1. INTRODUCTION In 1964, Khoobiar reported that WO3 is reduced by H2 to blue WO3− x
when it is in contact with a Pt catalyst. 1 The blue color appears because hydrogen atoms …

A variety of adsorbed intermediates have been extensively assigned during CO 2
hydrogenation on Pt/γ-Al 2 O 3. However, the surface sites where the surface species reside …

As-prepared materials tested for a catalytic reaction are usually only precatalysts that
become active and/or selective under specific conditions. During this initial formation phase …

The selective hydrogenation of fatty acids to fatty alcohols can be achieved under moderate
conditions (180° C, 30 bar H2) by simultaneously supporting copper and iron oxides on …

The hydrogen spillover phenomenon offers a great potential for enhanced performance in
heterogeneous catalysis involving hydrogenation. Despite this, the current applications of …

The understanding of reaction mechanism is the key to develop the highly efficient catalyst.
The introduction of Pt on SO 4 2−/ZrO 2 surface greatly improves its catalytic stability in n …

Abstract Fe, Co, Si-pillared montmorillonites with micro-and mesopores and high thermal
stability were prepared by directly introducing transition metal ions (Fe and Co) and …

Silica-supported Pt nanoparticles were prepared by intercalation of [Pt (NH3) 4] 2+ ions into
layered silicate Na-ilerite. This material, with a high amount of Pt (20 wt.%), was used as a …

Two magnetic catalysts were synthesized by a modification route and applied into the
naphthalene hydrogenation at 553 K. For this propose, Fe 2 O 3-TiO 2 support and Rh/Fe 2 …

Theoretical models do not predict significant hydrogen spillover from metal particles to the
surface of a nonconducting oxide in the absence of a high concentration of OH groups. This …
