However, the Gd or B-doped TiO2 still shows low efficiency for isothiazolinone degradation, and other issues such as low stability and hydrophilicity still need to be addressed. Reducing the calcination temperature during TiO2 preparation leads to incomplete mineralization of the organic TiO2 precursor (e.g., tetrabutyl titanate).
