of rare earth elements from
cathode ray tubes (CRT) waste. Moreover, recycled yttrium was also
served as raw material to produce a low-cost Y-doped TiO2 nanosheets film with exposed {001} facets. An etching/dissolution
growth mechanism was postulated by systematically investigating the
influence of the reaction time. The synergistic effect of the Y dopant
and the dominant {001} facets endows TiO2 nanosheets film
with excellent activity in the photoremoval of Methyl Orange (MO)
and Cr(VI). A possible mechanism of photoremoval of MO and Cr(VI)
is proposed. This study not only contributes to recycling methods
for CRT waste but also presents a new way to prepare low-cost sustainable
photocatalytic materials using economically viable waste.
