摘要
Formaldehyde (HCHO) is a common indoor organic pollutant, which causes serious damage to people's health. The removal of formaldehyde is a difficult problem that human beings have to face in healthy life. MOF derivatives are a research hotspot in the field of catalysis in recent years. In this paper, a UiO-66 derived ZrO2 was selected for the study of formaldehyde degradation. Combining ZrO2 and g-C3N4 through multiple calcinations, a heterostructure was successfully constructed, which enabled the catalyst to absorb visible light. Then supported Ag by photoreduction can further improve the dispersibility and visible light absorption ability of the catalyst. When the addition amount of ZrO2 is 300 mg, [email protected]3N4/ZrO2-300 degrades 81.3 % of formaldehyde after 3 h of illumination and exhibits excellent stability. This work provides a certain reference value for the application of MOF and its derivatives in the field of formaldehyde degradation.
