Mesoporous materials with high surface area, large pore volume, and adjustable pore size are promising in the fields of adsorption and heterogeneous catalysis. In this work, ordered meso-porous ceria structures were successfully prepared via nanocasting using SBA-15 as a template... |
17 jul 2025 - Green hydrogen production from waste biomass pyrolysis fractions by auto-thermal reforming in a membrane reactor BIOWASTETOH2
Megía, Pedro J.; Lourdes García-Moreno; Vizcaíno, Arturo; Calles, Jose A; CARRERO, ALICIA, 2025, "Bioethanol steam reforming for hydrogen production over Ni‑Cr/SBA 15: Influence of metal loading and Ni/Cr ratio", https://doi.org/10.21950/RPTIHB, e-cienciaDatos, V1
This work examines the influence of metal loading and Ni/Cr ratio of Ni-Cr/SBA-15 catalysts on bioethanol steam reforming for the first time. The characterization of the synthesized samples reveals that higher Cr amounts results in lower Ni crystallite sizes due to the promoting... |

Chirinos Chavez, Carlos Andres; MORENO DE LA CALLE, Alvaro; MEGIA, Pedro J.; Vizcaíno, Arturo; Calles, Jose A; CARRERO, ALICIA, 2025, "Exploring CeO2-doped Co/SBA-15 catalysts for acetic acid oxi-dative steam reforming", https://doi.org/10.21950/7DVG6R, e-cienciaDatos, V1
This work explores the effect of CeO2 incorporation into Co/SBA-15 catalysts on hy-drogen production through acetic acid oxidative steam reforming as a bio-oil aqueous phase model compound. CeO2 was incorporated (5–30 wt.%) to improve the physico-chemical properties of the cataly... |
