Tóm tắt

Ô nhiễm nước do các hợp chất hữu cơ khó phân hủy như thuốc nhuộm hay kháng sinh đang đặt ra yêu cầu phát triển các vật liệu xử lý hiệu quả và bền vững. Trong bối cảnh đó, việc hệ thống hóa và đánh giá các công nghệ vật liệu mới, các thách thức, các khoảng trống nghiên cứu là cần thiết để định hướng cho các nghiên cứu ứng dụng. Bài báo này tổng quan và đánh giá toàn diện hệ vật liệu nanocomposite Ag-ZnO/chitosan trong giai đoạn 2015-2025. Các tài liệu được thu thập và sàng lọc từ các cơ sở dữ liệu khoa học quốc tế theo các tiêu chí lựa chọn xác định trước nhằm bảo đảm tính đại diện và độ tin cậy của nguồn dữ liệu. Trên cơ sở đó, nghiên cứu làm rõ cơ chế hoạt động quang xúc tác, đánh giá hiệu quả xử lý và xác định các khoảng trống nghiên cứu. Tổng quan tài liệu cho thấy vật liệu có hiệu suất phân hủy chất hữu cơ cao (70–95%), nhưng vẫn cần giải quyết các thách thức liên quan đến rửa trôi ion Ag+, độ bền cơ học của vật liệu và khả năng mở rộng quy mô để có thể tạo được hệ vật liệu an toàn, bền vững, có thể xử lý các chất hữu cơ ở quy mô công nghiệp.
