Catalytic Activities of Noble Metal Phosphides for Hydrogenation and Hydrodesulfurization Reactions

Catalytic Activities of Transition Metal Phosphides for NO Dissociation and Reduction With CO

Transition metal phosphides are a group of compounds with interesting chemical/physical properties and potential applications in various fields, such as electronics, magnetism, photonics, catalysis, and so on1–4. In particular, metal phosphides (e.g. MoP, Ni2P, WP, Fe2P and Co2P) have been used as catalysts and extensively studied for hydrotreating reactions5–8. Among these phosphides, MoP, Ni2...

Transition Metal Sulfide Catalysts for Petroleum Upgrading – Hydrodesulfurization Reactions

Inhibition of the Hydrogenation and Hydrodesulfurization Reactions by Nitrogen Compounds over NiMo/Al2O3

The inhibiting effect of nitrogen compounds on the hydrogenation of aromatic compounds and on the hydrodesulphurization (HDS) of dibenzothiophene (DBT) and 4,6-dimethyl dibenzothiophene (4,6 DMDBT), has been systematically investigated over a commercial NiMo hydrotreating catalyst. Amongst the different nitrogen compounds considered, interestingly ammonia was found to have the strongest inhibit...

Catalytic activities of noble metal atoms on WO3 (001): nitric oxide adsorption

Using first-principles density functional theory calculations within the generalized gradient approximation, we investigate the adsorption of NO molecule on a clean WO3(001) surface as well as on the noble metal atom (Cu, Ag, and Au)-deposited WO3(001) surfaces. We find that on a clean WO3 (001) surface, the NO molecule binds to the W atom with an adsorption energy (E ads) of -0.48 eV. On the C...
