Over oxidation
WebApr 11, 2024 · The catalytic oxidation method is thought of as having low energy consumption to effectively remove low concentration VOCs that cannot be recycled [7], [8], [9]. It requires low reaction temperatures (200-450 o C) without any additional fuel and exhibits excellent prospects in the elimination of VOCs pollution [10]. WebJan 15, 2007 · This is due to the over oxidation of the PEDOT:PSS film under UV light, which causes the cleavage of polymeric chains as well as the degradation of π-π interaction between PEDOT and PSS [42].
