Exploring the Adsorption Site Coordination as a Strategy to Tune Copper Catalysts for CO2 Electro-reduction

The electrochemical reduction of CO2 is a promising technology to reach a carbon-neutral economy. However, among other challenges, the design of active and selective catalysts still bottlenecks such advances. Herein,...

Asymmetric hydroamination with far fewer chiral species than copper centers achieved by tuning the structure of supramolecular helical catalysts

The incorporation of a few chiral monomers (the “sergeants”) in a backbone composed of a majority of achiral monomers (the “soldiers”) is a well-established strategy to control the handedness of...

Effect of Co, Cu, and Zn on FeAlK catalyst in CO2 hydrogenation to C5+ hydrocarbons

Direct CO2 hydrogenation to long-chain hydrocarbons can mitigate global warming by extensively replacing fossil fuels. However, designing a suitable catalyst with high catalytic activity and C5+ hydrocarbon selectivity continues to...

Modulation of the metal-support interaction plays a key role in many important chemical reactions. Here, by adjusting the reduction method of the catalyst and introducing oxygen vacancies in TiO2 to...

Facet-dependent activity of shape-controlled TiO2 supported Au nanoparticles for water-gas shift reaction†

The bifunctional role of noble metal/oxide interface in the activation of reactants is of vital importance in heterogeneous catalysis of water-gas shift (WGS) reaction. Herein, three types of shape-controlled TiO2...

Nonoxidative Coupling of Ethane with Gold loaded Photocatalysts

Direct and continuous conversion of ethane to yield n-butane and hydrogen at near room temperature (ca. 320 K) was examined with gold loaded gallium oxide and titanium dioxide photocatalysts without...

In-situ FTIR to unravel the bifunctional nature of aromatics hydrogenation synergy on zeolite / metal catalysts

Acid sites, in particular Brønsted sites, are often reported to enhance the catalytic performance of metal catalysts, like platinum, in hydrogenation. The significant boost in catalytic performance suggests a bifunctional...
