[交流] 请教Pt-TiO2合成方法

Preparation of Pt-TiO2:
Produced by illuminating for 4 h a deoxygenated suspension of 100 mg
(white) of n-type TiO2 powder (anatase, reagent grade, MCB, particle size
125-250 μm) in 20 mL of platinizing solution (H2PtCl6 in dilute HCl, corresponding
to  100 mg of Pt) with the white light of a 2500-W xenon lamp, operating at 1600 W, followed by neutralization of the acidic solution, addition of 100 mg of hydroquinone, and 12 h reaction of 50 ℃ under nitrogen. The now grayish powder was extensively washed with distilled water and dried for 1 hat 120 ℃. The distribution of platinum on the TiOp panicle surface was found by electron microscopy to be uniform down to a resolution of <1 μm.

有人做过这个吗,如何操作?
n-type TiO2 是什么意思?
"neutralization of the acidic solution"是用什么来中和,NaOH溶液吗?
谢谢
