Currently, the global market share for H<sub>2</sub>O<sub>2</sub> is around 4 billion US$ and is expected to grow by about 5.2 billion US$ by 2026. Traditional synthesis of H<sub>2</sub>O<sub>2</sub> via the anthraquinone method is associated with the generation of substantial chemical waste as well as the requirement of a high energy input. In this respect, the oxidative transformation of pure water is a sustainable solution to meet the global demand. In fact, several photocatalysts have been developed to achieve this chemistry. However, 97% of the water on our planet is seawater, and it contains 3.0–5.0% of salts. The presence of salts in water deactivates the existing photocatalysts, and therefore, the existing photocatalysts have rarely shown reactivity toward seawater. Considering this, a sustainable heterogeneous photocatalyst, derived from hydrolysis lignin, has been developed, showing an excellent reactivity toward generating H<sub>2</sub>O<sub>2</sub> directly from seawater under air. In fact, in the presence of this catalyst, we have been able to achieve 4085 μM of H<sub>2</sub>O<sub>2</sub>. Expediently, the catalyst has shown longer durability and can be recycled more than five times to generate H<sub>2</sub>O<sub>2</sub> from seawater. Finally, full characterizations of this smart photocatalyst and a detailed mechanism have been proposed on the basis of the experimental evidence and multiscale/level calculations.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Lignin-supported heterogeneous photocatalyst for the direct generation of H<sub>2</sub>O<sub>2</sub> from seawater","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-20 01:32:51.016389","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2023-08-14","DateCreate":"2022-06-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000763125900023","VABBcode":null,"OpenAcc":0,"DOI":"10.1021/jacs.1c10786"},"refs":null,"anarec":{"AnaID":352740,"PubliDate":2022,"Pagination":"2603-2613","XtraPublOfAnaID":null,"ISBN":null,"Volume":"144","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43303,"SerRR":"Journal of the American Chemical Society.
