The present invention is the zinc source with the zinc acetate dihydrate, is the manganese source with acetate dihydrate manganese, adopts the hydro-thermal method process directly to prepare the zinc-oxide nano bar of manganese oxide surface modification.
Detailed technology scheme of the present invention is as follows:
A kind of preparation method of zinc-oxide nano bar of manganese oxide surface modification as shown in Figure 1, may further comprise the steps:
Step 1: with zinc acetate dihydrate ((Zn (Ac) 22H 2And acetate dihydrate manganese (Mn (Ac) O)) 22H 2O) be solute, deionized water is a solvent, and compound concentration is the zinc acetate of 0.05~1M and the mixed aqueous solution of manganese acetate, the mole that wherein adds acetate dihydrate manganese be equivalent to add 1.0~25.0% of zinc acetate dihydrate mole; Add the urea of consistent dose then to the mixed aqueous solution of zinc acetate and manganese acetate, the limit slowly adds ethanol then, and stir on the limit, dissolves fully until urea, obtains settled solution A.
Step 2: in step 1 gained settled solution A, add NaOH regulation system pH value to 12~14, obtain brown sol system B.
Step 3: brown sol system B transfers in the teflon-lined water heating kettle with step 2 gained, and hydro-thermal reaction degree 6~20 hours under 120~200 ℃ of conditions obtains brown precipitation C then.
