| 3 | Enhancing alkyne semi-hydrogenation through engineering metal-support interactions of Pd on oxides显示文摘Supported Pd catalysts show superior activities for olefin productions from alkynes through semi-hydrogenation reactions,but over-hydrogenation into alkanes highly decreases olefin selectivity.Using phenylacetylene semi-hydrogenation as a model reaction,here we explore the optimization approaches toward better Pd catalysts for alkyne semi-hydrogenation through investigating support effect and metal-support interactions.The results show that the states of Pd with supports can be tuned by varying oxide reducibility,loading ratios,and post-treatments.In our system,0.06 wt.%Pd on rutile-TiO_(2) nanorods shows the highest activity owing to the synergistic effects of single-atoms and clusters.Support reducibility can change the filling degrees of Pd 4d orbitals through varying interfacial bonding strengths,which further affect catalytic activity and selectivity. | Yuefeng Wu Xiaotong Lu Pengfei Cui Wenyu Jia Jun Zhou Yuan Wang Hussain Zahid Yuxin Wu Muhammad Umer Rafique Xiong Yin Baoshan Li Leyu Wang Guolei Xiang | 2024 | Nano Research2024，17，5： | 0 |
| 4 | Enhancing bioactivity and stability of polymer-based materialtissue interface through coupling multiscale interfacial interactions with atomic-thin TiO2 nanosheets显示文摘Stable and bioactive material-tissue interface(MTF)basically determines the clinical applications of biomaterials in wound healing,sustained drug release,and tissue engineering.Although many inorganic nanomaterials have been widely explored to enhance the stability and bioactivity of polymer-based biomaterials,most are still restricted by their stability and biocompatibility.Here we demonstrate the enhanced bioactivity and stability of polymer-matrix bio-composite through coupling multiscale material-tissue interfacial interactions with atomically thin TiO_(2)nanosheets.Resin modified with TiO_(2)nanosheets displays improved mechanical properties,hydrophilicity,and stability.Also,we confirm that this resin can effectively stimulate the adhesion,proliferation,and differentiation into osteogenic and odontogenic lineages of human dental pulp stem cells using in vitro cell-resin interface model.TiO_(2)nanosheets can also enhance the interaction between demineralized dentinal collagen and resin.Our results suggest an approach to effectively up-regulate the stability and bioactivity of MTFs by designing biocompatible materials at the sub-nanoscale. | Rongchen Xu Xiaodan Mu Zunhan Hu Chongzhi Jia Zhenyu Yang Zhongliang Yang Yiping Fan Xiaoyu Wang Yuefeng Wu Xiaotong Lu Jihua Chen Guolei Xiang Hongbo Li | 2023 | Nano Research2023，16，4： | 0 |
| 5 | Exploring electronic-level principles how size reduction enhances nanomaterial surface reactivity through experimental probing and mathematical modeling显示文摘Size reduction can generally enhance the surface reactivity of inorganic nanomaterials.The origin of this nano-effect has been ascribed to ultrasmall size,large specific surface area,or abundant defects,but the most intrinsic electronic-level principles are still not fully understood yet.By combining experimental explorations and mathematical modeling,herein we propose an electronic-level model to reveal the physicochemical nature of size-dependent nanomaterial surface reactivity.Experimentally,we reveal that competitive redistribution of surface atomic orbitals from extended energy band states into localized surface chemical bonds is the critical electronic process of surface chemical interactions,using H_(2)O_(2)-TiO_(2)chemisorption as a model reaction.Theoretically,we define a concept,orbital potential(G),to describe the electronic feature determining the tendency of orbital redistribution,and deduce a mathematical model to reveal how size modulates surface reactivity.We expose the dual roles of size reduction in enhancing nanomaterial surface reactivity-inversely correlating to orbital potential and amplifying the effects of other structural factors on surface reactivity. | Guolei Xiang Yang-Gang Wang | 2022 | Nano Research2022，15，4： | 0 |
