An electrochemical cell with molten hydroxide and a Pd membrane actively extracts H2 and thereby boosts ammonia and methylcyclohexane conversion, while also delivering purified H2 ready for use.

Electrochemical polarization is now known to play a key role in thermochemical catalysis at solid–liquid interfaces. However, existing frameworks cannot account for why even nonpolar, nonfaradaic reac...

Several thermochemical redox reactions have been shown to operate via the coupling of electrochemical half-reactions. Here, scanning electrochemical cell microscopy is employed to image the variations...

The rate of interfacial proton-coupled electron transfer (I-PCET) to a graphite-conjugated carboxylic acid electrode depends on the concentration of nominally innocent supporting NaClO4 electrolyte. T...

Heterolytic hydrogenations are a key reaction class that includes CO2 reduction to formate and NADH regeneration, yet the mechanism remains unclear. Now it has been shown that this class of thermochemical reactions proceeds through an electrochemical mechanism, with polarization-driven, interfacial hydride transfer as the rate-determining step.

Hydride transfer is an essential elementary reaction across the chemical value chain, but there are limited methods available for quantifying thermodynamic hydricity (ΔGH–), particularly among main gr...

Upending a long-held supposition, MIT researchers discovered that a common catalyst works by cycling between two different forms. The finding could lead to improved catalysts for industrial reactions.

Homogeneous and heterogeneous catalysis work concurrently in a chemical process

Presently, mechanistic paradigms in catalysis generally posit that the active species remains either homogeneous or heterogeneous throughout the reaction. In this work, we show that a prominent indust...

Interfacial polarization influences catalytic reactions occurring at solid–liquid interfaces, but its measurement was previously limited to conductive materials. Now redox-active molecules enable elec...
