Multicomponent Graphene Based Catalysts for Guaiacol Upgrading in Hydrothermal Conditions: Exploring "H2-free" Alternatives for Bio-compounds Hydrodeoxygenation
(Elsevier, 2023)
Catalytic hydrodeoxygenation (HDO) is a critical technique for upgrading biomass derivatives to deoxygenated fuels or other high-value compounds. Phenol, guaiacol, anisole, p-cresol, m-cresol and vanillin are all monomeric ...

In-situ HDO of guaiacol over nitrogen-doped activated carbon supported nickel nanoparticles
(Elsevier, 2021)
In-situ hydrodeoxygenation of guaiacol over Ni-based nitrogen-doped activated carbon supported catalysts is presented in this paper as an economically viable route for bio-resources upgrading. The overriding concept of ...

Ni-CeO2/C Catalysts with Enhanced OSC for the WGS Reaction
(MDPI AG, 2015)
In this work, the WGS performance of a conventional Ni/CeO2 bulk catalyst is compared to that of a carbon-supported Ni-CeO2 catalyst. The carbon-supported sample resulted to be much more active than the bulk one. The higher ...

K-Promoted Ni-Based Catalysts for Gas-Phase CO2 Conversion: Catalysts Design and Process Modelling Validation
(Frontiers Media, 2021)
The exponential growth of greenhouse gas emissions and their associated climate change problems have motivated the development of strategies to reduce CO2 levels via CO2 capture and conversion. Reverse water gas shift ...

Ni-Phosphide catalysts as versatile systems for gas-phase CO2 conversion: Impact of the support and evidences of structure-sensitivity
(Elsevier, 2022)
We report for the first time the support dependent activity and selectivity of Ni-rich nickel phosphide catalysts for CO2 hydrogenation. New catalysts for CO2 hydrogenation are needed to commercialise the reverse water–gas ...

MIL-100(Fe)-Derived Catalysts for CO2 Conversion Via Low- and High-Temperature Reverse Water-gas Shift Reaction
(Elsevier, 2023)
Fe-derived catalysts were synthesized by the pyrolysis of MIL-100 (Fe) metal-organic framework (MOF) and evaluated in the reverse water-gas shift (RWGS) reaction. The addition of Rh as a dopant by in-situ incorporation ...
