Abstract
The rapid degradation of the environment, which includes water pollution and soil depletion, presents significant challenges to global sustainability efforts. According to a United Nations report, approximately 2 billion people do not have access to safe drinking water associated with declining soil quality which threatens agricultural productivity. In order to tackle these pressing societal issues, it is essential to focus on creating adaptable materials for remediation and sustainable resource management. Concurrently, the scientific community is confronted with the task of harmonising the effectiveness, financial feasibility and ecological footprint of these technologies. Here, we review the preparation methods and applications of biochar composites with a focus on pyrolysis, co-precipitation and ball milling techniques. The study highlights biochar composites achieve removal rates exceeding 98% for toxic metals like Cr(VI) and Pb(II) and improve soil fertility through nutrient retention mechanisms. Biochar composites exhibit promising potential in the energy sector for enhancing supercapacitor and lithium-ion battery performance. Breakthroughs in microwave-assisted pyrolysis have led to the development of energy-efficient synthesis methods, while innovative co-precipitation techniques have been discovered for pollutant adsorption. However, despite these promising developments, the high preparation costs and material stability challenges have limited large-scale implementation. Our analysis provides a roadmap for future research on low-cost synthesis methods and long-term stability. Ultimately, biochar composites can play a pivotal role in environmental remediation, energy storage and sustainable agriculture.
期刊介绍:
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
