从图b中样品ZnO/C的Zn 2p精细谱 谱可以看出，出现了Zn0+和

From the Zn 2p fine spectrum of the sample ZnO/C in Figure b, it can be seen that the peaks of Zn0+ and Zn2+ appear. The appearance of Zn0+ is mainly due to the low pre-oxidation temperature and short oxidation time. Immediately afterwards, relative to ZnO/C, the Zn2+ peak position of the ZnO/NiMoO4 heterojunction shifts to the lower binding energy.

From the Zn 2p fine spectrum of sample ZnO / C in Figure B, it can be seen that the peaks of Zn0 + and Zn2 + appear. The appearance of Zn0 + is mainly due to the low pre oxidation temperature and short oxidation time. Then, compared with ZnO / C, the Zn2 + peak position of ZnO / NiMoO4 heterojunction moves to the low binding energy

From the fine spectrum of Zn 2p of sample ZnO/C in Figure B, it can be seen that there are peaks of Zn0+ and Zn2+, and the occurrence of Zn0+ is mainly due to the low oxidation temperature and short oxidation time in the early stage. Then, compared with ZnO/C, the Zn2+ peak position of ZnO/NiMoO4 heterojunction moves to the low binding energy.
