In the capacitance-voltage curve, hysteresis was observed, and was considered to be caused by the movement of oxygen ions and/or electrons in the YSZ film. This resulted in an unstable response at room temperature as mentioned above.
The results indicated that the mass transfer of the reagents was the dominant factor that affects the efficiency of the reaction of the photocatalytic process in the microreactor. Additionally, inverted convex cylinders were added to the microreactor, and it could enhance the mass transfer effect, improving the efficiency of CO 2 conversion.
