Pd nanoparticles were successfully encapsulated inside mesoporous silicalite-1 nanocrystals (Pd@mnc-S1) by a one-pot method. The as-synthesized Pd@mnc-S1 with excellent stability functioned as an active and reusable heterogeneous catalyst. The unique porosity and nanostructure of silicalite-1 crystals endowed the Pd@mnc-S1 material general shape-selectivity for various catalytic reactions, including selective hydrogenation, oxidation, and carbon-carbon coupling reactions.

Two-dimensional catalyst supports with mono-atomic transition metals stabilized in special surface pockets conceptually promise excellent catalytic activity. Similar heterogenized monoatomic metal-based catalysts usually suffer from poor stability in liquid-phase reaction system, whilst highly ligand-stabilized metal-centers are less accessible for reactions. We report a twodimensional mono-atomic Fe/N/C layered nanostructure (2D-FeNC), generated through the direct polycondensation of C,N-containing molecules and Fe salts. With a 2D structure similar to graphene, the ultrathin CN support act as a solid ligand, leaving the z-direction open at molecular scale. This approach significantly promotes reactivity and the mass transfer to the Fe centers, here exemplified by the selective oxidation of alcohols using molecular oxygen. The catalysts show also high mechanical and chemical stability for good to excellent reusability.

PurposeThe purpose of this paper is to investigate the effects of anthropomorphism and identify factors related to adopting voice shopping on smart speakers.Design/methodology/approachProgress in partial least squares structural equation modeling (PLS-SEM) approach is used to test the proposed research framework regarding anthropomorphism and user perceptions on voice shopping via smart speakers. Individuals' responses to questions about attitude and intention to use voice shopping via smart speakers were collected and analyzed.FindingsThe results showed that anthropomorphism had a positive influence on satisfaction, which, in turn, had a positive impact on intention to adopt voice shopping, and customers had positive opinions regarding smart speakers.Research limitations/implicationsThis study only reflects a younger perspective on smart speaker voice shopping. This study identified the characteristics of smart speakers that increase customers' intention to purchase, which can be used to formulate sales strategies and management guidelines.Practical implicationsThis research provided a new perspective to enable practitioners to promote smart speakers for voice shopping. Smart speaker manufacturers can utilize the findings of this research to improve the system design of smart speakers to further facilitate voice shopping.Originality/valueUnlike previous studies, which focused on product attributes of smart speakers or voice shopping experiences, this study provided a clear picture of how the anthropomorphic feature of smart speakers affects customers' intention to adopt voice shopping.
