My samples were drop cast on 1X1 cm2 Ni foam and dried overnight. I ran the LSV experiment in 0.5 M H2SO4 medium. I observed that there was a burning smell or thiol-like smell while running the LSV. Also, the Ni foam starts to break after the experiments. I have a batch of samples (undoped and doped), say A, A50, A100, 150, etc. having band gaps of 1.88 eV, 2.06 eV, 1.77 eV, and 1.80 eV respectively. These are obtained from Tauc plots.
