Abstract

Microalgae are one of the promising feedstocks for biorefinery, contributing significantly to net-zero emissions through carbon capture and utilization. However, the disposal of microalgal byproducts from the manufacturing process causes additional environmental pollution, thus, a new application strategy is required. In this study, the Tetraselmis suecica byproduct from the carotenoid extraction process was carbonized and converted into biochar. The converted biochar was proved to be nitrogen-doped biochar (NDB), up to 4.69%, with a specific surface area of 206.59 m2/g and was used as an electrode for a supercapacitor. The NDB electrode (NDB-E) in half-cell showed a maximum specific capacitance of 191 F/g. In a full-cell test, the NDB-E exhibited a high energy density of 7.396 Wh/kg and a high-power density of 18,100 W/kg, and maintained specific capacity of 95.5% after charge and discharge of 10,000 cycles. In conclusion, our study demonstrated that the carotenoid-extracted microalgal byproducts are a useful resource for the supercapacitor production. This approach is the first to convert T. suecica into active materials for supercapacitors.

从类胡萝卜素提取物 Tetraselmis suecica 中转化出掺有 N 的生物炭,并将其应用于生产超级电容器
微藻是生物精炼的一种前景广阔的原料,通过碳捕获和利用,可显著实现净零排放。然而,生产过程中微藻副产品的处理会造成额外的环境污染,因此需要一种新的应用策略。在这项研究中,类胡萝卜素提取过程中产生的 Tetraselmis suecica 副产品被碳化并转化为生物炭。经证实,转化后的生物炭为掺氮生物炭(NDB),含量高达 4.69%,比表面积为 206.59 m2/g,可用作超级电容器的电极。半电池中的 NDB 电极(NDB-E)显示出 191 F/g 的最大比电容。在全电池测试中,NDB-E 表现出 7.396 Wh/kg 的高能量密度和 18,100 W/kg 的高功率密度,并在充放电 10,000 次循环后保持了 95.5% 的比容量。总之,我们的研究表明,类胡萝卜素提取的微藻副产品是生产超级电容器的有用资源。这种方法首次将 T. suecica 转化为超级电容器的活性材料。

期刊介绍: The Journal of Environmental Sciences is an international journal started in 1989. The journal is devoted to publish original, peer-reviewed research papers on main aspects of environmental sciences, such as environmental chemistry, environmental biology, ecology, geosciences and environmental physics. Appropriate subjects include basic and applied research on atmospheric, terrestrial and aquatic environments, pollution control and abatement technology, conservation of natural resources, environmental health and toxicology. Announcements of international environmental science meetings and other recent information are also included.
