text: It can be seen that both the measured current onset potential (hollow symbols) and the onset potential for H 2 O 2 generation (solid symbols) increase in the order of WO 3 < BiVO 4 < SnO 2 < TiO 2 , which agrees with the theoretical predication, supporting the validity of using \(\Delta {G_{{\rm{OH*}}}}\) as a descriptor to analyze the H 2 O 2 evolution onset (Fig. 1).
