本發明之奈米粉體反應器包含一具有一微乳化區及一反應區之艙體、一分隔該微乳化區為複數個次區域之內隔板、至少一設置於該內隔板上之多孔性構件、一用以輸送一第一溶液至該次區域之一的第一進料口、一用以輸送一第二溶液至另一次區域的第二進料口以及一可輸送一第三溶液至該複數個次區域之第三進料口。該內隔板可沿一轉軸旋轉而在該反應器之徑向產生超重力，而注入之溶液則可由該反應器之中心處向外徑移動。該多孔性構件分別混合該第一溶液、該第二溶液及該第三溶液以形成一第一微乳胞及一第二微乳胞，其可在該反應區進行反應以製備該奈米粉體。The present nanoparticles reactor comprises a chamber with a micro-emulsion region and a reaction region, a plate separating the micro-emulsion region into a plurality of sub-regions, at least one porous member positioned on the plate, a first inlet for transferring a first solution to one of the sub-regions, a second inlet for transferring a second solution to another sub-region, and a third inlet for transferring a third solution to these sub-regions. The plate can rotate along a rotation shaft to generate a super gravitational force in the radial direction, and injected solution can flow from the center to the outer region of the reactor. The porous member mixes the first solution, the second solution and the third solution to form a first micell and a second micell, which will react in the reaction region to prepare the nanoparticle.
