摘要
Abstract Metal‐organic framework materials (MOFs) have the characteristics of versatile composition, high specific surface area, rich and orderly pore structure and adjustable pore size, which provide an ideal platform to develop desulfurization adsorbent and investigate the factors influencing the mercaptan removal performance. In this study, five kinds of MOFs with different adsorption sites (Cu, Ni, Zn), topological structure, pore size and defect degree were prepared and evaluated the desulfurization performance. The mercaptan adsorption capacity followed the order of CuBDC‐D>CuBDC>NiBDC>ZIF‐8>MOF‐5, and the metal site and defect were considered the main influence factors. The present study suggested that defect engineering of Cu based MOFs is a promising strategy to design efficient adsorbent for mercaptan removal.
