Aufgrund des zunehmenden Energiebedarfs und wachsender Umweltprobleme erfahren die Produktion von Solarbrennstoffen durch photokatalytische Wasserspaltung und die CO 2 ‐Reduktion mithilfe von Photokatalysatoren beträchtliches Interesse. In den letzten Jahren haben zahlreiche Studien gezeigt, dass die Effizienz der Photokatalysatoren für die Produktion von Solarbrennstoffen deutlich gesteigert werden kann, wenn man Graphen verwendet, das eine besondere konjugierte 2D‐Struktur und spezielle elektronischen Eigenschaften besitzt. Dieser Aufsatz gibt einen Überblick über jüngste Fortschritte bei der Anwendung von Photokatalysatoren auf Graphenbasis für die Produktion von Solarbrennstoffen einschließlich der CO 2 ‐Reduktion zu Kohlenwasserstoffen und der H 2 ‐Erzeugung mittels Wasserspaltung. Die Grundlagen der Wasserspaltung und der CO 2 ‐Reduktion werden kurz dargestellt. Die für die Verbesserung der photokatalytischen Leistung relevanten Funktionen des Graphens werden diskutiert. Mit Blick auf bestehende Herausforderungen und Möglichkeiten auf diesem vielversprechenden Gebiet werden schließlich mögliche Perspektiven erörtert.

The advancement of efficient, cheap, and durable catalysts for oxygen reduction reaction (ORR) to substitute Pt/C in metal-air batteries is of paramount importance. However, traditional solvent-based methods fall short in terms of environmental benign and scalability. Herein, a solvent-free organic-inorganic self-assembly approach is explored to construct cobalt single atom and cobalt nanocluster decorated nitrogen-doped porous carbon spheres (Co-SA/NC@NCS). The solvent-free synthesis demonstrates an impressively high yield (282 g/L) and the resultant Co-SA/NC@NCS possesses a high N content (6.9 wt%). Density functional theory calculations disclose that the Co-SAs and Co-NCs are able to optimize the surface oxygen adsorption capability and enhance the conductivity of the NCS, thereby facilitating the ORR performance. The solvent-free synthesis is also feasible for the synthesis of other non-noble metal element (Fe, Ni, and Zn) decorated nitrogen-doped porous carbon spheres.

A Highly Stable and Non-Flammable Deep Eutectic Electrolyte for High-Performance Lithium Metal Batteries

Angewandte Chemie 2024年第43期136卷

Deep eutectic electrolytes (DEEs) are regarded as one of the next-generation electrolytes to promote the development of lithium metal batteries (LMBs) due to their unparalleled advantages compared to both liquid electrolytes and solid electrolytes. However, its application in LMBs is limited by electrode interface compatibility. Here, we introduce a novel solid dimethylmalononitrile (DMMN)-based DEE induced by N coordination to dissociate LiTFSI. We confirmed that the DMMN molecule can promote the dissociation of LiTFSI by the interaction between the N atom and Li + , and form the hydrogen bond with TFSI − anion, which can promote the dissociation of LiTFSI to form DEE. More importantly, due to the absence of active α-hydrogen, DMMN exhibits greatly enhanced reduction stability with Li metal, resulting in favorable electrode/electrolyte interface compatibility. Polymer electrolytes based on this DEE exhibit high ionic conductivity (0.67 mS cm −1 at 25 °C), high oxidation voltage (5.0 V vs. Li + /Li), favorable interfacial stability, and nonflammability. Li‖LFP and Li‖NCM811 full batteries utilizing this DEE polymer electrolyte exhibit excellent long-term cycling stability and excellent rate performance at high rates. Therefore, the new DMMN-based DEE overcomes the limitations of traditional electrolytes in electrode interface compatibility and opens new possibilities for improving the performance of LMBs.

Owing to their ubiquitous use by natural systems, Au fractal structures by electrodeposition have been included in the design of new functional materials , yet a need exists for studying probe factors that influence the nature of materials produced in this process. In this investigation, we observe the presence of HCl results in a uniform structure of individual Au clusters. Also, the increase of deposition potential causes a decreasing size of Au cluster by accelerating the deposition process . Finally, as the deposition time becomes longer, significant increases occur in areas, densities, and fractal dimensions of individual Au clusters on the biointerface.

Polyether ether ketone (PEEK) is one of the most commonly used materials in medical transplantation, and additive manufacturing is particularly useful for fabricating transplants as it can be used to form complex, customized parts. The main difficulty in forming PEEK parts using additive manufacturing is the high melting temperature of PEEK materials, which makes parts undergo a large temperature change during forming. This produces large internal stress, warpage, and delamination. Several structural design improvements in the regular fused deposition modeling (FDM) equipment are proposed in present work based on results from finite element simulations and experiments. The nozzle is augmented by a heat collector, which can significantly improve the uniformity of the temperature field during printing and increase the final strength of formed parts. Meanwhile, a two-degree-of-freedom platform is designed to reduce warpage of the forming plate caused by the high ambient temperature. XRD results show that the specimens formed using the improved equipment have higher crystallinity. Mechanical tests show that the warpage rate of a specimen can decrease from 20.4% to 5.0%, and the elastic modulus can increase by 20.1%.

Hollow nitrogen-doped carbon/ [email protected] 2 nanocomposite with structural and chemical dual-encapsulation for lithium-sulfur battery

Chemical Engineering Journal 2020年 381卷

作者： Hao Chen Wen-Da Dong Fan-Jie Xia Yun-Jing Zhang Min Yan Jian-Ping Song Wei Zou Yang Liu Zhi-Yi Hu Jing Liu Yu Li Hong-En Wang Li-Hua Chen Bao-Lian Su State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology 122 Luoshi Road 430070 Wuhan Hubei China Nanostructure Research Centre (NRC) Wuhan University of Technology 122 Luoshi Road 430070 Wuhan Hubei China Laboratory of Inorganic Materials Chemistry (CMI) University of Namur 61 rue de Bruxelles B-5000 Namur Belgium

Although lithium-sulfur (Li-S) batteries are one of the most promising energy storage systems, the low electrical conductivity of sulfur, the serious shuttle of the dissolved lithium polysulfides (LiPSs) and the large volume change during cycling greatly hinder the practical application of Li-S batteries. To overcome these issues, we report the in situ growing MnO 2 nanosheets on the hollow nitrogen-doped micropore-rich carbon (NMRC) to form NMRC/ [email protected] 2 nanocomposite with high sulfur content for advanced Li-S battery. The hollow nonpolar micropore-rich carbon nanospheres not only provide effectively structural confinement for active species but also accommodate the volume change during the charge–discharge process. The polar MnO 2 nanosheets and doped nitrogen present strong chemisorption for LiPSs. Consequently, the synergistic dual-encapsulation from structural confinement and chemisorption makes the NMRC/ [email protected] 2 nanocomposite has a theoretical sulfur loading of 72% and exhibit a high initial specific capacity of 1144 mAh·g −1 and a reversible capacity of 1023 mAh·g −1 after 200 cycles at 0.2 C. Even after 1000 cycles at 2.0 C, a capacity of 590 mAh·g −1 is maintained, among the best results for Li-S batteries. Our work reveals that the carefully design of sulfur-based composites with structural and chemical dual-encapsulation is promising to push forward the practical implementation of Li-S batteries.
