Published: July 14, 2022

The global industrialization accelerates the use of fossil fuels and hence excessive emissions greenhouse gasses, especially carbon dioxide (CO2), which poses a serious threat to ecological environment. CO2 capture is considered as potential strategy reduce amount released into atmosphere. development adsorption materials that are both economically feasible effective most critical issue. Biochar promising candidate for among materials. It offers diverse range raw lower environmental impact than other adsorbent Even though pristine biochar could be employed directly capture, it generally exhibits poor performance. Therefore, needs modified in practical applications improve physicochemical properties such specific surface area, pore structure, functional groups. This paper summaries recent research advances biochar-based adsorbents adsorption. Pre-combustion technology post-combustion investigated. production influence process conditions on capacity described detail. mechanism also discussed, summarized physical chemical adsorption, respectively, well corresponding presentation some current methods physical/chemical modification biochar. Finally, future prospects proposed order provide guideline by Despite progress made more efforts needed produce with higher long-term stability large-scale capture.

Biochar, Journal Year: 2023, Volume and Issue: 5(1)

Published: April 23, 2023

Abstract Due to large specific surface area, abundant functional groups and low cost, biochar is widely used for pollutant removal. The adsorption performance of related synthesis parameters. But the influence factor numerous, traditional experimental enumeration powerless. In recent years, machine learning has been gradually employed biochar, but there no comprehensive review on whole process regulation adsorbents, covering optimization modeling. This article systematically summarized application in adsorbents from perspective all-round first time, including modeling adsorbents. Firstly, overview was introduced. Then, latest advances removal were summarized, prediction yield physicochemical properties, optimal synthetic conditions economic cost. And by reviewed, efficiency, revelation mechanism. General guidelines whole-process presented. Finally, existing problems future perspectives put forward. We hope that this can promote integration thus light up industrialization biochar. Graphical
