Tóm tắt
Trong nghiên cứu này, glucomannan – một popymer sinh học – được sử dụng làm chất định hướng cấu trúc trong quá trình tổng hợp các tấm nano Fe2O3 với độ xốp cao. Ảnh hưởng của nồng độ dung dịch Fe(NO3)3 đến hình thái và cấu trúc pha của Fe2O3 đã được nghiên cứu. Vật liệu được đặc trưng bằng kỹ thuật hiển vi điện tử quét, hiển vi điện tử truyền qua, hiển vi điện tử truyền qua phân giải cao, nhiễu xạ tia X, phổ tán xạ năng lượng tia X, phổ hồng ngoại biến đổi Fourier và đẳng nhiệt hấp phụ/khử hấp nitơ. Phương pháp này cho phép chế tạo các tấm nano oxit kim loại có độ xốp cao.
