Summary: Biochar has shown great potential in environmental remediation due to its low cost, large specific surface area, porosity, and high conductivity. However, there is still a need to further explore the effects of biochar properties on catalytic performance and fill in the knowledge gaps in the reaction mechanisms of biochar-assisted advanced oxidation processes. Additionally, there is a lack of regeneration methods for biochar catalysts. Therefore, it is necessary to systematically review the latest research progress of biochar-assisted advanced oxidation processes in the treatment of organic pollutants in water.

Summary: S-defected MoS2 coupling with S,N-codoped porous biochar (MoS2/SN-BC) was prepared from chitosan via in-situ sulfuri-zation to enhance the adsorption-photocatalytic activity of biochar in wastewater purification. Compared with S-doped biochar (S-BC) and S,N-codoped biochar (SN-BC), MoS2/SN-BC exhibited better adsorption and photocatalytic activities for tetracycline hydrochloride (TCH). The adsorption-photocatalytic performance of 3-MoS2/SN-BC was slightly reduced after five cycles.

Summary: A novel composite of amorphous carbon and magnesium oxide nanofibers (C/MgO-F-600) was fabricated by an electrospinning method, possessing high performance, easy recycling, green characteristics, and low cost. The degradation efficiency of C/MgO-F-600 for methylene blue (MB) is 91.51%, which is approximately 1.9 times higher than that of MgO-600 nanosheets. The enhanced photocatalytic activity of C/MgO-F-600 is attributed to the moderate content of oxygen vacancies and 1D nanofiber structure, resulting in higher photocurrent density, photocatalytic activity, and the lowest bandgap and impedance. This work demonstrates the feasibility of improving practical applications of wide bandgap photocatalysts (MgO).

Summary: In order to enhance the adsorption activity of Ficus virens biochar for dye removal, S-doped biochar was co-modified by MgO and B2O3 via one-pot sulfurization. Mg-B/S-BC demonstrates higher adsorption capacity than S-doped biochar, MgO/biochar, and B2O3/biochar for rhodamine B. The adsorption capacity of optimal Mg-B/S-BC is 1195.25 mg g-1, and it decreases to 1142.97 mg g-1 after nine cycles.

Summary: A simple and green method was used to prepare MgO-loaded N-rich porous biochar (MgO/NBC) for CO2 capture. The microwave-induced marine biomass was used to construct this adsorbent without modifying and pore-forming agents. The adsorption mechanism of CO2 was explored by theoretical calculations, showing that the microwave heating promoted the development of graded porous structure and the loading of MgO, resulting in better CO2 capture performance. The cycling performance of MgO/NBC was also demonstrated to be good.
