Tóm tắt

CoS2 xốp giống nanocube thu được từ MOF (Co3[Fe(CN)6]2) được kết hợp với GO thông qua phương pháp tủa dung dịch và thay thế hóa học. Nhờ vào việc tải trọng thích hợp và điều chỉnh cấu trúc của CoS2, các hợp chất nano đã chuẩn bị cho thấy điện dung riêng tối đa đạt 842 F g−1 ở 0.5 A g−1, ổn định tỷ lệ cao (giữ lại dung lượng 77% từ 0.5 đến 10 A g−1), và ổn định chu kỳ dài (giữ lại dung lượng 95% qua 2000 chu kỳ).
