Au/CeO2 metallic monolith catalysts: Influence of the metallic substrate
(World Gold Council, 2013)
Ceria-based gold catalysts were successfully deposited on ferritic stainless steel (Fecralloy) and aluminium monoliths. The prepared monolithic and reference powder catalysts were characterized by means of S BET, X-ray ...

Tailoring structured WGS catalysts: Impact of multilayered concept on the water surface interactions
(Elsevier, 2018)
A novel multilayer approach for designing structured WGS catalyst is employed in this study as a response to the lack of new strategies in the literature. The approach proposes the use of two successive layers with ...

Mesoporous carbon production by nanocasting technique using boehmite as a template
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
A series of mesoporous carbonaceous materials were synthesized by the nanocasting technique using boehmite as a template and glucose as a carbon precursor. After pyrolysis and template removal, the resulting material is a ...

Colombian metallurgical coke as catalysts support of the direct coal liquefaction
(Elsevier, 2019)
A Colombian metallurgical coke was modified in its surface chemistry and was used as support of iron sulfide catalysts for direct coal liquefaction. The modification was made by treatments with diluted oxygen and HNO3 at ...
