Investigation on the Adsorption and Photooxidation of Glycerol at TiO₂ Nanotubular Arrays

Table 4

Heights of the cathodic peak observed at −1 V as a function of the adsorption (𝑡_ads) and desorption (𝑡_des) times.

	KOH 0.1 M	KOH 0.1 M + glycerol 0.1 M			KOH 0.1 M
		𝑡ads = 0	𝑡ads = 4 h	𝑡ads = 20 h	𝑡des = 20 h	𝑡des = 40 h
Height of the cathodic peak (V)	−1.8	−3	−3.5	−4	−3	−2
