性HKUST-1可以提高甲烷吸附容量，当反应母液中VHAc/Vsolvent=5.8%时，合成HAc-HK-1（5.8%）的甲烷吸附容量达到12.6 mmol/g。分子模拟结果表明，加入乙酸可以调控HKUST-1晶体孔道结构，增大比表面积和孔容，提高甲烷吸附容量。

Abstract

In order to improve the methane adsorption capacity of adsorbent

the metal-organic frameworks material HKUST-1 was synthesized by solvothermal method and follow by modification research. The optimized synthesis conditions were as follows:n(Cu(NO3)2·3H2O):n(H3BTC):n(DMF):n(C2H5OH):n(H2O)=1.7:1:46:60:100

the crystallization temperature of 80℃ and the crystallization time of 24 h. The methane adsorption capacity of HKUST-1 was 11.9 mmol/g at 25℃. Acid ligand modification could increase the methane adsorption capacity of HKUST-1. When VHAc/Vsolvent=5.8%

the methane adsorption capacity of HAc-HK-1(5.8%) reached 12.6 mmol/g. Molecular simulation results show that the addition of acetic acid can regulate the pore structure of HKUST-1 crystal

increase the specific surface area and pore volume

and increase the methane adsorption capacity.
