一般說明

铜氧化物(Cu2O、CuO)是具有小带隙能量的p型半导体材料。金属氧化物纳米粒子的高物理和化学稳定性使它们在催化应用中非常有用。这些化合物的结构属于单斜晶系。纳米级氧化铜化合物可通过热等离子体技术进行制备。一项研究已对其抗菌特性进行了报道。[1]

應用

氧化铜纳米颗粒的毒性已有报道。[2][3][4] Cu2O已用于涂覆Cu纳米颗粒(Cu2O NPs)。[5]据报道,氧化铜纳米颗粒被用作锂离子电池的阳极材料,并且由于其高表面反应性已被用作气体传感器。 空心Cu2O NPs已被用于制备核苷,并被其他基团用作叠氮化物-炔烃环加成反应中的催化剂。[6]CuO NP可用作CSe、CTe和CS键形成,以及2-氨基苯并噻唑合成的催化剂。[7]小鼠巨噬细胞对CuO和Cu2O NPs的分子反应已有研究。[8]

Questions

1–3 of 3 Questions  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. 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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. What is the purity of the nanopowder copper catalog N° 544868 ? Thanks in advance

    1 answer
    1. The purity of the copper(II) oxide product is essentially a function of how much copper is present. Product 544868 is listed as 77.0 - 82.6 % on the Certificate of Analysis. Please see the sample Certificate of Analysis: https://www.sigmaaldrich.com/certificates/sapfs/PROD/sap/certificate_pdfs/COFA/Q14/544868-BULKMKCR3494.pdf).

      The minimum 77.0% copper would be 96.4% pure copper oxide and 82.6% would be 103.4% pure. The sample lot is listed as 78.1% copper, which can be extrapolated to be 97.8% pure copper(II) oxide.
