Metal organic frameworks (MOFs) are considered as very promising candidates to build electrodes for electrochemical energy storage devices such as lithium ion batteries, fuel cells and supercapacitors, due to their diverse structure, adjustable aperture, large specific surface area and abundant active sites. Supercapacitor has been widely investigated in the past decades. Of critical importance in these devices is the electrode active materials, and this application has been intensively studied with the development of novel nanomaterials. In this review we summarize recent reports on MOFs as electrode materials for supercapacitors. Specifically, the synthesis of MOF materials for supercapacitor electrodes and their performance in electrochemical energy storage are discussed. We aim to include supercapacitor electrode materials related to MOFs, such as carbon, metal and composite materials. It is proposed that MOFs play an important role in the development of a new generation of supercapacitor electrode materials. Finally, we discuss the current challenges in the field of supercapacitors, with a view towards how to address these challenges with the future development of MOFs and their derivatives. 金属有机骨架材料具有结构多样、孔径可调、比表面积大及化学反应活性位点丰富等优点, 因此有望成为广泛应用于电化学储能 器件的电极材料, 如锂离子电池、燃料电池及超级电容器等. 近十年来金属有机骨架材料及其衍生物材料引起了广泛的研究与应用. 同 时, 金属有机骨架材料及其衍生的纳米材料作为电化学储能器件中的关键电极也受到了广泛的研究. 本文主要综述了近期金属有机骨架 材料及其衍生物在超级电容器中的研究进展, 讨论了金属有机骨架材料制备超级电容器电极材料的方法及其在电化学储能领域体现出的 优异性能及特殊性质, 同时也总结了近期金属有机骨架材料的衍生物如碳材料、金属材料及复合物在超级电容器中的研究进展, 结果说 明金属有机骨架材料在发展新一代超级电容器电极材料领域具有重要的作用. 最后讨论了金属有机骨架材料及其衍生物目前在超级电容 器领域存在的问题以及未来可能的发展方向.

Titanium (Ti) and its alloys are widely recognized as preferred materials for bone implants due to their superior mechanical properties. However, their natural surface bio-inertness can hinder effective tissue integration. To address this challenge, micro-arc oxidation (MAO) has emerged as an innovative electrochemical surface modification technique. Its benefits range from operational simplicity and cost-effectiveness to environmental compatibility and scalability. Furthermore, the distinctive MAO process yields a porous topography that bestows versatile functionalities for biological applications, encompassing osteogenesis, antibacterial, and anti-inflammatory properties. In this review, we undertake an examination of the underlying mechanism governing the MAO process, scrutinize the multifaceted influence of various factors on coating performance, conduct an extensive analysis of the development of diverse biological functionalities conferred by MAO coatings, and discuss the practical application of MAO in implants. Finally, we provide insights into the limitations and potential pathways for further development of this technology in the field of bone implantation.
