The results show that the optimum operating conditions are: at 50 ℃, pH=5, keep the concentration of cellulase to 20 μg/g medium, react time to 12 h and do not treat the apple pomace with alkali. In the range of the reacting time we adopted, the influence of the cellulose concentration can be ignored. The producing technique of the citric acid and the determine method of the citric acid also been studied by experiments.展开更多
用柠檬酸溶胶-凝胶燃烧法制备了锂离子电池正极材料L iN i0.5Co0.5O2,并对材料进行了热分析、红外分析及X射线衍射分析。研究结果表明,L iN i0.5Co0.5O2干凝胶在空气中自蔓延燃烧,燃烧产物再于800℃烧结10 h,可避免因缺氧而导致杂相L i2...用柠檬酸溶胶-凝胶燃烧法制备了锂离子电池正极材料L iN i0.5Co0.5O2,并对材料进行了热分析、红外分析及X射线衍射分析。研究结果表明,L iN i0.5Co0.5O2干凝胶在空气中自蔓延燃烧,燃烧产物再于800℃烧结10 h,可避免因缺氧而导致杂相L i2CO3、L i2N i8O10的产生,产物晶型完整。展开更多
