Facile fabrication of three-dimensional mesoporous Si/SiC composites via one-step magnesiothermic reduction at relative low temperature

- The Si/SiC composites were synthesized by one-step magnesiothermic reduction.
- The mesoporous composites have a high specific surface area (655.7 m2 g−1).
- The composites exhibited a strong photoluminescence and better biocompatibility.
- The mechanisms of formation and photoluminescence of sample were discussed.
