This is because the OER must overcome a high electrochemical overpotential (thermodynamic potential) due to its complexity and the four protons and four electrons it involves. While noble-metal-based electrocatalysts can lower this potential, they are among the rarest metals in the Earth’s crust, expensive, and not suitable for sustainable use. Herein, we develop a facile, cost-effective synthetic approach to an inexpensive, metal-free OER electrocatalyst by preparing defective graphene nanosheets and then selectively functionalizing them with phosphorous acid species. The electrocatalytic activity of the resulting metal-free, phosphorus-doped (P-doped) graphene toward OER surpasses those of previously reported metal-free graphene-based electrocatalysts. Notably, the synthesized catalyst requires a lower overpotential to catalyze the reaction, which can be attributed to its increased surface area and reactive defect/active sites associated with the phosphorus dopants present on it. The material also shows excellent stability, maintaining its performance as well as its morphology and structures for hours in an alkaline electrolyte. The present work opens opportunities for the design and synthesis of heteroatom-doped graphene (nanocatalyst) for challenging environmentally benign, energy-related chemical transformations.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"27 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142753593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their water and oil resistance are typically achieved by using either per- and polyfluoroalkyl substances (PFAS), which are harmful and persistent in the environment, or plastic coatings, which exacerbate the plastic pollution issue. Hence, safe and ecofriendly water- and oil-resistant materials are a crucial need. Emulating natural plant properties, we applied a seamless lignin film on paper via the hot-pressing method. By varying parameters such as lignin coating weight (10–40 g/m<sup>2</sup>), hot-pressing pressure (1–5 MPa), temperature (120–180 °C), and moisture content (10–50 wt %) of lignin micro and nanoparticles (LMNP) suspension before hot-pressing, we determined that 40 g/m<sup>2</sup> of lignin coating weight applied at 3 MPa pressure, 160 °C temperature, and 30 wt % moisture content are the optimal condition. This yielded a lignin layer with exceptional waterproofing (100 min) and oil resistance (25 min).
