Protocol to modify the surface of nano-Cu₂O using facet controlling and MOF shell coating

The morphology of nano-Cu₂O profoundly determines its catalytic performance. Here, we provide two universal and reliable techniques to modify the surface of nano-Cu₂O. First, we detail steps for the systematic tuning of the exposed facets of nano-Cu₂O ranging from low index to high index using reductant-controlled technique in the presence of sodium dodecyl sulfate. Second, we describe steps for facet-directed precipitation in which the morphology-dependent ZIF-8 (a type of zeolitic imidazolate frameworks) shells on different nano-Cu₂O are well introduced. For complete details on the use and execution of this protocol, please refer to Luo et al. (2022).
