Abstract
- Due to ever-increasing global warming, the scientific community is concerned with finding immediate solutions to reduce or utilize carbon dioxide (CO<subscript>2</subscript>) and convert it in useful compounds. In this context, the reductive process of CO<subscript>2</subscript> 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 CO<subscript>2</subscript> methanation. We summarize the recent literature on the topic, reporting strategies for designing biochar with immobilized nanocatalysts and their performance in CO<subscript>2</subscript> methanation. We review the thermochemical transformation of biomass into biochar and its decoration with CO<subscript>2</subscript> 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 CO<subscript>2</subscript> methanation performance and how it could be improved, keeping in mind low operation costs and sustainability. [ABSTRACT FROM AUTHOR]
