Study of Catalytic Hydrolysis of Alkaline NaBH4 Solution by Ru/Ni Foam Catalyst
Catalyst Chemical Hydride Hydrogen Generation Sodium Borohydride
2011/11/22
A Ni metal form was used to carry the Ru catalyst to induce the hydrogen gas from the NaBH4 solution. Results show the Ni material was replaced by Ru material. Ru has been coating twice or more to cov...
通过NaBH4还原法制备了银缓释杀菌功能载银活性炭(Ag/AC)，研究了其对大肠杆菌( E.coil)的杀灭性能和抗银流失性能.以低温液氮吸附测定活性炭的比表面积，以扫描电子显微镜(SEM)-X射线能谱仪(EDS)分析Ag/AC表面形态以及Ag的含量和分布，以X射线衍射(XRD)观察Ag/AC晶体结构.结果表明，银以单质形式负载在活性炭上.活性炭的载银量、比表面积、银颗粒的粒径及分布取决于AgNO...
通过测试线性扫描伏安曲线研究了MmNi3.2Al0.2Mn0.6Co1.0(Mm为混合稀土)经KOH处理和MnO2掺杂对催化NaBH4电氧化性能的影响. 发现NaBH4在经KOH处理后的合金上峰电流达到50 mA/cm2. 若再进行MnO2掺杂, 其电催化活性会进一步提高, 当掺杂MnO2的质量分数为10%时, MmNi3.2Al0.2Mn0.6Co1.0对NaBH4电氧化的峰电位和峰电流密度分别...

摘要 A combination of sodium borohydride and a catalytic amount of indium(III) chloride in acetonitrile reduces imines formed in-situ from aldehydes and amines to the corresponding functionalised second...
摘要 NaBH4/BiCl3复合体系在甲醇介质中对硝基化合物进行部分还原,可以获得相应的氧化偶氮苯类化合物。实验中发现此反应与反应底物的Hammett常数有着密切的关系。
9-氯-9-硼芴与NaBH4反应的理论研究
9-氯-9-硼芴 NaBH4 NaBH4 DFT 反应机理
2007/12/19
摘要 采用密度泛函理论研究了9-氯-9-硼芴与NaBH4反应的机理, 优化得到了10个中间体和12个过渡态, 并确定了可能的反应通道. 计算结果表明: 主反应通道包含了6个中间体和5个过渡态, 决速步活化能为80.35 kJ•mol－1, 9-硼芴并非反应势能面上最稳定的中间体. 解释了实验上不能成功分离出稳定中间体9-硼芴的原因.
