Abstract

The invention belongs to the field of fruit fresh keeping and storage, and discloses Ag-TiO2 / Ti(NO2) / ITO photoelectrode, a photoelectric synergistic catalytic reaction apparatus based on the Ag-TiO2 / Ti(NO2) / ITO photoelectrode and application of the photoelectric synergistic catalytic reaction apparatus. A Ag-TiO2 / Ti(NO2) / ITO system is used as a photoelectrode, a TiO2 film is doped and modified byvirtue of Ag, then the plasma treatment is performed at the atmosphere pressure of N2, N is in site doped to form a novel phase, a semiconductor photocatalytic oxidation method and an electrochemicalmethod are combined to produce a synergistic effect, so that the quantum efficiency of the catalytic process can be significantly increased, when the photoelectrode synergistic catalytic reaction apparatus is applied to the fresh keeping of fruits, the effect is apparently improved compared with the single photocatalytic effect and the single electric catalytic effect, and a monopolar dynamics reaction rate constant of the C2H4 photoelectric synergistic catalytic degradation is increased from the 6.86*10<-4>(min<-1>) with no voltage to 9.06*10<-4>(min<-1>) and is increased by 32 percent.

Description

technical field

[0001] The invention belongs to the field of fresh-keeping and storage of fruits, in particular to an Ag-TiO 2 / Ti(NO 2 ) / ITO photoelectrode, photoelectric synergistic catalytic reaction device and its application. Background technique

[0002] Domestic fruit preservation and storage technology has been well developed in the past 20 years. Combined with my country's national conditions, a number of fruit preservation technologies have been developed and applied, and a relatively mature fruit preservation technology system has been formed. At present, the most effective means to ensure the quality and safety of fruits during the supply period after harvest is the fruit cold chain. At present, my country has initially established a fruit and vegetable preservation system based on storage, cold storage and controlled atmosphere storage. Mechanical refrigeration is still the most widely used fruit storage method in my country, and the number of fruits stored i...
