Synthesis and physico–chemical research of 18–molibdophosphate and its reduced forms [PDF]

open access: yes, 2018
У деяких роботах стабільність гетерополікомплекса структури Доусона P2Mo18O626– у водних розчинах поставлена під сумнів. Тому дослідження стійкості водних розчинів цієї речовини є актуальним. З цією метою проведено синтез 18 - молібдодифосфату.

Directed Charge Transfer‐Driven Efficient Photocatalytic Hydrogen Production in Dual S‐Scheme WS2/Co9S8/ZnCdS Heterojunction

open access: yesCarbon Energy, EarlyView.
The photocatalytic hydrogen evolution reaction (HER) activity of the polyoxometalate (POM)‐derived dual S‐scheme heterojunction photocatalyst WS2/Co9S8/ZnCdS reaches a value as high as 15.66 mmol g−1 h−1 under visible light (λ ≥ 420 nm), providing a straightforward approach for the development of dual S‐scheme heterojunctions to enhance the efficiency ...

Redox‐Mediating Mo2C Nanoparticles Confined Within Nitrogen‐ and Phosphorus‐Codoped Amorphous Carbon Matrix for Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional interlayer composed of Mo2C nanoparticles embedded in a nitrogen‐ and phosphorus‐doped amorphous carbon matrix on graphene is developed via electrostatic self‐assembly and thermal transformation. The resulting architecture suppresses the shuttle effect, improves electrical conductivity, and facilitates redox conversion kinetics ...
