Designing catalysts to proceed with catalytic reactions along the desired reaction pathways, e.g., CO2 methanation, has received much attention but remains a huge challenge. This work reports one Ru1Ni single‐atom alloy (SAA) catalyst (Ru1Ni/SiO2) prepared via a galvanic replacement reaction between RuCl3 and Ni nanoparticles (NPs) derived from the reduction of Ni phyllosilicate (Ni‐ph). Ru1Ni/SiO...
Mesocrystals (MCs) with high‐index facets may have superior catalytic properties to those with low‐index facets and their nanocrystal counterparts. However, synthesizing such mesocrystal materials is still very challenging because of the metastability of MCs and energetic high‐index crystal facets. This work reports a successful solvothermal method followed by calcination for synthesizing copper oxide‐based...
Tuning the electronic structures of mesocrystals at the atomic level is an effective approach to obtaining unprecedented properties. Here, a lattice‐confined strategy to obtain isolated single‐site Sn atoms in CuO mesocrystals to improve catalytic performance is reported. The Sn/CuO mesocrystal composite (Sn/CuO MC) has ordered Sn–O–Cu atomic interfaces originated from the long‐range ordering of the...
