We provide a comprehensive review of the molten salt strategy for the preparation of carbon-based materials by highlighting the roles played by molten salts. The application of these carbons in supercapacitors is also discussed.

ZnFe₂O₄ microspheres, assembled by many primary nanocrystals, have been fabricated via a facile and cost-effective solvothermal approach and applied as pseudocapacitor electrode material.

This review summarizes the synthesis methods for fabricating multishelled hollow nanostructures and provides views for such intricate hollow architectures in several emerging application areas.
