**Preface to "Contemporary Solutions for Advanced Catalytic Materials with a High Impact on Society"**

"Contemporary solution for advanced materials with high impact on society"is a Special Issue dedicated to a workshop with a similar name (with the acronym CoSolMat) organized on the 11th–15th of October 2021 within the GREENCAM project (project no. 18-COP-0041, October 2019–September 2022, project partners University of Bucharest (UB, Bucharest, Romania), and Norwegian University of Science and Technology (NTNU, Trondheim, Norway)).

The GREENCAM project proposes an alliance between Green Chemistry and Advanced Materials in response to the contemporary issues related to the environmental pollution and eco-friendly industry, which emerged from the general concept of environmental preservation. In this way, GREENCAM offers a proper condition for the development of an extensive study in the area of advanced (e.g. nano-) materials with a critical awareness of the theoretical and practical aspects related to the modern concepts of green (nano)synthesis. GREENCAM advocates for the extensive application of the principles of green chemistry in chemical synthesis, especially for the preparation of these advanced materials as a promising perspective for an eco-friendly industry.

Based on the continuous advancements in the area of advanced materials and, as a consequence, the new challenges to be faced, a focus on this matter is highly desirable. UB, represented by Prof. Simona M. Coman and Assoc. Prof. Madalina Tudorache in collaboration with the NTNU represented by Assoc. Prof. Elisabeth Jacobsen launched the idea for collecting valuable publications dedicated to contemporary solutions for issues related to the preparation/characterization and applications of the advanced materials with a high impact on society. The main aim of this Special Issue is to highlight novel developed strategies designed for promoting Green Advanced Materials (GAM), i.e., new concepts and strategies for designing GAMs together with their most important application for improving the health and security of our present-day society. Teachers and researchers from academic and industrial areas with expertise in the GAMs field have offered their contributions. Furthermore, young researchers are well represented, also demonstrating their interests in this research direction. Therefore, this Special Issue has collected original topics, most of which were shared during the CoSolMat workshop, providing new insights into the GAMs field.

We conclude by hoping that this Special Issue will act in the future as a manifesto for the mandatory implementation of GAMs and Green Chemistry in order to ensure the industrial practices required for a healthy and secure society.
