Summary: In this study, a slightly nitrogen-doped carbon catalyst was synthesized using a simple method. The catalyst showed low overpotential and high selectivity in producing H2O2 in an acidic electrolyte, and stable H2O2 production was achieved. The relationship between the surface content of C-O/C-N and C=O species and the H2O2 partial current suggested that C atoms act as active sites for 2e-ORR to H2O2. The catalyst, with its inexpensive starting materials and excellent catalytic performance, may contribute to the development of an affordable, safe, and direct electrochemical process for O2-to-H2O2 conversion.

Summary: N-2 fixation is traditionally achieved by transition metal systems through back donation from the d orbitals to activate N-2, which is rare for main group compounds. However, this study shows that borane compounds with weak B-X bonds can mimic TM systems and fix and activate N-2. Based on these findings, stable silylborane compounds were designed for N-2 fixation and activation under mild reaction conditions.

Summary: The hydrogenolysis of C-C bonds is a crucial process in the petroleum industry, but it often requires high temperatures and pressures with limited selectivity. However, a borenium complex has been discovered to catalyze the selective hydrogenolysis of unstrained C(aryl)-C(alkyl) bonds at ambient temperature without the need for directing groups. Mechanistic studies have revealed that the reaction involves the synergistic activation of dihydrogen by the borenium complex and alkylarenes, followed by retro-Friedel-Crafts reaction to cleave the C(aryl)-C(alkyl) bonds. The synthetic utility of this protocol has been demonstrated by converting post-consumer polystyrene into valuable benzene and phenylalkanes with a mass recovery rate of over 90%.

Summary: We provide design criteria for dilute ether electrolytes that can support reversible graphite anodes by tailoring solvation structures and thermodynamic properties. Our redesigned electrolyte consisting of 1,3-dioxolane (DOL) solvent and lithium bis(fluorosulfonyl)imide (LiFSI) salt weakens Li-solvent interaction and results in an inorganic-rich solid electrolyte interphase, achieving high Coulombic efficiency and capacity retention. The weakly solvated electrolyte maintains desirable transport properties and enables better rate capability than carbonate electrolytes.
