SynthesisofMoS 2 @TiO 2 Heterostructures for photocatalytic applications Sae Bom Jeong 1 , Sung Bum ... The as-spun nanofibers were left in air for 5 h to allow the hydrolysis ofTi( O iPr )4 to go to completion ... In order to make narrow the bandgap ofTiO 2 that helps absorb all of sunlight, we demonstrate MoS 2
