“…[ 57 ] Therefore, the VB values and CB edge potentials of BiOI, MoS 2 , and CdS could be evaluated according to the following equations. [ 57,58 ] where E vs,NHE , E vs,Ag/AgCl , E VB , and E CB refer to the standard band potential, the flat potential, the valence band edge potential, and CB edge potential, respectively. [ 42,58 ] As a result, the E VB for BiOI, MoS 2 , and CdS can be calculated to be 1.38, 1.58, and 1.3 eV, respectively.…”
