H2 generation from Rh-loaded ZnS/ZnO keeps increase with recycle numbers?

01 January 1970 0 3K Report

I perform water splitting reaction under UV-visible light of ZnS/ZnO composite nanosheets with RhCl3.xH2O loading by in-situ photo-reduction. No hole scavengers used in the reaction (only water and catalysts). The H2 amount keeps increasing with recycle time. I dont know what happens here. Is there anyone has similar experiences?
