Abstract: Disclosed is a core-shell structured nanocatalyst for hydrogen peroxide production. The core-shell structured nanocatalyst includes a core composed of spherical silica immobilized with noble metal nanoparticles and a mesoporous shell surrounding the core. The use of the nanocatalyst with a mesoporous shell for the production of hydrogen peroxide from hydrogen and oxygen ensures high hydrogen conversion and hydrogen peroxide production rate compared to the use of conventional nanoparticle catalysts with a microporous shell. Also disclosed is a method for hydrogen peroxide production using the nanocatalyst.

Abstract: The present process provides a method for synthesizing oxide-free copper nanometal dispersion in a free and reduced state using a solution phase synthesis process. A solution of an organic reducing agent containing at least two proximal nitrogen atoms is reacted with a separate solution containing a copper salt reformulated into a charge transfer complex. The reaction products are stabilized with Lewis bases and Lewis acids and optionally can be concentrated by removing a portion of the volatile low molecular weight solvent by either the use of a partial vacuum or by chemical extraction into another phase.

Abstract: Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.
