科学家开发了新的方法来从茶和咖啡残留物中生产H2O2

H₂o₂（（hydrogen peroxide) is an essential substance with a wide range of uses. However, the existing method for producing H₂o₂成本高昂，会产生大量的废物，使其不可持续。

一群日本研究人员创建了H₂o₂from waste coffee grounds and tea leaves and then illustrated its industrial application. Their innovative approach proved to be simple, cost-effective, and most notably, sustainable.

Coffee and tea are two of the most widely consumed liquids on the planet. Large volumes of coffee grounds and tea leaves are produced as a result of the widespread use of these beverages, which are often dumped as garbage.

但是，这些未充分利用的生物质资源有可能创建各种重要化合物。多酚是在茶和咖啡中发现的一种化学物质，可以产生过氧化氢（H₂o₂）。

H₂o₂has a high commercial value since it is used in the oxidation of a variety of substances. The oxidation process is usually conducted by the enzyme P450 peroxygenase, although it cannot happen without H₂o₂。

许多重要的化合物是通过这些氧化过程制成的。H₂o₂目前是使用一种称为蒽醌工艺的不可持续技术制造的，它不仅是能源密集型的，而且浪费了，强调了对更绿色，更生态友好的替代方案的需求。

其他生产H的方法₂o₂使用酶或光的成本更高，因为它们需要催化剂和额外的化学物质。

With these concerns in mind, a group of Japanese scientists led by Associate Professor Toshiki Furuya and Mr. Hideaki Kawana ofTokyo University of Science，以及奈良女子大学的Yuki Honda博士，都设计了一种新方法来生产H₂o₂。

Their product is made from the remains of brewed tea and coffee, which are referred to as spent coffee grounds (SCG) or tea leaf residue (TLR).

Given their polyphenol content, we predicted that SCG and TLR could be used to produce hydrogen peroxide.

Their study, which was published inACS Omega6月1日^英石，2022年，概述了他们有效的H₂o₂从这些未充分利用的生物量资源中，证明了它们的预后。

团队的制造技术是在磷酸钠缓冲液中添加咖啡研磨和茶叶，然后在摇动溶液时孵育溶液。SCG和TLR与分子氧反应形成H₂o₂在缓冲区的情况下。

The researchers also looked at the possibility of utilizing this H₂o₂制作其他重要的化合物。由于新鲜合成的H，Russig的蓝色的生产变得更加容易₂o₂。

此外，在存在过氧酶的情况下（一种使用H催化氧化反应的酶₂o₂），TLR-和SCG衍生的H₂o₂可以自由与称为苯乙烯的分子反应，以产生氧化苯乙烯（在医学中有多种应用）和苯乙醛醛（另一种有用的化合物）。

In comparison to the classic anthraquinone procedure, the team’s innovative strategy of combining SCG and TLR to manufacture H₂o₂被证明是简单，具有成本效益和生态良性的。

Furuya博士概述了：“our method can be used to produce hydrogen peroxide from materials that would otherwise have been discarded. This could further result in new ways to synthesize industrial chemicals like styrene oxide, opening up new applications for these unused biomass resources.透明

结果，这些发现为可持续性H开辟了新的途径₂o₂从茶和咖啡垃圾中产生的是最出乎意料的来源。
