Beschreibungen/Notizen

• A positive‐microemulsion system (water/sodium linoleate/hexane) was used to make uniform Ag2Se nanoparticles at low temperature (7–10 °C) within five to ten minutes. The proposed interface‐reaction mechanism was corroborated by transmission electron microscopy (TEM), IR spectroscopy, and X‐ray photoelectron spectroscopy (XPS) results. This is a general method that is ideal for making other uniform nanoparticles on a large scale through simple precipitation reactions. Water/oil interface reaction: A positive‐microemulsion system was used to make uniform Ag2Se nanoparticles (see the transmission electron microscopy (TEM) image) at low temperature (7–10 °C) within 5–10 min. The proposed interface‐reaction mechanism was corroborated by TEM, IR spectroscopy, and X‐ray photoelectron spectroscopy results.
