As part of the dissemination activities within the SOL-MAT-CLEAN project, doctoral researcher Sandra Romac presented research results at the 10th Faculty of Science PhD Student Symposium, held in Zagreb, Croatia, on 24 - 25 April 2026.

The poster presentation, titled “Engineering In₂O₃/BiVO₄ heterojunctions for enhanced visible-light degradation of contaminants of emerging concern”, focused on the development of heterojunction photocatalysts for improved visible-light-driven degradation of contaminants of emerging concern (CECs), particularly ciprofloxacin and PFOA. The research investigated the structural, optical, and photocatalytic properties of In₂O₃/BiVO₄ composites and their potential application in sustainable water treatment technologies.

The presented work was carried out in collaboration with Suresh Kumar Pandey, Hrvoje Kušić, Marin Kovačić, Ana Lončarić Božić, and Urška Lavrenčič Štangar.

As part of the dissemination activities within the SOL-MAT-CLEAN project, two scientific posters were presented at the 16^th Meeting of Young Chemical Engineers (SMLKI) by postdoctoral researcher Suresh Kumar Pandey, PhD and doctoral researcher Sandra Romac. The presented research focused on the development of solar-active photocatalytic materials for degradation of contaminants of emerging concern (CECs), particularly PFAS and pharmaceuticals.

Sandra Romac presented research on In₂O₃-based composites modified with carbon nanomaterials, including carbon quantum dots and reduced graphene oxide, for enhanced photocatalytic degradation of perfluorooctanoic acid (PFOA). The study investigated the influence of carbon-based modification on photocatalytic performance compared to pure In₂O₃.

Suresh Kumar Pandey presented work on a g-C₃N₄/In₂O₃ heterojunction photocatalyst with tailored band alignment for enhanced visible-light-driven degradation of contaminants. The study demonstrated improved charge separation and enhanced photocatalytic performance under visible-light irradiation.

The scientific quality of the presented work was additionally recognized through the 2nd Best Poster Award received by Suresh Kumar Pandey. Participation at SMLKI contributed to the dissemination and visibility of the SOL-MAT-CLEAN project within the scientific community.
