Special Issue Information

Dear Colleagues,

As the guest editor, my goal is to coordinate and promote cutting-edge research in “Synthesis, Application and Structural Analysis of Composite Materials”. This Special Issue is aimed at disseminating original studies, critical reviews and experimental work that contribute to the advancement of knowledge in areas such as the fabrication of innovative materials with tailored properties, capable of responding to the specific demands of various industries, such as electronics, biomedicine and renewable energy, thus driving the development of more efficient, sustainable and advanced technologies.

The vision is to provide a robust academic platform to experts to share their innovative research and, in turn, facilitate interdisciplinary dialogue between authors and readers from around the world.

I invite researchers, academics and industry professionals to submit their manuscripts to contribute to the enrichment of this Special Issue, which highlights emerging topics and future challenges in Synthesis, Application and Structural Analysis of Composite Materials.

Surface and interface engineering play a crucial role in enhancing the CO2 methanation performance of heterogeneous catalysts. In this study, we present NiO-TiO2 nanoparticles modified with oxygen vacancy-rich Fe3O4 clusters, significantly improving CO2 methanation performance. The as-prepared catalyst (referred to as NiO@Fe3O4) achieves an impressive CH4 selectivity of 91.2% and a methane production yield of 6400.50 μmol/g at 573 K, an approximately 83% increase compared to unmodified NiO nanoparticles (3154.2 μmol/g). The results of physical characterizations and gas chromatography confirm that the outstanding activity and selectivity of the NiO@Fe3O4 catalyst arise from the synergistic interaction between its surface-active sites. Notably, the high concentration of oxygen vacancies within Fe3O4 enhances CO2 activation, while adjacent NiO sites efficiently promote H2 dissociation. These findings provide valuable insights into the rational design of heterogeneous catalysts, highlighting the advantages of Fe3O4 as an efficient promoter over conventional metal oxides for catalytic applications. Additionally, we envision that the obtained results will help to design transition metal-based industry viable catalysts for a diverse range of applications. Full article

Currently, the disposal of waste tires is considered one of the priority environmental and public health problems worldwide. Every year, more than 1.4 billion unused tires are placed in landfills. Population growth, economic development, and a strong demand for vehicle production in the automotive industry increase this problem. In Mexico, nearly 36 million unused tires are deposited in landfills or clandestine deposits, the vast majority being burned or accumulated in the open air. The lack of regulations in the handling, disposal, and recycling of tires creates a worrying panorama for environmental care and the problems that this entails. The objective of this work is to propose a viable alternative for the final disposal and recycling of waste tires through the implementation of a company for the manufacture of products based on recycled rubber in the state of Tamaulipas, Mexico, reducing environmental pollution by these wastes and generating sources of employment through a sustainable company. For this purpose, a study was carried out in Tamaulipas, Mexico, through surveys to determine the number of tires that can be obtained and determine the feasibility of the business; subsequently, a prediction was made using simulation software to design and estimate the expected production in the manufacture of parking bumpers using two scenarios with two and four workers. Likewise, specialized software was used to optimize waste tire collection routes from the different tire stores to the company’s location. The results show that with an optimal design of the tire collection routes, up to 483 tons of waste tires can be recovered per year, representing 10% of the total unused tires in Tamaulipas. Because it is an environmental and social problem, installing a company manufacturing products based on recycled rubber is feasible and has a high probability of success for the region studied. According to the simulation, employing four workers increases productivity and decreases manufacturing costs. Through the simulation, three tire collection routes were determined considering the total number of tire stores in the city where the company is located. Full article
