Synergistic photocatalytic degradation of methylene blue and ibuprofen using Co₃O₄-Decorated hexagonal boron nitride (hBN) composites under Sun-like irradiation Bouziani, Mariam; Bouzıanı, Asmae; Hsini, Abdelghani; Bianchi, Claudia L.; Falletta, Ermelinda; Di Michele, Alessandro; Çelik, Gökhan; Hausler, Robert (2025-02-01) In this study, we report the synthesis and photocatalytic performance of Co₃O₄-decorated hexagonal boron nitride (hBN) composites for degrading methylene blue (MB) and ibuprofen (IBF) under sunlight irradiation. Using a dr...
Chemical upcycling of polyolefins into liquid refinery feedstock from the circularity and chemical engineering aspects Aydogdu, Arzum Ceren; Erkmen, Berrak; Suerkan, Ali; Ezdesir, Ayhan; Guliyev, Bilal; Çelik, Gökhan (2024-10-01) Three quarters of all plastics produced each year are discarded to landfill after a single use without proper waste management practices, causing a global environmental crisis: waste plastics suffocating our world at enorm...
Insights into Reaction Mechanisms in Liquid Metals from Density Functional Theory: CH4 Pyrolysis in BiNiX (X = Cu, Al) Molten Metals as a Case Study Erbasan, Arda; Toffoli, Hande; Toffoli, Daniele; Gökalp, İskender; KARDAŞ, GÜLFEZA; Çelik, Gökhan (2024-04-22) Pyrolysis of methane using molten metal catalysts in bubble column reactors presents a cleaner and coking-free alternative for hydrogen production from natural gas due to its lack of direct CO2 emissions. Bubble column rea...
Effect of Pt nanoparticle size on resistance to chloride-induced inhibition for hydrodechlorination of trichloroethylene in water Karahan, Selin; Çelik, Gökhan (2024-04-01) Catalysts used for hydrodechlorination (HDC) of trichloroethylene (TCE) undergo partial or complete loss of catalytic activity due to inhibition by inevitable reaction product HCl. Changing the size of Pt NPs could be used...
Nonoxidative dehydrogenation of propane using boron-incorporated silica-supported Pt Sites synthesized by atomic layer deposition Çelik, Gökhan (2024-01-01) Nonoxidative dehydrogenation of propane to propylene using Pt-based supported catalysts is an active research area in catalysis because catalyst attributes of Pt sites can be controlled by careful design of active sites. O...

Atık Poliolefinlerden Rafineri Girdisine Uygun Hammadde Üretilmesi: Kimyasal Geri Dönüşüm için Katalitik ve Katalitik Olmayan Teknolojilerin Karşılaştırılması ERKMEN, BERRAK; Ezdeşir, Ayhan; Çelik, Gökhan (2023-09-07)
Düzensiz Ortamlarda Reaksiyon Dinamiği Teorisi: BiNiX Üçlü Metal Alaşımları Kullanılarak CH4 gazından H2 eldesi Toffoli, Hande; Erbasan, Arda; Sökmen, Uğur; Eroğlu, Esra; Mutlu, Rasiha Nefise; KARDAŞ, GÜLFEZA; Gökalp, İskender; Çelik, Gökhan (2023-04-28)
Ternary Polyaniline@Bi2O3-BiOCl Nanocomposites as Innovative Highly Active Photocatalysts for the Removal of the Dye under Solar Light Irradiation Bouzıanı, Asmae; Yahya, Mohamed; Bianchi, Claudia L.; Falletta, Ermelinda; Çelik, Gökhan (2023-2-01) Ternary PANI@Bi2O3-BiOCl nanocomposites were successfully synthesized during the oxidative polymerization of aniline monomer in the presence of Bi2O3. PANI@Bi2O3-BiOCl nanocomposites were characterized by several analytica...
Can Pyrolysis Oil Be Used as a Feedstock to Close the Gap in the Circular Economy of Polyolefins? Erkmen, Berrak; Ozdogan, Adem; Ezdesir, Ayhan; Çelik, Gökhan (2023-2-01) Plastics are engineering marvels that have found widespread use in all aspects of modern life. However, poor waste management practices and inefficient recycling technologies, along with their extremely high durability, ha...
