Antonio Alberto Zaldívar-CadenaCristina SiligardiErika Iveth Cedillo-GonzálezMicroplastics (MPs), which are small plastic debris of ≤5 mm size, are polluting the oceans with negative consequences for their biota. In this work, visible-light photocatalysis of high-density polyethylene (HDPE) and low-density polyethylene (LDPE) MPs in aqueous medium using a mesoporous N–TiO2 coating is proposed as an alternative for fighting MP pollution. Spherical primary HDPE MPs were extracted from commercially available facial scrubs, while film-shaped secondary LDPE MPs were obtained from a plastic bag. For each plastic, two different sizes were tested. Degradation was measured by mass-loss and carbonyl-index (CI) calculation. The results obtained reveal that the photocatalytic degradation of HDPE and LDPE MPs using an N–TiO2 coating was affected by the size and shape of the MPs. Smaller MPs led to higher degradation, while film-shaped MPs led to lower degradation that was related to a poorly illuminated and oxygenated reaction medium. These results set the basis for further investigation on the on the design of more effective photocatalytic-reaction systems for decreasing MP inputs to the environment.

Microplastics (MPs) are distributed in a wide range of aquatic and terrestrial ecosystems throughout the planet. They are known to adsorb hazardous substances and can transfer them across the trophic web. To eliminate MPs pollution in an environmentally friendly process, we propose using a photocatalytic process that can easily be implemented in wastewater treatment plants (WWTPs). As photocatalysis involves the formation of reactive species such as holes (h+), electrons (e−), hydroxyl (OH●), and superoxide ion (O2●−) radicals, it is imperative to determine the role of those species in the degradation process to design an effective photocatalytic system. However, for MPs, this information is limited in the literature. Therefore, we present such reactive species’ role in the degradation of high-density polyethylene (HDPE) MPs using C,N-TiO2. Tert-butanol, isopropyl alcohol (IPA), Tiron, and Cu(NO3)2 were confirmed as adequate OH●, h+, O2●− and e− scavengers. These results revealed for the first time that the formation of free OH● through the pathways involving the photogenerated e− plays an essential role in the MPs’ degradation. Furthermore, the degradation behaviors observed when h+ and O2●− were removed from the reaction system suggest that these species can also perform the initiating step of degradation.
About Me
Dr. Erika Iveth Cedillo-González is a materials scientist specializing in the development of sustainable materials and processes for environmental remediation, with a particular focus on addressing microplastic pollution through photocatalytic degradation using semiconductor-based technologies. She obtained her B.Sc. and M.Sc. degrees from the Universidad Autónoma de Nuevo León (UANL), Mexico, and earned her Ph.D. from the University of Modena and Reggio Emilia (UNIMORE), Italy.
From 2016 to 2020, Dr. Cedillo-González served as an Associate Professor at UANL’s School of Chemistry, where she led research projects funded by CONACYT and SEP. She continued her academic career at UNIMORE, holding postdoctoral and associate researcher positions between 2021 and 2024.
She is currently establishing Pelucco R&D, an independent initiative aimed at developing scientific, technological, and educational strategies to combat plastic pollution. In parallel, she is actively involved in science communication and co-authored the illustrated children’s book "Pelucco, A Microplastic’s Journey", which introduces young audiences to the environmental challenges posed by plastic waste.
Her work has been recognized through multiple fellowships and awards, reflecting her strong commitment to environmental sustainability, scientific innovation, and public engagement.
