Synthesis of atomically designed carbon-based composite materials

Popis výsledku v původním jazyce

The synthesis of atomically designed carbon-based composite materials has attracted considerable interest due to their potential applications in a range of fields, including photocatalysis and energy conversion. Among these materials, graphitic carbon nitride (g-C3N4) is of particular interest due to its distinctive electronic structure and stability, which make it an ideal candidate for the development of advanced photocatalytic systems. The integration of g-C3N4 with other carbon materials and transition metal oxides (TMO) can result in the formation of composites with enhanced functionalities.This workpackage of the AtomDeC project is concerned with the strategic synthesis and surface modification of g-C3N4-based composites [1, 2]. The incorporation of transition metal oxides into the g-C3N4 matrix is intended to address the intrinsic limitations of pristine g-C3N4, including the rapid recombination of photogenerated charge carriers and the limited light absorption range. By carefully controlling the synthesis conditions, atomically precise interfaces between g-C3N4 and TMOs can be achieved, resulting in improved charge separation and extended light absorption capabilities.Surface modification techniques play a crucial role in tailoring the properties of these composites. The deposition of noble metals, such as silver nanoparticles (Ag NPs), has been the subject of considerable interest due to their enhanced electron storage capacity, lower cost, and non-toxicity [1-3].These modifications enhance the photocatalytic efficiency by promoting effective charge transfer and increasing the active sites available for catalytic reactions.The synergistic effect of combining g-C3N4 with various TMOs, such as TiO2, ZnO etc. leads to composites that exhibit superior performance in photocatalytic applications. These materials can efficiently harness solar energy for environmental remediation and hydrogen production, addressing key challenges in sustainable energy conversion.In conclusion, the atomically designed synthesis of carbon-based composites incorporating g-C3N4 and TMOs, coupled with precise surface modification strategies, holds great potential for advancing photocatalytic processes and energy conversion technologies. The enhanced photocatalytic activity, driven by improved charge separation and extended light absorption, underscores the significance of these composite materials in future energy applications.Acknowledgement:This work was financially supported by the Ministry of Education, Youth and Sports, Czech Republic (con-tract no. 8F21007) through the research project cooperation between the AtomDeC Consortium by funding received from the Visegrad group(V4)-Japan 2021 2nd Joint Call on “Advanced Materials”.References[1] M.
