The adoption of green technology is very important to protect the environment and thus there is a need for improving the existing methods for the fabrication of carbon materials. As such, this work proposes to discuss, interrogate, and propose viable hydrothermal, solvothermal, and other advanced carbon materials synthesis methods. The synthesis approaches for advanced carbon materials to be interrogated will include the synthesis of carbon dots, carbon nanotubes, nitrogen/titania-doped carbons, graphene quantum dots, and their nanocomposites with solid/polymeric/metal oxide supports. This will be performed with a particular focus on microwave-assisted solvothermal and hydrothermal synthesis due to their favourable properties such as rapidity, low cost, and being green/environmentally friendly. These methods are regarded as important for the current and future synthesis and modification of advanced carbon materials for application in energy, gas separation, sensing, and water treatment. Simultaneously, the work will take cognisance of methods reducing the fabrication costs and environmental impact while enhancing the properties as a direct result of the synthesis methods. As a direct result, the expectation is to impart a significant contribution to the scientific body of work regarding the improvement of the said fabrication methods.
采用绿色技术对于保护环境非常重要，因此有必要改进现有的碳材料制备方法。因此，本工作建议讨论、审视并提出可行的水热法、溶剂热法及其他先进的碳材料合成方法。将要审视的先进碳材料的合成方法将包括碳点、碳纳米管、氮/二氧化钛掺杂碳、石墨烯量子点及其与固体/聚合物/金属氧化物载体的纳米复合材料的合成。由于微波辅助溶剂热法和水热法具有快速、低成本以及绿色/环保等有利特性，因此将特别关注这两种方法。这些方法被认为对于当前和未来先进碳材料的合成与改性以应用于能源、气体分离、传感和水处理至关重要。同时，这项工作将考虑在提高合成方法所带来的性能的同时降低制造成本和环境影响的方法。因此，期望对有关改进上述制备方法的科学工作做出重大贡献。
