【用于超级电容器的CoTe@rGO电极材料的一步水热合成】经济和社会的不断发展导致包括化石燃料在内的传统不可再生能源枯竭，同时也造成了人类生存环境的不断恶化。因此，开发新的绿色能源，以及新的储能设备已成为研究的重点。超级电容器作为一种新型储能器件，具有功率密度高、能量密度高、循环寿命长等诸多优点，填补了传统电容器和化学电池的空白。提高超级电容器性能的最重要方法之一是开发新型电极材料。由Fe、Co、Ni、S、Se、Te组成的各种过渡金属硫属化物及其复合材料由于其优异的比电容和可变价态已成为研究的重点方向。然而，对过渡金属碲化物的研究还远远不够。鉴于钴的可变价态和碲的优异金属丰度，结合这两种元素的化合物理论上具有良好的电化学性能。石墨烯添加到反应物中也被认为能够显着提高所得电极材料的性能。
天津大学肖谧教授课题组在本工作中采用一步水热法制备了用于超级电容器的CoTe@还原氧化石墨烯（CoTe@rGO）电极材料。并且与纯CoTe相比，CoTe@rGO在比电容、循环稳定性方面展现了良好的电化学性能。即使在20 A/g的高电流密度下，依旧能体现优异的倍率性能。此外，该课题组还以3 M KOH为电解质，CoTe@rGO电极为正极，活性炭为负极，组装了具有更宽电位窗和更高能量密度的非对称超级电容器（ASC）。详情请点击：https://t.cn/A6MJPWqv

【Trans Tianjin Univ特刊征稿】Call for papers: Fuel Cell
Background and Rationale：
A fuel cell is an efficient and clean energy conversion device that can directly generate electricity from a wide range of carbon-free fuels, such as hydrogen, ammonia, and metal. Fuel cells can also be combined with various renewable generation systems, and will play an important role in the decarbonization process to address the grand goal of carbon neutrality. Different types of fuel cells have diversified application scenarios, including transportation, distributed power generation (proton exchange membrane fuel cell, PEMFC, and anion exchange membrane fuel cell, AEMFC), cogeneration (solid oxide fuel cell, SOFC), micro power (microfluidic fuel cell, MFC), etc. In the last decade, the feasibility of fuel cell commercialization has been widely recognized, and its development is viewed as a key strategy for many governments. Technological advances and policy guidance cooperatively promote the accelerated maturation of fuel cells.
Scope：
The main objective of this Special Issue in the journal Transactions of Tianjin University is to provide a platform for presenting the latest advances in fuel cell technology. Topics of interest include, but are not limited to:
Advanced polymer electrolyte membrane (PEM) materialsfor proton and anion exchanges.
Highlyactive catalysis of oxygen reduction reactions and oxidation reactions for various fuels and their materials.
Artificial intelligence (AI) application in fuel cells.
Water and thermal management and optimal design of fuel cells.
Macro-,meso-, and micro-scopic simulation of fuel cells and fuel cell systems.
Durability test and improvement of fuel cells.
