Crystal facet effects during the dissolution of ZnO single crystals in the presence of natural organic matter

doi:10.7523/j.ucas.2022.030

Abstract

Abstract: The polar ZnO single crystals (0001) face and non-polar ZnO single crystals (101-0) face were used to investigate the differences in dissolution rates and corrosion morphology of different crystalline facets in the presence of natural organic matter (NOM). The experimental results show that the dissolution rate of specific crystalline facets of ZnO single crystals is affected by whether the other crystalline facets are in contact with the solution, and lateral contact with the solution will accelerate the dissolution rate of the top. The dissolution rate of (0001) face is higher than that of (101-0) face in the presence of NOM. Different NOMs will have different effects on the dissolution and corrosion morphology of ZnO crystalline facets, which is related to the properties of NOM itself.

Key words: ZnO crystal, dissolution, NOM, crystal facet
