Activity Enhancement upon the Incorporation of Titanium: Au@Ti–SiO₂ Core–Shell Nanocatalysts for the CO Oxidation Reaction

ChemCatChem (2015)

Anandakumari C. Sunil Sekhar Kottavarithottil Ziyad Yogita Soni C. P. Vinod

Abstract The encapsulation of gold nanoparticles 8–12 nm in size within a porous Ti–SiO 2 shell to form a core–shell nanoarchitecture was investigated, and the catalytic activity of the resulting structure was probed. Detailed characterization of the synthesized materials shows that the core–shell morphology is lost beyond a certain amount of incorporated titanium, and results in normal gold‐supported Ti–SiO 2 . The material has a high surface area (913 m 2 g −1 ) and high porosity, both of which make it an excellent choice for catalytic applications. With the optimum amount of incorporated Ti, the core–shell catalyst shows excellent room‐temperature CO oxidation activity over several cycles with retention of its morphology at higher temperatures.

Single-Atom Alloy Formation via Reaction-Driven Catalyst Restructuring

Journal of the American Chemical Society (2024)

Georgios Giannakakis Yogita Soni Gregory L. Novotny Zhaoru Zha Nicole J. LiBretto

We demonstrate that single-atom alloy catalysts can be made by exposing physical mixtures of monometallic supported Cu and Pd catalysts to vinyl acetate (VA) synthesis reaction conditions. This reaction induces the formation of mobile clusters of metal diacetate species that drive extensive metal nanoparticle restructuring, leading to atomic dispersion of the precious metal, smaller nanoparticle sizes than the parent catalysts, and high activity and selectivity for both VA synthesis and ethanol dehydrogenation reactions. This approach is scalable and appears to be generalizable to other alloy catalysts.

A Convenient Route for Au@Ti–SiO₂ Nanocatalyst Synthesis and Its Application for Room Temperature CO Oxidation

The Journal of Physical Chemistry C (2017)

Yogita Soni Anumol Erumpukuthical Ashok Kumar Chandrani Nayak Francis Leonard Deepak C. P. Vinod

Small gold nanoparticles of size less than 5 nm encapsulated inside titanium modified silica shell have been reported. Here, a modified sol–gel method, which is a one-step process, produces Au@Ti–SiO2 nanocatalyst with a good control of titanium loading. With a titanium loading of 0.9 and 2.2 wt % in silica, unprecedented low temperature activity (full conversion) is observed for this catalyst for CO oxidation reaction compared to Au@SiO2 catalyst. A combination of optimum sized gold nanoparticles with a large amount of oxygen vacancies created due to Ti incorporation in silica matrix is considered to be the reason for this enhanced catalytic activity. The size of gold nanoparticles is maintained even after high temperature pretreatments, which show the benefit of encapsulation. The effect of the various pretreatments on the catalytic activity has also been reported.
