Fluxionality of Subnano Clusters Reshapes the Activity Volcano of Electrocatalysis

The Sabatier activity volcano provides intuitive guide for catalyst design, but also imposes fundamental limitations on the composition and maximal activity of catalysts. We show that the ORR activity volcano is shifted and reshaped by the potential-dependent fluxionality of subnano cluster catalysts. Fluxionality causes the typically under-binding...

Accelerating the Photocatalytic Atom Transfer Radical Addition Reaction Induced by Bi2O3 with Amines: Experiment and Computation

Boosting Bi photocatalysis. The photocatalytic ATRA reaction mediated by Bi2O3 can be accelerated through the addition of certain amines. The key role of the amines is to ensure a thermodynamic stabilization of the homogeneous bismuth-based photocatalytic active species, namely a BimBrn-solvato complex, to yield the stabilized BiBr3amine-based complex,...

On‐purpose Ethylene Production via CO2‐assisted Ethane Oxidative Dehydrogenation: Selectivity Control of Iron Oxide Catalysts

That's what we want: Ni/Fe molar ratio can be used as a catalyst descriptor, for the xFe/zNiMgZr system, that significantly affects the C−H bond scission, resulting in ethylene production and not the undesired pathway of C−C bond cleavage for syngas generation. Abstract The potential of on-purpose ethylene production, in parallel with CO2 conversion...

Solidified and Immobilized Heteropolyacids for the Valorization of Lignocellulose

The Front Cover shows the valorisation of lignocellulose to various value-added chemicals. Here hydrogenation and dehydrogenation reactions play a crucial role, which can be catalysed by acids. Heteropolyacids are especially promising because they possess an adaptable Brønsted acidity. Due to their good solubility in water and organic solvents, recycling...
