Competitive Coordination Strategy to Finely Tune Pore Environment of Zirconium-Based Metal–Organic Frameworks

ACS Applied Materials & Interfaces (2017)

Ting He Bing Ni Xiaobin Xu Haoyi Li Haifeng Lin

Metal-organic frameworks (MOFs) are a class of crystalline porous materials with reticular architectures. Precisely tuning pore environment of MOFs has drawn tremendous attention but remains a great challenge. In this work, we demonstrate a competitive coordination approach to synthesize a series of zirconium-metalloporphyrinic MOFs through introducing H2O and monocarboxylic acid as modulating reagents, in which well-ordered mesoporous channels could be observed clearly under conventional transmission electron microscopy. Owing to plenty of unsaturated Lewis acid catalytic sites exposed in the visualized mesoporous channels, these structures exhibit outstanding catalytic activity and excellent stability in the chemical fixation of carbon dioxide to cyclic carbonates. The zirconium-based MOFs with ordered channel structures are expected to pave the way to expand the potential applications of MOFs.

Boron‐Doped Ti₃C₂T_x MXene for Effective and Durable High‐Current‐Density Ammonia Synthesis

Small (2024)

Xia Luo Yeyu Wu Huihui Hu Tianran Wei Baoshan Wu

Abstract Ammonia (NH 3 ) synthesis via the nitrate reduction reaction (NO 3 RR) offers a competitive strategy for nitrogen cycling and carbon neutrality; however, this is hindered by the poor NO 3 RR performance under high current density. Herein, it is shown that boron‐doped Ti 3 C 2 T x MXene nanosheets can highly efficiently catalyze the conversion of NO 3 RR‐to‐NH 3 at ambient conditions, showing a maximal NH 3 Faradic efficiency of 91% with a peak yield rate of 26.2 mgh −1 mg cat. −1 , and robust durability over ten consecutive cycles, all of them are comparable to the best‐reported results and exceed those of pristine Ti 3 C 2 T x MXene. More importantly, when tested in a flow cell, the designed catalyst delivers a current density of ‒1000 mA cm −2 at a low potential of ‒1.18 V versus the reversible hydrogen electrode and maintains a high NH 3 selectivity over a wide current density range. Besides, a Zn–nitrate battery with the catalyst as the cathode is assembled, which achieves a power density of 5.24 mW cm −2 and a yield rate of 1.15 mgh −1 mg cat. −1 . Theoretical simulations further demonstrate that the boron dopants can optimize the adsorption and activation of NO 3 RR intermediates, and reduce the potential‐determining step barrier, thus leading to an enhanced NH 3 selectivity.

Cation-Exchange Induced Precise Regulation of Single Copper Site Triggers Room-Temperature Oxidation of Benzene

Journal of the American Chemical Society (2020)

Huang Zhou Yafei Zhao Jie Gan Jie Xu Ying Wang

The controllable synthesis of stable single-metal site catalysts with an expected coordination environment for high catalytic activity and selectivity is still challenging. Here, we propose a cation-exchange strategy for precise production of an edge-rich sulfur (S) and nitrogen (N) dual-decorated single-metal (M) site catalysts (M = Cu, Pt, Pd, etc.) library. Our strategy relies on the anionic frameworks of sulfides and N-rich polymer shell to generate abundant S and N defects during high-temperature annealing, further facilitating the stabilization of exchanged metal species with atomic dispersion and excellent accessibility. This process was traced by in situ transmission electron microscopy, during which no metal aggregates were observed. Both experiments and theoretical results reveal the precisely obtained S, N dual-decorated Cu sites exhibit a high activity and low reaction energy barrier in catalytic hydroxylation of benzene at room temperature. These findings provide a route to controllably produce stable single-metal site catalysts and an engineering approach for regulating the central metal to improve catalytic performance.

Negative Pressure Pyrolysis Induced Highly Accessible Single Sites Dispersed on 3D Graphene Frameworks for Enhanced Oxygen Reduction

Angewandte Chemie International Edition (2020)

Huang Zhou Tong Yang Zongkui Kou Lei Shen Yafei Zhao

Abstract Herein, we report a negative pressure pyrolysis to access dense single metal sites (Co, Fe, Ni etc.) with high accessibility dispersed on three‐dimensional (3D) graphene frameworks (GFs), during which the differential pressure between inside and outside of metal–organic frameworks (MOFs) promotes the cleavage of the derived carbon layers and gradual expansion of mesopores. In situ transmission electron microscopy and Brunauer–Emmett–Teller tests reveal that the formed 3D GFs possess an enhanced mesoporosity and external surface area, which greatly favor the mass transport and utilization of metal sites. This contributes to an excellent oxygen reduction reaction (ORR) activity (half‐wave potential of 0.901 V vs. RHE). Theoretical calculations verify that selective carbon cleavage near Co centers can efficiently lower the overall ORR theoretical overpotential in comparison with intact atomic configuration.

Anion‐Tailored EDL Induced Triple‐Layer SEI on High‐Capacity Anodes Enabling Fast‐Charging and Durable Sodium‐Storage

Angewandte Chemie (2024)

Jun Luo Kaiwei Yang Jingjing Gai Xixue Zhang Chengbin Peng

Abstract High‐capacity electrodes face a great challenge of cycling stability due to particle fragmentation induced conductive network failure and accompanied by sustained electrolyte decomposition for repeatedly build solid electrolyte interphase (SEI). Herein, Se‐solubility induced Se x 2− as self‐adjustment electrolyte additive to regulate electric double layer (EDL) for constructing novel triple‐layer SEI (inner layer: Se; mediate layer: inorganic; outer layer: organic) on high‐capacity FeS 2 anode as an example for achieving stable and fast sodium storage. In detail, Se x 2− in situ generated at 1.30 V (vs. Na + /Na) and was preferentially adsorbed onto EDL of anode, then converted to Se 0 as inner layer of SEI. In addition, the Se x 2− causes anion‐enhanced Na + solvation structure could produce more inorganic (Se 0 , NaF) and less organic SEI components. The unique triple‐layer SEI with layer‐by‐layer dense structure alleviate the excessive electrolyte consumption with less gas evolution. As a result, the anode delivered long‐lifespan at 10 A g −1 (383.7 mAh g −1 , 6000 cycles, 93.1 %, 5 min/cycle). The Se‐induced triple‐layer SEI could be also be formed on high‐capacity SnS 2 anode. This work provides a novel SEI model by anion‐tailored EDL towards stable sodium‐storage of high‐capacity anode for fast‐charging.
