Redox Promoted Rapid and Deep Reconstruction of Defect-Rich Nickel Precatalysts for Efficient Water Oxidation.

Understanding the reconstruction mechanism to rationally design cost-effective electrocatalysts for oxygen evolution reaction (OER) is still challenging. Herein, a defect-rich NiMoO precatalyst is used to explore its OER activity and reconstruction mechanism. In situ generated oxygen vacancies, distorted lattices, and edge dislocations expedite the deep reconstruction of NiMoO to form polycrystalline Ni (oxy)hydroxides for alkaline oxygen evolution.

Dual Interface Compatibility Enabled via Composite Solid Electrolyte with High Transference Number for Long-Life All-Solid-State Lithium Metal Batteries.

The development of solid-state electrolytes (SSEs) effectively solves the safety problem derived from dendrite growth and volume change of lithium during cycling. In the meantime, the SSEs possess non-flammability compared to conventional organic liquid electrolytes. Replacing liquid electrolytes with SSEs to assemble all-solid-state lithium metal batteries (ASSLMBs) has garnered significant attention as a promising energy storage/conversion technology for the future.

Symbiotic composite composed of MoS and pelagic clay with enhanced disinfection efficiency.

Molybdenum disulfide (MoS) has attracted increasing attention as a promising photocatalyst. In addition to its application in photocatalytic hydrogen production and pollutant degradation, MoS is also used in water disinfection. However, its poor disinfection performance limits its practical utility.

Electrochemical Fixation of Nitrogen by Promoting N Adsorption and N-N Triple Bond Cleavage on the CoS/MoS Nanocomposite.

An electrochemical N reduction reaction (NRR), as an environmentally benign method to produce NH, is a suitable alternative to substitute the energy-intensive Haber-Bosch technology. Unfortunately, to date, it is obstructed by the lack of efficient electrocatalysts. Here, a CoS/MoS nanocomposite with CoS nanoparticles decorated on MoS nanosheets is fabricated and adapted as a catalyst for the NRR.
