Activated Co in Thiospinel Boosting LiCO Decomposition in Li-CO Batteries.

Catalytic reactions mainly depend on the adsorption properties of reactants on the catalyst, which provides a perspective for the design of reversible lithium-carbon dioxide (Li-CO) batteries including CO reduction (CORR) and CO evolution (COER) reactions. However, due to the complex reaction process, the relationship between the adsorption configuration and CORR/COER catalytic activity is still unclear in Li─CO batteries. Herein, taking CoS as a model system, nickel (Ni substitution in the tetrahedral site to activate cobalt (Co) atom for forming multiatom catalytic domains in NiCoS is utilized.

Steering the Orbital Hybridization to Boost the Redox Kinetics for Efficient Li-CO Batteries.

The sluggish CO reduction and evolution reaction kinetics are thorny problems for developing high-performance Li-CO batteries. For the complicated multiphase reactions and multielectron transfer processes in Li-CO batteries, exploring efficient cathode catalysts and understanding the interplay between structure and activity are crucial to couple with these pendent challenges. In this work, we applied the CoS as a model catalyst and adjusted its electronic structure by introducing sulfur vacancies to optimize the d-band and p-band centers, which steer the orbital hybridization and boost the redox kinetics between Li and CO, thus improving the discharge platform of Li-CO batteries and altering the deposition behavior of discharge products.

Recycled Tandem Catalysts Promising Ultralow Overpotential Li-CO Batteries.

Lithium-carbon dioxide (Li-CO ) batteries are regarded as a prospective technology to relieve the pressure of greenhouse emissions but are confronted with sluggish CO redox kinetics and low energy efficiency. Developing highly efficient and low-cost catalysts to boost bidirectional activities is craved but remains a huge challenge. Herein, derived from the spent lithium-ion batteries, a tandem catalyst is subtly synthesized and significantly accelerates the CO reduction and evolution reactions (CO RR and CO ER) kinetics with an in-built electric field (BEF).

Energy Band Engineering Guided Design of Bidirectional Catalyst for Reversible Li-CO Batteries.

Li-CO batteries arouse great interest in the context of carbon neutralization, but their practicability is severely hindered by the sluggish CO redox reaction kinetics at the cathode, which brings about formidable challenges such as high overpotential and low Coulombic efficiency. For the complex multi-electron transfer process, the design of catalysts at the molecular or atomic level and the understanding of the relationship between electron state and performance are essential for the CO redox. However, little attention is paid to it.

Engineering the interfacial orientation of MoS/CoS bidirectional catalysts with highly exposed active sites for reversible Li-CO batteries.

Sluggish CO reduction reaction (CORR) and evolution reaction (COER) kinetics at cathodes seriously hamper the applications of Li-CO batteries, which have attracted vast attention as one kind of promising carbon-neutral technology. Two-dimensional transition metal dichalcogenides (TMDs) have shown great potential as the bidirectional catalysts for CO redox, but how to achieve a high exposure of dual active sites of TMDs with CORR/COER activities remains a challenge. Herein, a bidirectional catalyst that vertically growing MoS on CoS supported by carbon paper (V-MoS/CoS@CP) has been designed with abundant edge as active sites for both CORR and COER, improves the interfacial conductivity, and modulates the electron transportation pathway along the basal planes.

Transformation between 2D covalent organic frameworks with distinct pore hierarchy via exchange of building blocks with different symmetries.

Transformation between 2D covalent organic frameworks (COFs) via exchange of molecular building blocks with different symmetries has been realized, which gives rise to the conversion between 2D COFs with distinct pore hierarchy. This type of monomer replacement has expanded the scope of the building-unit-exchange-based COF-to-COF transformation strategy.

Protective effects of lycopene on kainic acid-induced seizures.

Lycopene (LCP) is a carotenoid that protects against many diseases by alleviating oxidative stress. However, the effect of LCP on epileptic seizures has not been examined well in previous studies. In the current work, we employed kainic acid (KA) to induce experimental epileptic seizures in mice, and investigated the function of LCP during this process.
