The invention discloses a bifunctional oxygen electrocatalyst and a preparation method and application thereof. The catalyst is A1-x-yBxCyO2, the element A is selected from one of Pt, Ir, Ru and Pd, the element B and the element C are selected from Mo, Mn, Fe, Co, Ni, Cu and Zn, and optionally, the element B is the same as the element C. The catalyst is prepared by taking chitosan, cane sugar, fructose, glucose, maltose and the like as templates, taking thiourea, ammonium chloride, urea, ammonium sulfate and the like as gas generating agents to obtain metal salt loaded three-dimensional foam, and conducting calcining. The preparation method provided by the invention has the characteristics of being simple, convenient, efficient, low in cost, environment-friendly and the like, and the obtained catalyst has very excellent electro-catalytic oxygen reduction (ORR) and oxygen evolution (OER) performance and also shows excellent performance in a zinc-air battery.

The invention provides a method for preparing ethylene glycol and 1,2-propylene glycol by using a high-concentration saccharide solution. Reaction raw materials comprise cane sugar, glucose, fructose, fructosan, xylose, soluble lower polyxylose and soluble starch. According to the method, high-concentration saccharide is used as a reaction raw material, and a high-pressure pump feeding mode is used in a reaction process which is performed in a high-pressure reaction kettle; iron, cobalt, nickel, ruthenium, rhodium, palladium, iridium and platinum which serve as transition metal in eighth, ninth and tenth groups are used as hydrogenation active ingredients; the hydrogenation active ingredients form a composite catalyst together with metal tungsten, tungsten carbide, tungsten nitride, tungsten phosphide, tungsten oxide, tungsten sulfide, tungsten chloride, tungsten hydroxide, tungsten bronze, tungstic acid, tungstate, metatungstic acid, metatungstate, paratungstic acid, paratungstate, peroxotungstic acid, peroxotungstate and tungsten-containing heteropolyacid which serve as catalytic active ingredients; and the high-concentration saccharide solution can be efficiently prepared into the ethylene glycol and the propylene glycol at high selectivity and high yield in a one-step catalytic conversion process under the hydrothermal condition that the temperature is 120 to 300 DEG C and the hydrogen pressure is 1 to 13MPa. By the method, the problem of coking of the high-concentration saccharide in the catalytic conversion process can be effectively solved, and high-concentration ethylene glycol and propylene glycol can be prepared by the high-concentration saccharide.

The invention discloses orange concentrated juice containing neotame compound sugar. The orange concentrated juice comprises orange normal juice, neotame compound sugar, fructose, citric acid, opacifier, a thickening agent, pigment, orange essence and water, wherein the neotame compound sugar further comprises at least one of saccharin sodium salt, sodium cyclamate and sucralose. The neotame compound sugar in the orange concentrated juice is high in sweetness, and pure in sweet taste, is similar to cane sugar in sweet taste, and is capable of partially or completely replacing the cane sugar in the orange juice. The orange concentrated juice is sour, sweet and palatable, pure in flavor, and full of orange flavor; more importantly, the neotame compound sugar is used for completely replacing the cane sugar as a sweetening agent, thus the cost of the orange sweetening agent is lowered. In a case where the sour of the orange juice is kept unchangeable, the consumption of acid is reduced, thus the use cost of the acid is lowered; the orange concentrated juice is free from heat so as to be drunk by special crowds which can not drink cane sugar.
