If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

Description générale
Application
- As a starting material to synthesize tungsten nanoparticles[1] and Mo-doped urchin-like W18O49 Nanostructure using the hydrothermal method. The Mo-W18O49 electrocatalyst exhibited excellent electrocatalytic activity toward Hydrogen Evolution Reaction (HER).[2] By doping Mo species into defect-rich W18O49 ultrathin nanowires, it has also been demonstrated to be an excellent candidate for photocatalytic N2 fixation to ammonia.[3]
- To synthesize crystalline mesoporous WO3 with 11 nm pore size utilizing a high-molecular-weight amphiphilic block copolymer as the structure-directing agent. The materials performed admirably in terms of H2S gas sensing.[4]
- To fabricate Tungsten disulfide and WS2/reduced graphene oxide (WS2/rGO) nanosheets by hydrothermal synthesis. The WS2/rGO nanosheets showed exceptional electrocatalytic activity for the hydrogen evolution reaction.
- To produce the WS2-nanoflowers@rGO and nitrogen-doped carbon spheres@WS2 composite as an anode material for enhanced electrode performance in lithium-ion batteries.[5]
- As a dopant to fabricate TiO2 compact layers for perovskite solar cells with enhanced performance.[6]
- As a catalyst to prepare self-healing epoxy composites with microcapsules.[7]
- As a catalyst for transamidation of tertiary alkyl amides.[8]

How is shipping temperature determined? And how is it related to the product storage temperature?
1 réponse-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

Hello. Could you possibly provide me with the average particle size and a brief description of the particle shape? I am looking for small, homogeneous nano-particles. An SEM image would be greatly appreciated. Thank you.
1 réponse-
The particle size of this product is not determined, but is expected to be less than 2 mm. Unfortunately, an SEM image is currently not available.
