DISSERTATION THESIS

Graphene Oxide and Carbon Nanotubes in Powder and Paper Form, Decorated with Silver and Palladium Nanoparticles @phdthesis{cd60a2eae5ea46b49416dd2a3c43fd8b, title = "Graphene Oxide and Carbon Nanotubes in Powder and Paper Form, Decorated with Silver and Palladium Nanoparticles", abstract = "This PhD project developed a novel way to create materials by combining carbon-nanostructures with silver or palladium nanoparticles in an environmentally friendly manner. Why is this important? These hybrid materials are valuable in many fields, such as creating paints that kill bacteria, developing materials to clean the environment, and designing better tools for energy storage and use. For example, silver hybrids can kill harmful bacteria or detect diseases, while palladium ones can speed up chemical reactions.Traditionally, making such materials involves using harmful chemicals and creating a lot of waste, which is bad for the environment. This project focused on fixing that by following {"}green chemistry{"} principles, which aim to reduce harm and waste during the process.Here{\textquoteright}s how it worked: Carbon nanomaterials like graphene oxide and multi-walled carbon nanotubes were used as the base. Normally, attaching silver or palladium nanoparticles directly to these surfaces is challenging and doesn{\textquoteright}t give the best performance results. However, by coating the carbon surfaces with special molecules called “amines”, the nanoparticles attach much better and more evenly. This made the hybrid materials more effective and efficient for their intended uses.", author = "{Rodriguez Otamendi}, Dinorah", year = "2025", doi = "10.33612/diss.1209236352", language = "English", publisher = "University of Groningen", school = "University of Groningen", } .

JOURNAL ARTICLE

Eco-friendly synthesis of graphene oxide–palladium nanohybrids @article{e243c387a5ba46549bde99de68b886af, title = "Eco-friendly synthesis of graphene oxide–palladium nanohybrids", abstract = "Nanostructured hybrids of graphene oxide and palladium were fabricated by means of one-step solvent-free gas phase treatment of graphene oxide with the aliphatic amines 1-octadecylamine and 1,8-diaminooctane, followed by in situ decoration with palladium in the liquid medium using palladium chloride as the precursor and citric acid as a mild and environmentally friendly stabilizing and reducing agent. The proposed synthesis method represents an eco-friendly alternative for obtaining nanohybrids of graphene oxide and palladium nanoparticles under mild conditions. Spectroscopic studies evidenced -COOH group derivatization of graphene due to the amidation reaction; transmission electron microscopy demonstrated the formation of nanometer-sized crystalline palladium particles and evidenced that the diamine-functionalization results in a larger particle sizes than observed for monoamine- or non-functionalized substrates. The hybrids obtained have a slightly lower thermal stability than pristine graphene oxide.", keywords = "Characterization, Eco-friendly approach, Graphene oxide, Nanohybrids, Palladium nanoparticles, Solvent-free functionalization", author = "Rodr{\'i}guez-Otamendi, {Dinorah I.} and Monserrat Bizarro and V{\'i}ctor Meza-Laguna and Edgar {\'A}lvarez-Zauco and Petra Rudolf and Basiuk, {Vladimir A.} and Basiuk, {Elena V.}", note = "Funding Information: Financial support from the National Autonomous University of Mexico (UNAM; grant DGAPA-IN100821 ) is greatly appreciated.
