HYBRID MATERIAL COMPRISING GRAPHENE AND IRON OXIDE, METHOD FOR MANUFACTURING THE SAME, AND APPARATUS FOR TREATING WASTE WATER USING THE SAME |
| 摘要 |
A method of manufacturing a hybrid material including graphene and iron oxide includes (a) preparing graphene oxide, (b) dispersing the graphene oxide in water to prepare a first dispersion, (c) adding divalent iron (Fe) and trivalent iron (Fe) to the first dispersion to prepare a second dispersion, (d) adjusting pH of the second dispersion to be about 8 to about 11 at about 25° C., (e) increasing the temperature of the second dispersion obtained from the (d) process up to about 80 to about 110° C., and adding a reducing agent to the second dispersion obtained from the (e) process to prepare a uniform and fine hybrid material including graphene and iron oxide. |

1. A method of manufacturing a hybrid material including graphene and iron oxide, comprising:
(a) preparing a graphene oxide; (b) dispersing the graphene oxide in water to prepare a first dispersion; (c) adding divalent iron (Fe) and trivalent iron (Fe) to the first dispersion to prepare a second dispersion; (d) adjusting pH of the second dispersion to be about 8 to about 11 at about 25° C.; (e) increasing the temperature of the second dispersion obtained from the (d) process up to about 80 to about 110° C.; and (f) adding a reducing agent to the second dispersion obtained from the (e) process to prepare a hybrid material including graphene and iron oxide. |
