Identification of PdPt alloys for preferential C6 olefin hydrogenation over aromatic hydrocarbons through density functional theory and microkinetic modeling
Autor: Haowen Ma, Jiayi Wang, Xuecheng Zhan, Yuan Xie, Limin Sun, Xiaoli Hu, Haoxiang Xu, Daojian Cheng
Publikováno v: Chemical Communications. 59:6529-6532
Pd3Pt1 is identified with high selectivity (low aromatic depletion), while Pd1Pt1 and Pd1Pt3 are more active for olefin hydrogenation. The PdPt alloys present superior sulfur tolerance compared to Pd.

Isoprene selective hydrogenation using AgCu-promoted Pd nanoalloys
Autor: Jindong Sun, Haoxiang Xu, Haowen Ma, Xuecheng Zhan, Jiqin Zhu, Daojian Cheng
Publikováno v: Faraday discussions.
Alloying is an effective approach to improve the catalysis performance of Pd-based catalysts for the selective hydrogenation of diolefins towards monoolefines. Herein, PdAgCu ternary nanoalloy catalysts were synthesised by a stepwise impregnation met

Autor: Xuecheng Zhang, Guanghao Guo, Zixin Li, Wenchao Meng, Yuefei Zhang, Qing Ye, Jin Wang, Shibo He, Xinbao Zhao, Jiming Chen, Ze Zhang
Publikováno v: Communications Engineering, Vol 3, Iss 1, Pp 1-10 (2024)
Abstract Superalloy materials exhibit susceptibility to fracture failures stemming from the influence of thermomechanical factors. To comprehensively understand the fracture mechanisms, material properties, root causes of failure, and the subsequent
