▼a The conversion of nitrogen into ammonia in an ambient environment poses a major challenge for chemists. From a thermodynamic perspective, electrochemical nitrogen reduction in water is feasible, but most attempts so far have very low selectivity |
520 | |
▼a We investigate an alternative approach to electrochemically synthesizing ammonia from water and dissolved nitrogen gas. Instead of capturing nitrogen molecules and transferring electrons at the solid-liquid interface, we attempt to inject electr |

▼a Serendipitously, while exploring the tunneling behavior of n+ -Si/SiO2, we found that n+-Si/SiO2 as an insulator-covered electrode can conduct electricity under remarkably mild conditions in an electrochemical cell. It seems counterintuitive th |

▼a Lastly, we constructed a transistor set-up using a n+-Si/SiO 2/Au electrode with two circuits in parallel and the gold layer as common ground. In the first circuit, n+-Si/SiO2/Au is a tunnel junction that acts as a hot electron emitter to provid |

▼a Unfortunately, we were unable to make ammonia at quantifiable levels using any of the devices and routes mentioned above, presumably because of extreme competition from hydrogen evolution on the surface of the devices or in bulk solution. We des |
