Abstract

The front cover showcases Au single-atoms and clusters stabilized on nanoparticulate edge-faces-rich Mg-Al layered double hydroxides (LDHs), supported on SiO₂ or CeO₂. The catalysts demonstrate impressive activity for aerobic oxidation of alcohols and selective hydrogenation of 4-nitrostyrene. In-situ XAFS and HRTEM reveal the well-dispersed Au(0) single atoms with 1.0 wt% Au loading. The surface OH of LDH NPs effectively stabilize Au and enhances catalytic activity by basic sites of LDH. More details can be found in the Research Article by Tamao Ishida and co-workers (DOI: 10.1002/cplu.202400465).

封面：利用纳米颗粒Mg-Al层状双氢氧化物制备金单原子和簇催化剂及其催化性能（ChemPlusChem 3/2025）

封面展示了稳定在纳米颗粒边缘面上的Au单原子和团簇，富含Mg-Al层状双氢氧化物（LDHs），由SiO₂或CeO₂支撑。该催化剂在醇的有氧氧化和4-硝基苯乙烯的选择性加氢反应中表现出令人印象深刻的活性。原位XAFS和HRTEM显示了分散良好的Au(0)单原子，Au负载为1.0 wt%。LDH NPs的表面OH有效地稳定了Au，并通过LDH的碱性位点增强了催化活性。更多细节可以在Tamao Ishida及其同事的研究文章中找到（DOI: 10.1002/cplu.202400465）。

期刊介绍： ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies. Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
