Abstract
In this work, the synthesized geopolymer was prepared using metakaolin and alkali activator, and during the geopolymerization process, g-C3N4 and different contents of GO were added to the geopolymer, and GO-g-C3N4-GP was finally obtained. These samples can remove methylene blue (MB) utilizing the synergistic effect of adsorption and photocatalysis. 10% GO-g-C3N4-GP had the best removal rate of 93.28% within 30 min, under visible light. The results confirmed that geopolymers can provide a reusable carrier for g-C3N4, and the presence of GO can hinder the recombination of charges and promote the migration of photogenerated electrons, further improving the photocatalytic performance. 10% GO-g-C3N4-GP was also used to 3D print a scaffold by using the direct ink writing technology. To improve the efficiency of MB removal, 3D printed samples were treated with acid, and the sample of the 3D printed 10% GO-g-C3N4-GP acid treatment was also effective in removing MB and facilitates the recovery of the active material. This work can provide a simple way for synthesizing green materials for removing organic dyes.
期刊介绍:
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
