Interfacial hydrogen bonding-involved electrocatalytic ammonia synthesis on OH-terminated MXene

In Situ/Operando Methods for Understanding Electrocatalytic Nitrate Reduction Reaction

“…synthesized oxygen‐functionalized Ti 3 C 2 MXene (Of‐TiMX) and analyzed the surface state of Of‐TiMX by in situ Raman spectroscopy during the reaction. [ 113 ] With the increase of the applied potential, the peak corresponding to NO 3 − gradually disappeared and a characteristic peak of OH appeared. The in situ Raman results indicated that the basal planes of Of‐TiMX were covered by hydroxyl groups under the electrocatalytic conditions.…”

Hydrogen-bonding enables two-dimensional metal/semiconductor tunable contacts approaching the quantum limit and the modified Schottky–Mott limit simultaneously

“…Hydroxylterminated MXene has been experimentally demonstrated to have good electrical conductivity and an ultra-low work function (2.28 eV) close to that predicted by theory, 34,35 and has been maturely used for chemical energy storage applications. 36,37 Here, the close hydrogen-bonding contacts are representatively demonstrated in recently successfully prepared promising semiconducting TMN monolayer MA 2 N 4 (M = Mo, W, etc. ; A = Si, Ge, etc.)…”

Recent advances in electrocatalytic NOx reduction into ammonia

“…[44][45][46][47][48][49] In addition, NO 3 À /NO 2 À to NH 3 production proceeds through the formation of 'NO' as a key intermediate. 50,51 Besides, NO 3 À and NO 2 À electroreductions are liquid phase reactions, so it would require additional expenses and systems to separate the electrochemically synthesized NH 3 from the electrolyte. In contrast, EAS through the NORR is advantageous for practical implementation as the NORR can be conducted in the gas phase using a membrane electrode assembly, and the present gas separation and liquefying units in HBP plants can be reused.…”
