The Effect of Coking on Kinetics of HDS Reaction under Steady and Transient States [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2004
A study was made of the coking of a commercial fresh sulfide Ni-Mo/Al2O3 catalyst in a fixed-bed reactor. The catalyst was coked using different coke precursors in the gas oil under accelerated conditions at temperatures of 400 to 450°C to yield ...

Platinum‐Doped Carbon Nitride‐Loaded Poly(N‐Isopropylacrylamide) Hydrogel Thin Films for Green Hydrogen Production Systems: Morphological Study for Higher Efficiency

ChemSusChem, Volume 18, Issue 20, October 23, 2025.
Green hydrogen production mediated by hydrogel thin films prepared from poly(N‐isopropylacrylamide) and graphitic carbon nitride photocatalyst with platinum cocatalyst is investigated. The swelling behavior under humid conditions for various catalyst loadings is discussed, and internal morphology is probed by neutron scattering techniques.

Monolayer TiS2 Nanosheets on Au(111)–Structural Characterization and Effect of Edge Stability for Shape Control

Small, Volume 21, Issue 38, September 25, 2025.
Scanning tunneling microscopy (STM) and X‐ray photoelectron spectroscopy (XPS) have been used to obtain atomic‐level insights into 2D TiS2 nanosheets and [Au]Ti1S3 nuclei synthesized on Au(111) surfaces. Density functional theory (DFT) calculations showed that the chemical potential of S is the relevant shape descriptor and allows experimental steering
