CTAB-assisted synthesis of S@rGO composite with enhanced photocatalytic activity and photostability

- S@rGO composite was prepared by a facile electrostatic attraction in the presence of CTAB.
- In the composite, rGO served as an excellent electron transporter to separate charge carriers.
- rGO also worked as a protective shell that inhibits the inner sulfur cores from being oxidized.
- S@rGO composite showed enhanced photocatalytic activity and photostability for MB degradation.
