This cover was designed by Yuheng Wu and Yan Liu for an article published in Precis. Chem. (Volume 2, Issue 3, February 15, 2024). The cover illustrated thio ligand-modified Au nanoparticles as an extraordinary electrocatalyst to enhance the electroreduction of nitrate to ammonia due to the regulated electronic structure.

This cover was designed by Zhengtian Pu, Xinlong Ma, and Jie Zeng for an article published in Nano Lett. (Volume 24, Issue 3, December 5, 2023).  The cover shows the structure of Cox+–Co0 interfacial sites which promote propene hydroformylation. Compared with the surface of metallic Co (111), the Cox+–Co0 interfacial sites work synergistically and lower the energy barrier of propene hydroformylation.

This cover was designed by Zhiming Song and Zhigang Geng for an article published in ChemSusChem (Volume 16, Issue 22, March 27, 2023). 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.

This cover was designed by Xiangdong Kong, Jiankang Zhao, and Zhigang Geng for an article published in J. Am. Chem. Soc. (Volume 147, Issue 27, June 13, 2023). 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.

This cover was designed by Jingwen Ke, Mingfang Chi, Jiankang Zhao, and Zhigang Geng for an article published in J. Am. Chem. Soc. (Volume 145, Issue 16, March 21, 2023). The cover describes a dynamical molecular catalyst of Ag pyrazole (AgPz), which undergoes deprotonation to form H vacancy on pyrrolic N (AgPz-Hvac) during propylene electrooxidation. The dynamically reversible interconversion between AgPz and AgPz-Hvac facilitates both the dissociation of H2O and transfer of *OH to propylene, thus achieving efficient electrooxidation of propylene into propylene glycol.

This cover was designed by Hongliang Li and Menglin Wang for a viewpoint published in Acc. Mater. Res. (Volume 3, Issue 6, June 1, 2022). 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.

This cover was designed by Chen Feng, Zhirong Zhang, Shiming Zhou, and Jie Zeng for an article published in J. Am. Chem. Soc. (Volume 144, Issue 21, June 1, 2022). 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.

This cover was designed by Tingting Zheng, Menglu Zhang and Chuan Xia for an article published in Nature Catal. (Volume 5, Issue 5, May 25, 2022). 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.

This cover was designed by Yongzhi Zhong, Xiangdong Kong and Zhigang Geng for an article published in Nano Lett. (Volume 22, Issue 6, February 14, 2022). 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.

This cover was designed by Yongxiang Liang for an article published in Nano Lett. (Volume 21, issue 20, August 19, 2021). 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.
