Generation of subnanometric platinum with high stability during transformation of a 2D zeolite into 3D

Abstract: Single metal atoms and metal clusters have attracted much attention thanks to their advantageous capabilities as heterogeneous catalysts. However, the generation of stable single atoms and clusters on a solid support is still challenging. Herein, we report a new strategy for the generation of single Pt atoms and Pt clusters with exceptionally high thermal stability, formed within purely siliceous MCM-22 during the growth of a two-dimensional zeolite into three dimensions. These subnanometric Pt species are stabilized by MCM-22, even after treatment in air up to 540 °C. Furthermore, these stable Pt species confined within internal framework cavities show size-selective catalysis for the hydrogenation of alkenes. High-temperature oxidation–reduction treatments result in the growth of encapsulated Pt species to small nanoparticles in the approximate size range of 1 to 2 nm. The stability and catalytic activity of encapsulated Pt species is also reflected in the dehydrogenation of propane to propylene. Encapsulation of single-atom and particulate gold within growing zeolite frameworks generates active catalysts with exceptionally high thermal stability.

Mobile Banking Adoption: Application of Diffusion of Innovation Theory

Abstract: Many banks in Saudi Arabia are starting to offer banking services through mobile phones. However, not many studies investigate the factors that may help the bankers to design mobile services, which are suitable for and adoptable by bank customers. This study fills this gap and examines a number of factors affecting the mobile banking adoption. Using Diffusion of Innovation as a baseline theory, data are obtained from 330 actual mobile banking users. It is found that relative advantage, compatibility, and observability have positive impact on adoption. Contrary to the findings in extant literature, trialability and complexity have no significant effect on adoption. Perceived risk has a negative impact on adoption. The findings of this study will have practical implications for banking industry in Saudi Arabia.
