水热碳化（HTC）是一种重要的热化学技术，可以在相对温和的处理条件（180-260 °C和2-10 MPa）下将高水分废物转化为有价值的产品（称为水热炭）。随着近年来对HTC和水热炭的研究迅速增长，针对该研究的当前和未来方向的综述文章很少。因此，本文旨在综述氢焦的各种新兴应用，例如，从固体燃料到土壤改良剂，从电子存储到储氢，从染料吸附、毒素吸附、重金属吸附到养分回收，从碳捕获到碳封存等，本文进一步介绍了水热炭的各种应用机理，以及如何通过对水热炭进行化学改性来提高其应用。最后，提出了新的观点和适当的建议，以进一步揭示潜在的应用和改进，通过水热炭及其改性版本。
Hydrothermal carbonization (HTC) is a prominent thermochemical technology that can convert high-moisture waste into a valuable product (called hydrochar) at a relatively mild treatment condition (180–260 °C and 2–10 MPa). With rapidly growing research on HTC and hydrochar in recent years, review articles addressing the current and future direction of this research are scarce. Hence, this article aims to review various emerging applications of hydrochars, e.g., from solid fuel to soil amendment, from electron storage to hydrogen storage, from dye adsorption, toxin adsorption, heavy metal adsorption to nutrient recovery, and from carbon capture to carbon sequestration, etc. This article further provides an insight in the hydrochar’s working mechanism for various applications and how the applications can be improved through chemical modification of the hydrochar. Finally, new perspectives with appropriate recommendations have been made to further unveil potential applications and its improvement through hydrochar and its modified version.
