摘要/Abstract

摘要： 以极性氧化锌单晶(0001)面和非极性氧化锌单晶(101-0)面为研究对象，探究天然有机质(NOM)存在下不同晶面的溶解速率和腐蚀形貌的差异。实验结果表明，ZnO单晶特定晶面溶解的速率受其它晶面是否接触溶液影响，侧面接触溶液会加快顶面的溶解速率；NOM存在下(0001)面的溶解速率高于(101-0)面；不同NOM会对ZnO晶面的溶解腐蚀形貌产生不同的影响，与NOM本身性质有关。

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
