Mechanisms of Water Pollutant Degradation under Electric Discharge Generated in a Cavitating Flow

Clean Technologies
With the aim of developing an innovative water treatment approach for developing countries in the Global South, we have applied the method of treating a cavitating water stream with a plasma discharge under real conditions. To this end, we have optimised

Membrane‐aided simultaneous reaction–separation for liquid phase products

AIChE Journal, EarlyView.
Abstract Conventionally, reaction and separation are conducted as separate steps in liquid‐phase manufacturing, with products formed during reaction and subsequently separated from unreacted reagents, solvents, and byproducts. Integrating these steps into a simultaneous reaction–separation process can improve efficiency and reduce costs.

Adaptive Hydrogenation of Alkynes Using CO as a Molecular Trigger to Selectively Produce Alkanes or Z‐Alkenes

Angewandte Chemie, EarlyView.
One catalyst for two products: CO acts as a molecular trigger for adaptive alkyne hydrogenation using supported Pd nanoparticles. The catalyst reversibly switches between the formation of alkanes under H2 and Z‐alkenes under H2/CO for 37 structurally diverse alkynes.

Direct synthesis of propene oxide from propene, hydrogen and oxygen in a catalytic membrane reactor

, 2014
The direct gas-phase epoxidation of propene in a catalytic membrane reactor has been investigated. Powdered Au/Ti-SiO2 catalyst pressed into a disc was used as a membrane contactor, allowing different feeding of the reactants and providing resistance to ...
