China Petroleum processing & Petrochemical Technology 2024年第3期26卷 42-52页

作者： Chen Jie Xu Yuebing Qi Jian Liu Bing Liu Xiaohao Department of Chemical Engineering School of Chemical and Material EngineeringJiangnan UniversityWuxi 214122China State Key Laboratory of Biochemical Engineering Institute of Process EngineeringChinese Academy of SciencesBeijing 100190China

The selective removal of trace acetylene in ethylene feed gas is of great significance in the petrochemicalindustry;however, there are still challenges in designing and developing high-performance catalysts. Here, a MOFassistedencapsulation strategy was adopted for the precise synthesis of diatomic Pd2 sites on a ZnO support. When usedfor the acetylene semi-hydrogenation reaction, the dual-atom Pd2-ZnO catalyst exhibited improved catalytic performance,achieving complete conversion of acetylene at 125 °C with an 89% selectivity to ethene, as compared to Pd single-atom andnanoparticles. This enhancement was mainly attributed to the catalyst’s ability to dissociate H2 and facilitate the desorptionof intermediate C2H4. Moreover, the strong interaction between the support and the diatomic Pd sites was responsible for thecatalyst’s excellent stability during the long-term reaction.

Co-MOF-derived stalk-flower like NiCo-LDH homostructure towards boosting electrochemical energy storage

Progress in Natural Science:Materials International 2024年第6期34卷 1236-1248页

作者： Panpan Li Xiaoliang Wang Shaobin Yang Jian Qi College of Mining College of Materials Science and Engineering Geology and Mineral Engineering Special Materials Professional Technology Innovation Center of Liaoning Province Key Laboratory of Mineral High Value Conversion and Energy Storage Materials of Liaoning Province Liaoning Technical University Department of Architecture and Civil Engineering Lyuliang University State Key Laboratory of Biochemical Engineering Institute of Process Engineering Chinese Academy of Sciences

The rational design of the heterostructure of multi-component materials acts on electrochemical ***, the effect of structure and component alone on the performance is ignored. Homostructure can reflect the advantages of structural design more directly and fully tap the potential of the material itself. Herein, the homogeneous stereostructure with NiCo-LDH nanostalks（NiCo-LDHS） and NiCo-LDH nanoflowers（NiCo-LDHF）was synthesized through simultaneous Co-MOF in-situ etch and electrodeposition. NiCo-LDHSnot only preserves the shape of MOF rods, but also forms a firm adhesion to nickel foam. The coated NiCo-LDHFon NiCo-LDHS increases the loading of pseudocapacity material. As a result of the high capacity of Ni（OH）2, the high conductivity of Co（OH）2, as well as the stalk-flower stereostructure, the NiCo-LDHS-Felectrode demonstrates a specific capacity of 2058 F g-1(13994 mF cm-2) at 1 A g-1, along with an ultrahigh rate capability, retaining 73.9 % of its capacity at 20 A g-1. Moreover, the assembled NiCo-LDHS-F//AC hybrid supercapacitor（HSC） exhibits striking energy and power densities of 48.44 Wh·kg-1(0.78 m Wh·cm-2) and 800 W kg-1(12.8 mW cm-2), ***, after 10,000 consecutive charging and discharging cycles, the device maintains a capacity retention of85.36 %, demonstrating its good cycling stability. These findings prove the essentiality of designing homogeneous structure for the advancement of energy storage performance.
