Dual-functional ZnO/g-C 3 N 4 nanocomposites: effective adsorption – photocatalysis for both direct blue 71 and methylene blue removal
Ngo Trung Hoc, Nguyen Thi Hanh, Le Dinh Tuan, Nguyen Van Quang, Nguyen Tu, Quang Vinh Tran, Cao Thi Huyen Trang, Pham Thi Lan HuongZnO/g-C 3 N 4 optimally adsorbs MB at high pH and DB 71 at low pH. Its Z-scheme photocatalysis is driven by ˙OH and h + for MB degradation, whereas ˙O 2 − and e − dominate DB 71 removal.
