Since the 1990s, supercritical fluids for the synthesis of nanomaterials have been paid more and more attention by researchers and have gradually become one of the most important ways to prepare nanomaterials. In this study, literature data on "supercritical fluids for the synthesis of nanomaterials" from 1998 to 2020 were obtained from the Web of Science database, and the data were processed and analyzed by the bibliometric method combined with Microsoft office 2019, Origin 2018, VOSviewer, and other software, so as to obtain the research status and development trend of "supercritical fluids for the synthesis of nanomaterials". The results show that since literature on "supercritical fluids for the synthesis of nanomaterials" appeared for the first time in 1998, the number of articles published every year has risen. In terms of this field, China has become the second-largest publishing country after the United States, and China and the United States display a lot of cooperation and exchanges in this field. "Supercritical CO2", "supercritical water", "supercritical antisolvent", "surface modification", and so on have become the research hotspots of "supercritical fluids for the synthesis of nanomaterials".
