Paloma Mingueza-Verdejo et al.
The synthesis of alkyl halides can be performed by simply halide exchange reactions between two different alkyl halides, catalyzed by aluminosilicates. Here, we show that commercially available alumina shows a superior catalytic activity fo...
Catalyst Protonation Changes the Mechanism of Electrochemical Hydride Transfer to CO2 [0.03%]
催化剂质子化改变电化学 hydride 向二氧化碳转移的机制
