Summary

Scientists used UV light — both direct photolysis and titanium dioxide photocatalysis — to break down polystyrene, LDPE, and HDPE microplastics and capture the released hydrogen gas as a potential clean fuel. The dataset documents hydrogen yields and conditions across the different plastic types and treatment methods. This approach could offer a dual benefit: destroying plastic waste while generating renewable hydrogen energy.

Dataset description: This repository contains data that support the results of the study on UV-induced photolysis and photocatalysis using TiO₂ as approaches to hydrogen production from polystyrene, LDPE, and HDPE microplastics under UVC irradiation. Funding: This research was supported by the the European Union under the REFRESH – Research Excellence For REgion Sustainability and High-tech Industries (Project No. CZ.10.03.01/ 00/22_003/0000048) via the Operational Programme Just Transition, the OP JAK project "INOVO!!!", No. CZ.02.01.01/00/23_021/0008588 supported by the Ministry of Education, Youth and Sports and co-financed by the European Union and the authors also thank the Large Research Infrastructure ENREGAT (Project No. LM2023056).
