摘要

Cover Feature说明了一种将二氧化碳排放转化为CH4的方法，方法是使用具有圆形通道设计的3d打印碳单体。在内部，用MgO堵塞碳孔隙后沉积NiO-CeO2纳米颗粒，以防止其嵌入碳质基质中。在左边，显示了起始试剂的来源。中间是MgO浸渍的整体体和活性相。最后，甲烷被生成并作为合成天然气输送到家庭。更多信息可以在I. Martínez-López， A. Bueno-López和同事的研究文章中找到（DOI: 10.1002/cctc.202401806）。

Cover Feature: Positive Effect of Carbon Monolith Porosity Sealing with MgO in the CO2 Hydrogenation to CH4 Using NiO-CeO2 Active Phase (ChemCatChem 7/2025)

The Cover Feature illustrates a method to convert CO₂ emissions into CH₄ by using a 3D-printed carbon monolith with a circular channel design. Inside, NiO-CeO₂ nanoparticles are deposited after blocking the carbon porosity with MgO to prevent their becoming embedded in the carbonaceous matrix. On the left, the origin of the starting reagents is shown. In the middle, the monolith impregnated with MgO and the active phase is displayed. Finally, CH₄ is generated and delivered to houses as synthetic natural gas. More information can be found in the Research Article by I. Martínez-López, A. Bueno-López and co-workers (DOI: 10.1002/cctc.202401806).

期刊介绍： With an impact factor of 4.495 (2018), ChemCatChem is one of the premier journals in the field of catalysis. The journal provides primary research papers and critical secondary information on heterogeneous, homogeneous and bio- and nanocatalysis. The journal is well placed to strengthen cross-communication within between these communities. Its authors and readers come from academia, the chemical industry, and government laboratories across the world. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies, and is supported by the German Catalysis Society.
