Both the "Top down approach" and the "Bottom up approach" are used for the preparation of nanomaterials.

1. Top-down approach: This method starts with a bulk material and then breaks it down into smaller pieces using mechanical, chemical, or thermal energy. This approach is often used in physical processes such as lithography or etching.

2. Bottom-up approach: This method involves building up materials from the atomic or molecular level. These methods often involve chemical reactions or self-assembly processes.

High temperature heating can be a part of these processes, but it is not a method in itself for the preparation of nanomaterials.
