Summary: The kinetic properties of Ni(II) in FLiNaK molten salt were investigated using various electrochemical techniques. The reduction of Ni(II) to Ni(s) was found to be a single step, two-electron transfer process. Diffusivity values were calculated using different equations and methodologies, with a range of 3.27 x 10(-7)-3.04 x 10(-6) cm(2) s(-1) and an activation energy of 62-104 kJ mol(-1). The variations in the estimated kinetic properties may be attributed to the assumptions made in the theoretical models regarding reversibility and unit activity during Ni metal deposition.

Summary: Dimerized 3-substituted 2-oxindoles were synthesized using TEMPO as a redox mediator and TEMPO+ as an in situ generated electrocatalyst. Two-electron and one-electron transfer pathways were observed depending on the oxidation potentials of the 2-oxindoles. This study also demonstrated the use of electron-transfer rate measurement, prevention of electrode passivation, electrolyte recovery, and mild reaction conditions in greener electro-organic synthesis. Finally, an efficient electrochemical oxidation strategy was employed for the total synthesis of two dimeric alkaloids.

Summary: We synthesized four MOF-derived nitrogen and oxygen co-doped ultramicroporous/microporous carbon (MNOUCs) at different carbonization temperatures and investigated their potential for CO2 capture. MNOUC-900, carbonized at 900 degrees C, exhibited the highest surface area and ultra-micropore volume, resulting in the highest CO2 uptake of 4.65 mmol g(-1) at 0 degrees C and 1 bar. In contrast, MNOUC-600 showed the highest CO2/N-2 selectivity of 31. The CO2 uptake was found to be correlated with ultramicropore volume, while selectivity improved with increasing basic nitrogen functionalities. Dynamic CO2 uptake experiments confirmed the efficiency of MNOUC-900 as a CO2 adsorbent.

Summary: In this study, we report the first report of 1,2-difunctionalization of C-C multiple bonds using electrochemical gold redox catalysis. By adopting the electrochemical strategy, we harnessed the inherent π-activation and cross-coupling reactivity of gold catalysis to develop the oxy-alkynylation of allenoates under external-oxidant-free conditions. Detailed mechanistic investigations, including P-31 NMR, control experiments, mass studies, and cyclic voltammetric (CV) analysis, have been performed to support the proposed reaction mechanism.

Summary: In this study, a novel water electrolysis catalyst in the form of a composite of pillared metal-organic framework (MOF) and graphene (G), denoted as Ni2Co(bdc)(2)D@G, was proposed. The electrochemical analysis showed that the Ni2Co(bdc)(2)D@G composite exhibited superior catalytic activity compared to Ni2Co(bdc)(2)D, with lower overpotential and higher current density. This improvement in performance was attributed to the synergistic effects between the MOF and graphene, the high surface area of the electrocatalyst, and the π-π interaction between the MOF and G.

Summary: A series of cerium-doped CoFe-layered double hydroxide materials were synthesized and used for the oxygen evolution reaction. The highest cerium doping (CoFeCe2) exhibited significantly higher mass activity, turnover frequency, and TOFEIS compared to undoped CoFe-LDH. Cerium doping increased the roughness factor, surface area, and pore volume, and resulted in a narrow mesoporous distribution.
