This cover was designed by Haibin Yin, Hongliang Li, and Jie Zeng for an article published in Nano Lett. (Volume 24, Issue 16, April 24, 2024). On the cover, the surface Pt-Ti alloyed layers on Pt particles supported on TiO₂ exhibit excellent activity in catalyzing the conversion of CH₄, CO, and O₂ into CH₃OH, HCHO, and HCOOH. This work reveals that CO promotes the dissociation of O₂ on the surface Pt-Ti alloyed layers, subsequently activating CH₄ to form oxygenates.

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 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.

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-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.

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.
