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.

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.

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.

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.
