Surface treatment is an additional process applied to the surface of a material for the purpose of adding functions such as rust and wear resistance or improving the decorative properties to enhance its appearance.Surface structure effects in electrocatalysis stand for the structure dependence of interaction between reaction molecules and electrode surface in specifying the surface atomic arrangement, chemical composition, electronic structure, and so on.

The null hypothesis is the default hypothesis. It is the hypothesis that there is no difference between the control group and the treatment group. The research hypothesis proposes that there is a significant difference between the control group and the treatment group.
