Abstract：

We　synthesize　a　vertical　heterostructure　(HS)　between　tin　sulfide　(SnS)　and　molybdenum　sulfide　(MoS2)　by　chemical　vapor　deposition　based　on　the　preferential　adsorption　of　sulfur　on　MoS2.　Most　of　the　SnS　grains　nucleate　on　MoS2　nanosheets,　formatting　partially　stacked　HS　with　large　overlapping　regions.　Photoluminescence　quenching　of　MoS2　is　observed　and　illustrates　effective　charge　separation　in　HS.　The　HS　shows　increased　reverse　saturable　absorption　relative　to　MoS2　and　SnS.　The　preferential　adsorption　of　sulfur　powders　on　MoS2　and　HS　growth　reported　herein　will　provide　a　promising　approach　to　the　synthesis　of　other　two-dimensional　HS.　Copyright　©　2020　American　Chemical　Society.
