Beschreibung
Zusammenfassung:	A method of forming copper oxide on a copper surface, the method comprising the steps a) providing a substrate comprising the copper surface, b) optionally pre-cleaning the copper surface, c) contacting the copper surface with an alkaline aqueous oxidizing solution comprising one or more than one oxidizing compound selected from the group consisting of - an aromatic sulfonic acid compound, salts thereof, - an aromatic sulfonic acid ester compound, salts thereof, - an aromatic nitro compound, and salts thereof, such that said copper oxide is formed on the copper surface. 一种在铜表面形成氧化铜的方法，所述方法包括以下步骤：a)提供包括所述铜表面的衬底，b)任选地预清洁所述铜表面，c)使所述铜表面与碱性水性氧化溶液接触以在所述铜表面上形成所述氧化铜，所述碱性水性氧化溶液包括一种或多于一种选自由以下组成的群组的氧化化合物：-芳香族磺酸化合物、其盐，-芳香族磺酸酯化合物、其盐，-芳香族硝基化合物及其盐。
