Abstract
The conversion of byproduct fly ash into beneficial materials has garnered significant attention over the years. Due to its unique properties, fly ash is widely utilized to modify the surface of carbon materials, enhancing porosity, conductivity, surface area, lithium storage capacity, cycling stability, and providing additional redox activity. It is also employed in electrocatalytic reactions (e.g., HER and ORR), galvanization, electrocoagulation of heavy metal pollutants, and as a composite cement filler. Recent findings suggest fly ash-integrated materials and surfaces significantly improve early-age mechanical strength and delay deformation. However, there are only a few reports explaining this aspect. This review discusses the electrochemical and physicochemical properties of fly ash and its role as a surface-modifying substance on an industrial scale.
多年来，将副产品粉煤灰转化为有益材料的研究一直备受关注。粉煤灰具有独特的性质，因此被广泛用于改性碳材料的表面，从而提高孔隙率、导电性、表面积、锂存储容量、循环稳定性，并提供额外的氧化还原活性。粉煤灰还可用于电催化反应（如 HER 和 ORR）、电镀、重金属污染物电凝，以及用作复合水泥填料。最新研究结果表明，粉煤灰集成材料和表面可显著提高早期机械强度并延缓变形。然而，只有少数报告对这方面进行了解释。本综述讨论了粉煤灰的电化学和物理化学特性，以及粉煤灰在工业规模上作为表面改性物质的作用。
期刊介绍：
The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry.
The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces.
The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis.
The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
