Artificial Humic Acids: Sustainable Materials against Climate Change

Adv Sci (Weinh). 2020 Jan 21;7(5):1902992. doi: 10.1002/advs.201902992. eCollection 2020 Mar.

Abstract

Humic acid, as a natural organic matter, is widely distributed in surface soil, oceans, rivers, and other ecological environments throughout the whole earth ecosystem. Humic acid provides abundant organic carbon and helps to maintain a hydrated, pH and redox buffered environment hosting the soil microbiome. Humic acid is however also a largely ignored polymer material full of exciting functional properties, and its scale is enormous. This perspective article discusses its synthesis and management as a tool to tackle parts of the climate crisis as well its use in technological applications, as made by chemical conversion of agricultural side products to artificial humic acids.

Keywords: CO2 remediation; humic acid; hydrothermal processes.
