MoS2 microspheres/MOF-derived In2S3 heterostructures with enhanced visible-light photocatalytic activity
MoS 2 microspheres/MOF-derived In 2 S 3 heterostructures were fabricated through a two-step temperature-raising hydrothermal method. MOF-derived In 2 S 3 porous structures were synthesized via a sulfidation process of MIL-68(In) precursor, and then MoS 2 microspheres further in situ grew on the surf...

heterostructures exhibited a higher photocatalytic activity towards methyl orange degradation under visible light irradiation, which should be attributed to the stronger visible light absorption as well as the effective separation of photo-generated electrons and holes.
Highlights
MIL-68(In) is used as the morphological template and the indium precursor.
One-pot synthesis involving a two-step temperature-raising hydrothermal process.
Strong visible light absorption and effective separation of photo-generated carries.
