The cover shows the structure of Co^x+–Co⁰ interfacial sites which promote propene hydroformylation. Compared with the surface of metallic Co (111), the Co^x+–Co⁰ interfacial sites work synergistically and lower the energy barrier of propene hydroformylation.

The Cover Feature shows the atomic structure of Cu₅Pd nanoalloys for the electroreduction of NO₃^- to NH₃. The H atoms adsorbed on the Pd sites prefer to transfer to adjacent nitrogen intermediates adsorbed on the Cu sites, thereby promoting the hydrogenation of intermediates and the formation of NH₃.

In this cover, a dynamic metal-ligand coordination mechanism has been unveiled towards CO₂ electroreduction. Triazole-modified Ag with dynamic and reversible interfacial structures reduced the activation barriers of both CO₂ protonation and H₂O activation via breaking the linear scaling relationship, boosting the catalytic activity for the electroreduction of CO₂ into CO.

The cover describes a dynamical molecular catalyst of Ag pyrazole (AgPz), which undergoes deprotonation to form H vacancy on pyrrolic N (AgPz-H_vac) during propylene electrooxidation. The dynamically reversible interconversion between AgPz and AgPz-H_vac facilitates both the dissociation of H₂O and transfer of *OH to propylene, thus achieving efficient electrooxidation of propylene into propylene glycol.

On the cover, the maze represents the complex reaction pathways of the CO₂ hydrogenation. Different colored lines indicate that CO₂ gets the corresponding product through different pathways. The monsters on the pathway to the product represent the key steps to be overcome during the reaction process.

A comparative study was made between lattice-doping and surface-adsorbed single atoms, which created distinct interfacial structures to interact with oxygen-evolving intermediates. This work reveals the essence of electronic and steric effects for optimizing the catalytic process.

Integrating electrochemical and biocatalytic components is difficult owing to incompatible rates and conditions. The cover describes a spatially decoupled system combining CO₂ electrolysis with yeast fermentation, which efficiently produces glucose or fatty acids from CO₂ and H₂O.

On the cover, the regulation of pore sizes for the microstructure of porous Cu shells enhanced the local confinement of reaction intermediates, facilitating C–C coupling and, thus, improving the selectivity for C₂₊ products over core-shell Ag@Cu catalysts towards CO₂ electroreduction.

The cover is an artist’s depiction of a novel molecular modification strategy presented for efficient CO₂ electroreduction by encapsulating palladium nanoparticles into metal?organic frameworks with 2,2′-bipyridine ligands. The catalysts achieve high CO faradaic efficiency over wide potential windows via optimizing the binding of key intermediates based on the electronic interaction between the palladium surface and 2,2′-bipyridine.

On the cover, the two hands represents the sites which adsorb oxygen atoms in CO₂. Such adsorption configuration benefits bending the linear CO₂ molecule. The halo surrounding the hands represents charge density gradients which can polarize non-polar CO₂ molecules.
