A tutorial guide and detailed summary of CO<sub>2</sub>reduction with Cu-based heterogeneous electrocatalysts for newcomers to the field.
Developing an efficient and reliable catalytic protocol to access atropisomeric compounds, especially those bearing five-membered heteroaryl structures with lower rotation barriers, is a challenging task. Here, we disclose unprecedented atropenantioselective Barton–Zard reaction via central-to-axial chirality transfer strategy, by employing α-substituted nitroolefins β-ortho-substituted (hetero)aryl group α-isocyano substrates various electron-withdrawing groups, under the catalysis of Ag2O...

Abstract Fundamental understanding of the influence so‐called spectator electrolyte species on catalytic activity electrodes is considered as a relatively novel direction in electrocatalysis. Numerous recent examples show that seemingly inert components drastically performance centers. Even alkali metal cations aqueous electrolytes at high pH values can change reaction turnover frequency by orders magnitude, depending their nature, from Li + to Cs . Here, we use several electrodes, namely...

Indoline dyes exhibit impressive short-circuit photocurrent (JSC) but show generally low open-circuit voltage (VOC) in dye-sensitized solar cells (DSCs). To retard charge recombination DSCs, four indoline (XS41, XS42, XS43, and XS44) featuring, respectively, dipropylfluorene, hexyloxybenzene, tert-butylbenzene, hexapropyltruxene electron donors, have been engineered.
