Facet-engineering and the deposition of co-catalysts lead to improvement in efficiency of semiconductors in photocatalytic applications. While facet-based charge separation is a known phenomenon and it is reported for a range of semiconductors, there is still a limited understanding of it and the mechanism behind remain elusive. Moreover, the proposed simplistic mechanism based on an offset of the valence band and conduction band of different facets is debated. Here, we show that facet-selective, photo-induced reductive or oxidative deposition of co-catalysts onto plate-like
