Embodiment 1
[0061] The application provides degradation tests of different electrolytes to treat biomass, and the specific preparation methods are as follows:
[0062] 1. Dissolve 204.6g copper chloride dihydrate and 100mL concentrated hydrochloric acid in deionized water to prepare two 600mL mixed solutions, then add 20g bagasse and 150g titanyl sulfate to one part, and add only 20g bagasse to the other , stirred evenly, heated to 95 °C, incubated for 3 h, filtered, washed and dried at low temperature to obtain degraded liquid products and solid products, which were marked as bagasse b obtained from the degradation of single divalent copper salt, and sugarcane obtained from the synergistic degradation of copper and titanium. slag c.
[0063] 2. Dissolve 150g of titanyl sulfate and 100mL of concentrated hydrochloric acid in deionized water to prepare a 600mL mixed solution, then add 20g of bagasse, stir evenly, heat to 95°C, keep the reaction for 3h, filter, wash and dry at low temperatur...

[0066] The application provides the first biomass liquid flow fuel cell, and the specific preparation method is as follows:
[0067] 1. Preparation of anolyte: ① Dissolve 61.4g of copper chloride dihydrate and 30mL of concentrated hydrochloric acid in deionized water, then add 6g of straw and 45g of titanium oxysulfate, add water to make a mixed solution of 180mL, stir evenly and then heat At 90°C, the reaction was kept for 3 hours, and the copper-titanium synergistic degradation of straw electrolyte was obtained; in addition, ② 61.4g of copper chloride dihydrate and 30mL of concentrated hydrochloric acid were dissolved in deionized water, and then only 6g of straw was added, and water was added to make up to 180mL. The mixed solution was stirred evenly and heated to 90° C., and the reaction was kept for 3 h to obtain a separate copper salt-degrading straw electrolyte.
