一般描述

氯化金（III）水合物（HAuCl4）可用作合成金纳米颗粒和大多数共轭有机分子的 p 型掺杂剂的前体。.掺杂导致晶格膨胀，并由于大量电荷载流子的形成而增强导电性。

应用

氯化金（III）水合物可用于通过与尿素的沉积沉淀来制备 TiO2负载的 Au 基光催化剂。这些催化剂在水裂解反应中表现出较高的产氢量和产氢速率。

共轭聚噻吩膜可以通过使用 HAuCl4 作为掺杂剂的溶液掺杂方法来制备。这些高导电聚合物薄膜可应用于蒸汽传感和有机电子领域。

通过使用不同的还原剂，如 NaBH4、葡萄糖和聚（丙烯亚胺）树枝状聚合物，可以通过还原 HAuCl4来制备金纳米颗粒。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How can I determine the number of hydrates present in Product 254169, Gold (III) chloride hydrate?

    To determine the number of hydrates, you can use the following formula:   % of the metal = [(MW of metal) (# of metal atoms)] / [(MW of anhydrous product) + (x * 18g/mol)]Solving for x: x = [[(MW of metal)(#metal atoms)] - [(%of metal in product)(MW of anhydrous product)]] / [(% of metal in product) (18 g/mol)] 

  4. What is n Product 254169, Gold (III) chloride hydrate soluble in?

    This product is soluble in water, ethanol, and ether.  Unfortunately we do not have any recorded concentrations.

  5. What is the melting point of n Product 254169, Gold (III) chloride hydrate?

    We have never determined the melting point, however we do have a note indicating that this compound will decompose when melted.  Also the 13th Edition of the chemicals encyclopedia published by the Royal Society of Chemistry states that this compound will decompose on strong heating to form chlorine gas, hydrochloric acid gas, and metallic gold.

  6. What is the reported purity of Product 254169, Gold (III) chloride hydrate based on, chemical or metal purity?

    The purity (99.999%) is not the chemical purity, but rather the purity based on trace metal content.  In the case of 99.999% a maximum of 20ppm total metallic impurities would be allowed.

  7. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.
