Tính xốp của ống nano carbon kín bị nén bằng áp suất thủy lực
Tóm tắt
Dữ liệu thực nghiệm về sự hấp phụ nitơ (T = 77,3 K) từ pha khí được đo trên ống nano carbon kín thương mại được trình bày. Ngoài ra, chúng tôi cũng trình bày kết quả của sự hấp phụ N2 trên ống nano carbon được nén (sử dụng máy ép thủy lực). Để giải thích những quan sát thực nghiệm, chúng tôi thảo luận về kết quả của các mô phỏng GCMC về sự hấp phụ N2 trên các ống nano kín có thành bốn lớp hoặc bọc lại với nhau (bốn mô hình bọc lại). Chúng tôi cho thấy rằng sự thay đổi của các đồng đồ hấp phụ thực nghiệm có liên quan đến việc nén các chất hấp phụ được điều tra. Chúng giống nhau qualitatively với các quan sát lý thuyết. Dựa trên tất cả các kết quả, chúng tôi kết luận rằng trong "kiến trúc" của các ống nano, ống nano riêng lẻ giữ vai trò rất quan trọng.
