Antibacterial Activity of Novel Complex of Gelatin Hydrolysate and Cerium黄雅钦,李承明,杨婕摘 要:A complex of gelatin hydrolysate and rare earth cerium synthesized by water-phase method was discussed in this paper. And the complex reaction between gelatin hydrolysate and rare earth cerium was verified by FT-IR. The antibacterial activity of the complex......
rate: 50 mV/s) It is noted that the improvement in catalytic activity is related to the content of Nafion in preparation solution. The current of methanol oxidation is largest for the catalyst... of 70.1% compared with the catalyst without Nafion, which is in the same order of the increase in peak current of methanol oxidation. This suggests that the improvement in catalytic activity......
Effect of Ho-doping on photocatalytic activity of nanosized TiO2 catalyst蔡河山,刘国光,吕文英,黎晓霞,余林,李大光摘 要:Ho-doped TiO2 nanoparticles with higher photocatalytic activity were prepared by an acid-catalyzed sol-gel method. The photo- catalytic decomposition of methyl orange in aqueous solution was used as a probe reaction to evaluate their photocatalytic......
