<P>Removal of 1,3-butadiene from cigarette smoke plays an important role in human health and environmental protection. Herein, a series of UiO-66 X% containing different ratios of the -NH<SUB>2</SUB> group was synthesized via the solvothermal method by using terephthalic acid (H<SUB>2</SUB>BDC) and 2-aminoterephthalic acid (NH<SUB>2</SUB>-BDC) as ligands. Using GO as support, a series of UiO-66-NH<SUB>2</SUB>/GO Y% were prepared by controlling the ratio of UiO-66-NH<SUB>2</SUB> and GO. The effects of -NH<SUB>2</SUB> and GO contents on the structure and composition of MOFs were investigated. Finally, the different -NH<SUB>2</SUB> contents of UiO-66 X% and the different GO contents of UiO-66-NH<SUB>2</SUB>/GO Y% were applied in 1,3-butadiene removal from cigarette smoke. The results showed that UiO-66 X% with the higher contents of -NH<SUB>2</SUB> showed a higher rate of 1,3-butadiene removal, and UiO-66-NH<SUB>2</SUB>/GO Y% with the GO contents of 5% showed the highest removal rate of about 33.85%, which was 25.54% higher than that of activated carbon. In addition, the saturation capacity of the adsorbent materials for 1,3-butadiene was as high as 210.01&#x2013;239.54 mg/g, showing great potential in reducing harmful components in cigarette smoke and environmental protection.</P>
