The periwinkle shell ash (PSA) is known to contain lanthanides and semi-conductors which are key constituents suggested for enhanced photocatalyst performance . Lanthanide elements typically have empty 5d orbitals besides the incompletely filled 4f orbitals, hence the high agility of bulk oxygen species can therefore form reactive oxygen vacancies.
