摘要：
A process for making solid lubricants or lubricant additives or lubricant modifiers may include synthesizing two-dimensional (2D) nanoplatelets, nanorods, or nanowires of MoO3 and WO3. The process may also include creating hollow hexagonal ZnO nanotubes by refluxing a mixture of zinc nitrate and urea at a predefined temperature or a range of temperatures for a predefined period or periods of time. The process may further include growing the hollow hexagonal ZnO nanotubes around platelets, nanorods, or nanowires of the MoO3 or WO3. The process may also include creating a solid lubricant in a core-shell configuration from the hollow hexagonal ZnS nanotubes with an embedded hexagonal core of MoS2 or WS2.
