This report describes the design of diaminocyclopropenium-phenothiazine hybrid catholytes for non-aqueous redox flow batteries. The molecules are synthesized in a rapid and modular fashion by appending diaminocyclopropenium (DAC) substituent to nitrogen phenothiazine. Combining versatile C-N coupling protocol (which provides access diverse derivatives) with computation structure-property analys...

ConspectusAs electrochemical CO2 reduction studies progress from beaker or H-cell devices operating at low current densities to gas diffusion electrode (GDE)-based that sustain high reaction rates and provide an avenue toward commercialization, the overall system becomes significantly more complex. While may vary for different approaches, it is essential maintain same scientific rigor when anal...

We report an electrochemical reactor that converts 3.0 M KHCO3 into methane at the cathode, and oxidizes water anode. The molar ratio of product to unreacted CO2 gas (defined herein as “methane yield”) was measured be 34% a partial current density 120 mA cm–2. highest previously reported CO2-to-methane yield is 3%. Our achieved this improvement in because it fed with KHCO3, type reactive carbon...
