For past few years, biochar has gained a great deal of attention for its versatile utility in agricultural and environmental applications. The diverse functionality and environmental-friendly nature of biochar have motivated many researchers to delve into biochar researches and spurred rapid expansion of literature in recent years. Biochar can be produced from virtually all the biomass, but the properties of biochar are highly dependent upon the types of feedstock biomass and preparation methods. The overall performances of as-prepared biochar in treating soil and water contaminants is generally inferior to activated carbon due to its lower surface area and limited functionalities. This limitation has led to many follow-up studies that focused on improving material characteristics by imparting desired functionality. Such efforts have greatly advanced knowledge to produce better-performing engineered biochar with enhanced capability and versatility. To this end, this review was prepared to compile recent advancements in fabrication and application of engineered biochar, especially with respect to the influences of biomass feedstock on the properties of biochar and the utilization of industrial wastes in fabrication of engineered biochar.
在过去几年里，生物炭因其在农业和环境应用中的多种用途而备受关注。生物炭的多样功能和环境友好特性促使许多研究人员深入开展生物炭研究，并推动了近年来相关文献的迅速增加。几乎所有生物质都能生产生物炭，但其性质高度依赖于原料生物质的类型和制备方法。由于比表面积较低和功能有限，制备好的生物炭在处理土壤和水污染物方面的整体性能通常不如活性炭。这一局限性引发了许多后续研究，这些研究聚焦于通过赋予所需功能来改善材料特性。这些努力极大地推动了知识进步，以生产出性能更优、功能更强且用途更广的工程生物炭。为此，本综述旨在汇编工程生物炭制备和应用方面的最新进展，特别是生物质原料对生物炭性质的影响以及工业废物在工程生物炭制备中的利用。
