“…Wet impregnation modification facilitated the introduction of higher concentrations of metals, leading to the formation of metal oxides on the biochar surface and an improvement in the porous structure. Interestingly, this comparative study of the ecotoxicological characteristics of Zn-decorated biochar prepared by either pretreatment of the biomass or post-treatment of the biochar demonstrated that the final biochar Zn was found to be distinctly different [51]. For example, post-treatment led to biochar Zn with a higher content of polyaromatic hydrocarbons and thus more toxicity.…”

“…The order of wet impregnation and pyrolysis significantly influences the physicochemical properties of the biochar composites, such as the pore structure and the specific surface area. SEM analysis indicated that pre-treatment followed by pyrolysis induces the catalyzed carbonization of the biomass and the formation of pores and leads to a considerable surface area [51]. This contrasts with the post-treatment of the pyrolyzed samples, containing less unevenly distributed inorganic particles/larger crystal clusters and resulting in the blocking of pores and reductions in the specific surface area (Figure 4).…”

Due to ever-increasing global warming, the scientific community is concerned with finding immediate solutions to reduce or utilize carbon dioxide (CO2) and convert it in useful compounds. In this context, the reductive process of CO2 methanation has been well-investigated and found to be attractive due to its simplicity. However, it requires the development of highly active catalysts. In this mini-review, the focus is on biochar-immobilized nanocatalysts for CO2 methanation. We summarize the recent literature on the topic, reporting strategies for designing biochar with immobilized nanocatalysts and their performance in CO2 methanation. We review the thermochemical transformation of biomass into biochar and its decoration with CO2 methanation catalysts. We also tackle direct methods of obtaining biochar nanocatalysts, in one pot, from nanocatalyst precursor-impregnated biomass. We review the effect of the initial biomass nature, as well as the conditions that permit tuning the performances of the composite catalysts. Finally, we discuss the CO2 methanation performance and how it could be improved, keeping in mind low operation costs and sustainability.

“…Modified BC may potentially have negative effects on microorganisms in salt-affected soils. In the research of Marcinczyk et al (2023), the porosity of BC decreased, while the content of Zn and Cu increased, and it contained a greater concentration of dissolved organic carbon (DOC). Owing to these changes, the modified BC demonstrated an increased toxicity towards A. fischeri and D. manga.…”

“…For instance, Zn may adversely affect soil microorganisms. Marcinczyk et al (2023) discovered that BC modified with Zn after pyrolysis at 700°C had toxic effects on A. fischeri, reducing its luminescence by 50%. Modified BC may also aggravate the risk of soil salinization and Na + stress on plants.…”

The continuous growth of the world's population has led to an increased demand for food. Biochar (BC) contains valuable functional groups and nutrients, which have been demonstrated to enhance soil properties and boost crop yield. Nonetheless, unmodified BC exhibits significant alkalinity and a large salt concentration; thus, its efficacy in improving saline‐alkali soil remains a matter of contention. Therefore, scholars aim to address the aforementioned limitations by adapting BC. In this paper, a summary is given of the methods used to modify BC and the effects of modified BC on salt‐affected soil and saline‐alkali soil properties, including pH, nutrients and microbial activity. The effects and principles of different modifiers and modification methods on BC's physicochemical properties (porosity and functional group content and type, etc.) were revealed. Furthermore, the principle of soil improvement by modified BC varies depending on the modification method. Although modified BC can effectively enhance salt‐affected soil, its excessive application and improper selection of modifiers can aggravate Na+ toxicity or introduce other pollutants into salt‐affected soil. Therefore, using modified BC with care is imperative according to the actual situation. In this review, we provide a detailed introduction to the methods and principles of BC modification for saline‐alkali soil. Furthermore, we identify the shortcomings and future research directions in this field. These insights are valuable when choosing proper BC modification methods for salt‐affected soil.
