This work establishes general trends for modifying the properties of TMC surfaces with metal modifiers.
Surface and interfacial catalysis plays a vital role in chemical industries, electrochemistry and photochemical reactions. The challenges of. Guest editors Jinlong Gong and Xinhe Bao introduce the Fundamental Insights into Interfacial Catalysis issue of Chemical Society Reviews. Graphical abstract.
In this review, we highlight recent progress — in infrared reflection absorption spectroscopy IRRAS studies on oxide powders achieved by using different types of metal oxide single crystals as reference systems. This review describes the state-of-the-art of the molecular-level understanding of water adsorption, dissociation and clustering on model surfaces of metal oxides.
Interfaces between 2D material overlayers and solid surfaces provide confined spaces for chemical processes, which have stimulated new chemistry under a 2D cover. Metal oxides are abundant in nature and they are some of the most versatile materials for applications ranging from catalysis to novel electronics. It is our pleasure to present this Chemical Society Reviews themed issue which summarizes the recent advances in understanding chemical reactions on well-defined, frequently single crystalline surfaces at the molecular level.
This special issue also unravels mechanistic and kinetic aspects of important catalytic reactions that feature in industrial processes, fuel reforming, fuel cells, the hydrogen economy, and environmental catalysis. Another important area of inspiration is biocatalysis and enzymes, and the comparison of reactions at different catalysts metal surfaces, enzymes at different interfaces metal-gas, metal-liquid, enzyme-liquid.

Catalysis relies on the transfer of organic substrates into the aqueous catalyst phase; but the limited solubility of these substrates in water leads to reaction rates much lower than those for conventional homo-geneous catalysis.
Here we show that catalysis at the interface of a two-phase system can be enhanced by using a 'promoter ligand' which, although soluble in the organic phase, will bind to the organometallic catalyst and thus increase its concentration close to the interface in the aqueous phase. We demonstrate this approach for the hydroformylation of 1-octene using a rhodium-based catalyst. A rate enhancement by a factor of 10—50 is observed when we introduce the promoter ligand PPh 3 in the organic phase.
