要旨

Au, @ZrO2 yolk–shell catalysts were found to exhibit a surprisingly high activity in CO oxidation even though the gold particle size is about 15 nm. A further enhancement of the activity has been achieved by simply doping these materials with small amounts of TiO2 during synthesis. A comparison of the standard Au, @ZrO2 yolk–shell catalysts with the novel TiO2-doped Au/Ti, @ZrO2 shows significant activity enhancement, even though small amounts of TiO2 are present.

Catalysis Science & Technology is committed to publishing research reporting high-quality, cutting-edge developments across the catalysis community at large. The journal places equal focus on publications from the heterogeneous, homogeneous, thermo-, electro-, photo-, organo- and biocatalysis communities. Works published in the journal feature a balanced mix of fundamental, technology-oriented, experimental, computational, digital and data-driven original research, thus appealing to catalysis practitioners in both academic and industrial environments. Original research articles published in the journal must demonstrate new catalytic discoveries and/or methodological advances that represent a significant advance on previously published work, from the molecular to the process scales. We welcome rigorous research in a wide range of timely or emerging applications related to the environment, health, energy and materials. Catalysis Science & Technology publishes Communications, Articles, Reviews and Perspectives. More details regarding manuscript types may be found in the Information for Authors section.
