摘要:

硅藻是由具有獨特納米和微米形態(tài)的單細胞藻類產(chǎn)生的三維（3D）天然生物材料，具有眾多優(yōu)異的結(jié)構(gòu)。硅藻納米技術(shù)是近些年來出現(xiàn)的一個新的研究領(lǐng)域，它在生物學(xué)、傳感器、吸附、納米輸送、新能源等諸多領(lǐng)域上得到了研究及應(yīng)用。由于它特殊的多孔三維分層結(jié)構(gòu)，高比表面積，以及其他導(dǎo)體或半導(dǎo)體材料結(jié)合與轉(zhuǎn)換的能力，使得其在能量存儲、低成本的天然電極材料的研究上得到了廣泛應(yīng)用。根據(jù)近些年來國內(nèi)外在此材料上的研究現(xiàn)狀，展示了使用硅藻基復(fù)合材料在超級電容器、電池、太陽能電池等其他能源設(shè)備上能源應(yīng)用的情況。

Abstract:

Diatoms are three-dimensional (3D) natural biomaterials produced by unicellular algae with unique nano- and micro-morphologies, with numerous excellent structures. Diatom nanotechnology is a new research field emerging in recent years. It has been studied and applied in many fields such as biology, sensor, adsorption, nano-transport and new energy. Due to its special porous three-dimensional structure, high specific surface area and the ability of other conductors or semiconductor materials to combine and transform, it has been widely used in energy storage and low cost natural electrode materials. According to the research status of this material both at home and abroad in recent years, the application of diatom-based composites to energy applications in other energy equipment such as supercapacitors, batteries and solar cells is demonstrated.
