КОМПОЗИТ НА ОСНОВЕ ПОРИСТОГО ТРЕХМЕРНОГО КРИОГЕЛЯ, MXENE И НАНОЧАСТИЦ СЕРЕБРА ДЛЯ УДАЛЕНИЯ МЕТИЛЕНОВОГО СИНЕГО (МС) ИЗ ВОДЫ

В этом исследовании мы сообщаем о новом композите на основе пористого трехмерного криогеля и Ti₃C₂T_x Mxene нанолистов, а также наночастиц Ag (MXene/Ag/4VP-MAAc), который был получен методом самосборки и применен для удаления метилен синего (МС) с синергизмом адсорбции и фотокаталитической деградации. Синергический эффект для полученных композитов по отношению к удалению МС связан с отличной адсорбционной способностью криогеля и фотокаталитической активностью MXene/Ag. Проведенные исследования показали, что MXene улучшают не только процесс адсорбции за счет наличия многочисленных функциональных групп, но и фотокаталитическое разложение МС благодаря своей высокой электрической проводимости. Кроме того, включение наночастиц Ag улучшает способность поглощения света, который возбуждает поверхностные электроны наночастиц Ag за счет эффекта поверхностного плазмонного резонанса. В целом, полученные результаты свидетельствуют о том, что синергетический эффект адсорбции-фотокатализа является эффективным способом удаления органического красителя из воды.
