“…Concerning the doped metal elements, the Mg1s, Fe2p and In3d spectra were reported in Figure except the Al2p which was not detected. A single peak centered at BE of 1304.8 eV was found in Mg1s spectra, evidencing the presence of MgO which could not be reduced in the tested conditions . Similarly, the In3d spectra also contained one single peak at BE of 443.1 eV which originated from metallic In 0 .…”

Effects of Dopants in PtSn/M‐Silicalite‐1 on Structural Property and on Catalytic Propane Dehydrogenation Performance

The various metal-doped Silicalite-1 (MÀ S1, M=Mg, Al, Fe and In) supports were prepared by hydrothermal synthesis method, then were used to disperse the PtSn species through impregnation. The resulting solids were further characterized through XRD, N 2 adsorption/desorption isotherms, XPS, H 2 -TPR, NH 3 -TPD, Raman spectroscopy and TG techniques to investigate the structural property before and after propane dehydrogenation reaction. The results exhibited that the introduction of various metal dopants had profound effects on pore structure, reducibility, acidity and surface content of Pt which was directly related to the activation of propane. And the surface content of Pt acted as the dominant role for converting propane. As a consequence, the maximum initial conversion of propane was obtained over Fe-modified PtSn/FeÀ S1 sample, but it deactivated fast as well because of the coke deposition.

“…In the laboratory, H 2 production is studied from ethanol by steam reforming (SRE), partial oxidation and oxidative steam reforming (OSRE, including autothermal reforming) reactions [82][83][84][85][86], and from CH 4 , by dry reforming (DRM) and oxidative dry reforming (ODRM) reactions [40,[87][88][89][90]. These last reactions are of particular interest because they allow the transformation and valorization of two greenhouse gases (CH 4 and CO 2 ), and also can be applied to fuel cells [90].…”

The development of the future French and European bioeconomies will involve developing new green chemical processes in which catalytic transformations are key. The VAALBIO team (valorization of alkanes and biomass) of the UCCS laboratory (Unité de Catalyse et Chimie du Solide) are working on various catalytic processes, either developing new catalysts and/or designing the whole catalytic processes. Our research is focused on both the fundamental and applied aspects of the processes. Through this review paper, we demonstrate the main topics developed by our team focusing mostly on oxygen- and hydrogen-related processes as well as on green hydrogen production and hybrid catalysis. The social impacts of the bioeconomy are also discussed applying the concept of the institutional compass.

The effects of Cu, Zn, and Mn on CeO2 in ethanol steam reforming for hydrogen production were evaluated. Solid solution catalysts were analyzed by Brunauer‐Emmett‐Teller method, X‐ray diffraction, temperature‐programmed reduction, scanning electron microscopy, and energy dispersive X‐ray. CeMn oxide showed the highest conversion and hydrogen yield. The entrance of Mn to the ceria lattice could enhance the catalyst reducibility. An increase of the Ce/Mn ratio led to high methane selectivity. Mn conducted the reaction to more CO2 generation and was also an effective metal for ethanol steam reforming reaction by adsorbing steam and the ability of oxygen mobility. Ce0.3Mn0.7 oxide provided moderate ethanol conversion and hydrogen yield. The catalyst exhibited higher conversion but lower hydrogen yield by adding Ni.
