摘要

在本期《化学催化》（Chem Catalysis）杂志上，Zhu 及其合作者报告了通过 H2 还原和 CO2 加氢，在 Ni 纳米粒子和 BaCO3 之间构建了一种新型强金属-支撑相互作用。BaCO3 在镍纳米粒子上的迁移导致多孔覆盖层的形成，这不仅稳定了镍纳米粒子以防止烧结，还形成了丰富的 Ni-BaCO3 界面以富集 CO2，从而促进 CO2 加氢制甲烷。

Strong metal-support interaction between Ni and BaCO3 boosts CO2 hydrogenation

In the current issue of Chem Catalysis, Zhu and co-workers report the construction of a neotype strong metal-support interaction between Ni nanoparticle and BaCO₃ via H₂ reduction and CO₂ hydrogenation. The migration of BaCO₃ onto Ni nanoparticles leads to the formation of porous overlayers, which not only stabilized the Ni nanoparticles against sintering but also formed abundant Ni-BaCO₃ interfaces for CO₂ enrichment, thereby enhancing CO₂ hydrogenation to methane.
