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. %I ACS Publications
