A new experiment of semiconductor photoelectrochemical（PEC）property is designed. The PEC system is composed of ZnO nanorod array photoanode，Pt counter electrode，saturated calomel electrode and electrolyte. Firstly，ZnO nanorod arrays with ordered structure were grown on fluorine doped tin oxide（FTO）conductive substrate by hydrothermal method，and then Au/ZnO nanorod arrays were obtained by an appropriate amount of nano Au particles were deposited on the surface of ZnO nanorods by photodeposition method. The microstructure of the materials was analyzed by scanning electron microscope，and the properties of ZnO photoelectrode materials were tested and analyzed by UV-Vis diffuse reflection absorption spectroscopy， photoelectrochemistry and electrochemical impedance spectroscopy. It was confirmed that loading Au particles with appropriate concentration on ZnO nanorod arrays would significantly improve its photoelectric response and reduce its interfacial charge transfer resistance. The experiment can not only cultivate the rigorous scientific research attitude of undergraduates，but also develop their innovative potentials and enhance their abilities to solve complex engineering problems.

Engineering education professional certification requires students to have the ability to solve complex engineering problems, and curriculum experiment is an important part of cultivating students' ability. In this paper, taking the photocatalytic H2 production experiment as an example, the teaching reform method of material experiment course for engineering education professional certification is proposed from the aspects of experiment content design, material preparation, phenomenon observation and result analysis. In this experiment, semiconductor nanomaterial ZnIn2S4 was synthesized by onestep hydrothermal methods, and the effect of thermal treatment temperature on the aquatic H2 production rate under visible light irradiation was studied. The results show that ZnIn2S4 has the best visible light H2 production performance when the heat treatment temperature is 300 ℃, and the H2 production rate is 591.3 μmol/h. The content of this experiment is closely related to the frontier and hot spot of photocatalysis technology, which covers a lot of knowledge in classroom teaching and meets the requirement of solving complex engineering problems. It is helpful for students to consolidate basic theoretical knowledge, cultivate students'innovation and scientific research interest, and improve their scientific research literacy.

A facile hydrothermal route has been adapted to prepare the vertically ordered TiO2 nanorod arrays (NRAs), which were then characterized by X-ray diffraction (XRD) and scanning electronic microscopy (SEM). We focus our attentions towards the effect of TiCl4 pretreatments on the actual photoelectro-chemical (PEC) performance of TiO2 NRAs. The results suggested that the nanorods were ordered aligned, ~ 150 nm in diameter and 2 ~ 3 μm in length. Among them, the samples which were pretreated by 60 mmol/L TiCl4 exhibited the highest photocurrent density. The electrochemical impedance spectra (EIS) suggested that this sample displayed the smallest transfer resistance across the electrode/electrolyte interface, which might be associated with the enhanced crystal quality of TiO2 NRAs synthesized under this condition. The experiment owns a few advantages of low cost, easy operation and covering numerous knowledge. As a result, it could not only cultivate the students ’ skills of collecting, sorting and analyzing the experimental data, but also cultivate their comprehensive creativity capabilities for discovering and solving the problems.
