Article Abstract
We report herein on the use of two binuclear cobalt complexes with the ,'-bis(salicylidene)-phenylmethanediamine ligand as catalysts for the H evolution in DMF solution with acetic acid as proton source. Both experimental analyses (electrochemical analysis, spectroscopy analysis) and theoretical analysis (foot-of-the wave analysis) were employed. These catalysts required an overpotential of 470 mV to catalyze the H evolution and generated H gas with a faradaic efficiency of 85-95% as calculated on the basis of after 5 hour bulk electrolysis. The kinetic investigation showed the maximal TOF value of 50 s on the basis of an ECEC mechanism. Two cobalt centers, standing at a long distance of 4.175 Å, operated independently during catalysis without a synergetic effect or cooperation capability.

The development of highly efficient and durable bifunctional catalysts with minimal precious metal usage is critical for advancing proton exchange membrane water electrolysis (PEMWE). We present an iridium-platinum nanoalloy (IrPt) supported on lanthanum and nickel co-doped cobalt oxide, featuring a core-shell architecture with an amorphous IrPtOx shell and an IrPt core. This catalyst exhibits exceptional bifunctional activity for oxygen and hydrogen evolution reactions in acidic media, achieving 2 A cm at 1.

A salient challenge in cancer chemotherapy is the successful delivery of drugs to cancer cells. Therapeutic agents can be delivered to cancer cells in a targeted and efficient manner using nanoparticles (NPs). Herein, we present the molecular characterization of a novel binuclear Co(II) complex with octahedral geometry based on Schiff base from dehydroacetic acid and piperazine derivatives.

In this work, we report a new heterogeneous catalyst for the methoxycarbonylation of epoxyethane (EO) to methyl 3-hydroxypropanoate (3-HPM), achieving good yields and recyclability of up to three times with no obvious loss in catalytic activity. The catalysts were prepared through an effective strategy to anchor active cobalt carbonyl species to functionalized silica-based molecular sieves. The successful grafting of functional ligand and cobalt carbonyl cluster was evident through Si-MAS NMR and FT-IR studies.

Dual-atom catalysts featuring synergetic dinuclear active sites, have the potential of breaking the linear scaling relationship of the well-established single-atom catalysts for oxygen reduction reaction; however, the design of dual-atom catalysts with rationalized local microenvironment for high activity and selectivity remains a great challenge. Here we design a bisalphen ladder polymer with well-defined densely populated binuclear cobalt sites on Ketjenblack substrates. The strong electron coupling effect between the fully-conjugated ladder structure and carbon substrates enhances the electron transfer between the cobalt center and oxygen intermediates, inducing the low-to-high spin transition for the 3d electron of Co(II).

The development of molecular composite photocatalysts for cost-effective, sacrificial-reagent-free CO reduction is desirable but challenging. Herein, we employed an encapsulation strategy to encapsulate the binuclear cobalt complex (CoL) within NH-MIL-125 and synthesized a range of MOF-based composites with varying cobalt content for photocatalytic CO reduction. The photocatalytic results showed that the catalytic performance increased with the increase in CoL content, reaching a rapid CO generation rate of 27.
