Effect of Boron Doping On Graphene Oxide for Ammonia Adsorption

Boron doped graphene oxide (B-GO) is a highly effective adsorbent for ammonia due to the high density of strong Lewis acid sites arising from the boron. GO was doped by various amounts of boron described as xB-GO (x= 1.0, 3.0, and 5.0). B-GO was successful ...

Polystyrene CuO/Cu2O uniform films inducing MB-degradation under sunlight

César Pulgarin, Juan Kiwi, Sami Rtimi, Oualid Baghriche

This study reports on a Cu-sputtered film on polystyrene (PS) leading to the discoloration/degradation of methylene blue (MB) under low intensity solar simulated irradiation. Direct current magnetron sputtering (DCMS) was used to graft uniform, adhesive Cu ...

Insight into the catalyst/photocatalyst microstructure presenting the same composition but leading to a variance in bacterial reduction under indoor visible light

César Pulgarin, Juan Kiwi, Sami Rtimi

Insight into two different uniform atomic-scale microstructures of Cu-and Ti-oxides sputtered on polyethylene (PET) presenting different redox properties and a distinct bacterial inactivation dynamics. Co-sputtered (CuOx-TiO2-PET) consists mainly of CuO. I ...

Cu-decorated Raschig-TiO2 rings inducing MB repetitive discoloration without release of Cu-ions under solar light

César Pulgarin, Juan Kiwi, Rosendo Sanjines, Helena Luisa Teixido Pedarros, Laura Victoria Suárez Murillo

The methylene blue (MB) discoloration on innovative photocatalysts made up of Raschig-rings coated by pre-formed TiO2 nanoparticles decorated with CuOx (RR@TiO2-Cu) is presented. The MB-discoloration was drastically accelerated by the subsequent addition o ...

Structural Reversibility and Nickel Particle stability in Lanthanum Iron Nickel Perovskite-Type Catalysts

Davide Ferri, Oliver Kröcher, Debora Foppiano, Andre Heel

Perovskite-type oxides have shown the ability to reversibly segregate precious metals from their structure. This reversible segregation behavior was explored for a commonly used catalyst metal, Ni, to prevent Ni sintering, which is observed on most catalys ...

Hybrid Heterojunctions of Solution-Processed Semiconducting 2D Transition Metal Dichalcogenides

Kevin Sivula, Nestor Guijarro Carratala, Natalie Renuka Banerji, Xavier Adrian Jeanbourquin, Xiaoyun Yu

Exfoliated transition metal dichalcogenides (2D-TMDs) are attractive light-harvesting materials for large-area and inexpensive solar energy conversion given their ability to form highly tolerant heterojunctions. However, the preparation of large-area heter ...

Beyond structure: ultrafast X-ray absorption spectroscopy as a probe of non-adiabatic wavepacket dynamics

Majed Chergui, Simon Neville

The excited state non-adiabatic dynamics of polyatomic molecules, leading to the coupling of structural and electronic dynamics, is a fundamentally important yet challenging problem for both experiment and theory. Ongoing developments in ultrafast extreme ...

Hydrophilic Interaction Between Low-Coordinated Au and Water: H2O/Au(310) Studied with TPD and XPS

Maarten Eduard van Reijzen

In this work, we study the relatively weak H2O Au interaction on the highly stepped and anisotropic (310) surface with temperature-programmed desorption and X-ray photoelectron spectroscopy. Compared to Au(111), we report an enhanced adsorption energy of H ...
