Fabrication of hydrophilic S/In2O3 core-shell nanocomposite for enhancement of photocatalytic performance under visible light irradiation

- The elemental core-shell heterostructure was reported for the first time.
- The hydrophilic core-shell S/In2O3 photocatalyst was prepared by ball milling.
- The rate constant of 10% S/In2O3 is 11.6 and 13.5 times that of In2O3 and S.
- The hydrophilicity and efficiently separation of carriers are major factor.
