[求助] CV曲线求帮分析下!

In all the samples the different regions from 1 to 6 were named to describe different processes occurring at the surface of the catalyst,such as region (1) extending from −0.2 to 0.15 V represented the desorption process of adsorbed hydrogen (Hads) from the surface of Pt catalyst. The integrated anodic charge under hydrogen desorption area in Coulombs was denoted as QH-des. The double layer (DL)charging and discharging was shown as region (2) ranging from 0.15 to 0.45 V. An additional anodic peak observed at about +0.4 V was due to the oxidation of the surface oxide groups on the carbon. In anodic direction higher than 0.45 V one can observe 2 peaks in regions(3) and (4). The consecutive reactions, which occurred at regions(3) and (4), were due to the formation of OH and O respectively on the surface of Pt catalyst. Pt catalyzed the water dissociationand finally the Pt surface was covered with an oxide layer. Beyond region (4), the oxygen gas evolution started to dominate which resulted in a reverse scan immediately. When reversing the scan direction, the reduction of oxide layer was observed as shown in region (5). Compared to the peak of oxide formation, the peak ofoxide reduction in region (5) was shifted to lower potentials. During the cathodic scan from 0.15 V down, the underpotential deposition of hydrogen atoms occurred from the reduction of the protons. The region (6) showed the integrated cathodic charge in Coulombs of the adsorption of hydrogen was denoted as QH-ads
具体是这样的,主要是研究不同电极催化剂的性能,这里做的是纳米碳纤维负载铂金属催化剂,然后制作在GC电极上,电解质溶液为0.5M 硫酸,这是别人的文献,我有几个电化学名词不理解,还有整个反应历程也不是很明白,1)integrated anodic charge这个是什么含义,对应的 integrated cathodic charge;2)还请解释下这个反应历程,region(1-6)具体是什么含义,麻烦了!原文分析有点长,单词应该不是复杂,如果有做跟这个相关课题的那就更好了!谢谢谢谢各位了!
