Catalytic Pyrolysis of Plastics over Maghemite-Impregnated Mesocellular Foam using Induction Heating

Luing Wong Syie, Sabino Armenise, B. Nyakuma Bemgba, Soon Ng Pang, Hau Lee Chia, Anna Bogush, Franck Launay, Evgeny Rebrov, Marta Munoz

Pyrolysis is a key technology that converts unrecyclable end-of-life plastics into value-added products. Nevertheless, the high energy consumption during plastic pyrolysis limits the economic feasibility of a scaled-up process. Development of an energy-efficient plastic pyrolysis process is…

Palladium Nanowires Synthesized in Hexagonal Mesophases: Application in Ethanol Electrooxidation

Faygal Ksar, Geetarani Surendran, Laurence Ramos, Bineta Keita, Louis Nadjo, Eric Prouzet, Patricia Beaunier, Agnes Hagege, Fabrice Audonnet, Hynd Remita

Palladium nanowires (of length a few tens of nanometers) are synthesized in a hexagonal mesophase formed by a quaternary system (Pd-doped water, surfactant, cosurfactant, and oil) by electron beam irradiation. The mesophases can be doped by high concentrations of palladium (0.1 M) without any…
