Growth and structure of supported metal catalyst particles

The applications of supported metal catalysts vary widely, from selective hydrogenation in the fine chemicals industry to the control of vehicle emissions. Yet many basic questions about the structure, activity, and durability of these catalysts remain unanswered. For example, there is still much uncertainty about the mechanism of metal particle growth, or sintering, which is a major cause of c...

Hydrothermal liquefaction of microalgae over transition metal supported TiO2 catalyst

Hydrothermal liquefaction (HTL) of microalgae Nannochloropsis (NAS) over various transition metal M/TiO2 (M = Fe, Co, Ni, Mo, and Mn) was investigated. Ni/TiO2 was the most effective catalyst to improve the yield and quality of biocrude and the liquefaction conversion. Ni/TiO2 was characterized by XRD, XRF, and XPS. The research of Effect of reaction temperature on HTL of NAS over Ni/TiO2 sugge...

Growth from behind: Intercalation-growth of two-dimensional FeO moiré structure underneath of metal-supported graphene

Growth of graphene by chemical vapor deposition on metal supports has become a promising approach for the large-scale synthesis of high quality graphene. Decoupling of the graphene from the metal has been achieved by either mechanical transfer or intercalation of elements/molecules in between the metal and graphene. Here we show that metal stabilized two-dimensional (2D)-oxide monolayers can be...

Surface study of supported metal particles by 129Xe NMR.

The surfaces of platinum clusters in the supercages of NaY zeolite have been studied by ' Xe NMR over the temperature range 80—293 K. The sensitivity of this weakly perturbing technique makes it possible to reveal the heterogeneity of the electronic structure of the particle surface. The temperature dependence of the ' Xe spin-lattice relaxation indicates that the surface sites with the highest...
