| 发明名称 | Process for the preparation of nano zinc oxide particles | ||
| 摘要 | A process for the preparation of nano zinc oxide particles is disclosed. The process comprises of dissolving a zinc metal precursor in a solvent to obtain a first solution and dissolving a base in an alcohol to obtain an alkali solution. The alkali solution is then added to the first solution over a predetermined period of time to obtain nano zinc oxide particles in solution. | ||

| 主权项 | 1. A room temperature process for the preparation of capped nano zinc oxide particles, comprising: dissolving a zinc metal precursor in N, N dimethyl formamide to obtain a first solution; adding a capping agent to the first solution; dissolving a base in an alcohol to obtain an alkali solution; and adding a quantity of the alkali solution to the first solution over a predetermined period of time to obtain capped nano zinc oxide particles in dispersion, wherein the quantity of the alkali solution added is between 5% to 40% in excess to the quantity of the alkali solution required for a molar reaction. | ||
