Research Themes

Unique composite materials

Designing new composites by combination of semiconducting MOFs, perovskites, metal oxides and gallium nitride materials for unprecedented material synergy, maximizing activity (STH efficiency/energy transfer) and long-term stability.

Non-precious metal co-catalysts

Exploration of MXenes as non-precious metal co-catalysts, replacing expensive Au, Pt, Pd or less sustainable Ni, Co materials, to improve charge separation and reduce electron-hole recombination.

Carbon textiles as highly conductive supports

Carbon textiles represent an outstanding choice from every perspective - technologically, economically, and sustainability - allowing scalable and sustainable solar-driven hydrogen production.

Phthalocyanines & Porphyrins as Dual Agents

First use of metalated and non-metalated phthalocyanines and porphyrins as both photosensitisers and MOF-ligands to enhance PEC H2 production

Design of new efficient tandem cells for hydrogen production

Development of robust, cost-effective tandem cell devices enabling overall water splitting (OWS) reactions.

Expanding the Photocathode Library

Broader investigation of semiconducting materials and co-catalysts to diversify and improve photocathodes, beyond the current reliance on precious-metals.

1st International Conference on EMPOWER Women in MOFs and Beyond
2025-11-09–14
Our group participated in the 1st International Conference on EMPOWER Women in MOFs and Beyond, held in November in Mexico, bringing together researchers working on metal–organic frameworks, porous materials, and related functional systems. The event focused on promoting the scientific achievements of women in the field, fostering mentoring, networking, and new international collaborations across academia and industry. As part of the program, our team contributed a poster entitled “Design strategies for water-stable perovskite-inspired materials in photoelectrocatalytic systems”, presenting our latest results on robust materials for solar-driven hydrogen technologies. More information about the conference is available at www.ewmb.com.mx.
The 1st International Conference on EMPOWER Women in MOFs and Beyond highlighted excellence in research on MOFs, porous solids, and advanced functional materials, with a strong emphasis on visibility and leadership of women scientists.

The scientific program covered topics from fundamental synthesis and characterization of MOFs and framework materials to their applications in energy conversion, gas storage, catalysis, and environmental remediation, creating a dynamic forum for exchanging ideas and building new projects. Our poster “Design strategies for water-stable perovskite-inspired materials in photoelectrocatalytic systems” showcased approaches to improving the stability and performance of perovskite-inspired semiconductors under aqueous operation, a key requirement for efficient photoelectrocatalytic hydrogen production and related reactions. Participation in this conference strengthens our international ties and supports the development of a more inclusive research community, where early-career scientists have the opportunity to present their work, gain feedback, and establish long-term collaborations.

Scientific outreach at IMDEA: Brain Wars and Science Week 2025
IMDEA scientific outreach activities 2025
2025-11-07 & 12
In November 2025, our team took part in two scientific outreach activities at IMDEA in Madrid, aimed at bringing cutting-edge energy research closer to students and the general public. On 7 November, researchers contributed to the VI edition of the scientific communication contest “Brain Wars: The Future Is in Your Hands”, an event that challenges young scientists to present their work in an engaging and accessible way. A few days later, on 12 November, we joined IMDEA Energía’s “Semana de la Ciencia y la Innovación”, visiting local schools to talk about sustainable energy, solar technologies, and hydrogen as a clean fuel. More information about these initiatives can be found at Brain Wars and Semana de la Ciencia.
The VI edition of “Brain Wars: The Future Is in Your Hands” invited young researchers to communicate their projects creatively, fostering debate, critical thinking, and public engagement with science.

During this competition, participants presented short, accessible talks about their work, showing how fundamental and applied research in areas such as materials, energy, and chemistry can address societal challenges and inspire future scientific careers. As part of the “Semana de la Ciencia y la Innovación 2025”, IMDEA Energía researchers visited secondary schools and vocational training centers, explaining how solar energy, green hydrogen, and other sustainable technologies contribute to a cleaner and more efficient energy system. Through interactive demonstrations, discussions, and classroom activities, these outreach actions aimed to spark curiosity about scientific research, encourage STEM vocations among young people, and raise awareness of the importance of innovation for a sustainable future.

Science as a passion: Interview with Pavla Eliášová in Svět ženy
Interview with Pavla Eliášová in Svět ženy
2026-01-24
The Czech women’s magazine Svět ženy has published an interview with Dr. Pavla Eliášová titled “Science as a passion”, highlighting her journey in chemistry and her dedication to clean energy research. In the article, she explains what motivated her to become a scientist, how she balances her professional and personal life, and why inspiring young people—especially girls—to pursue scientific careers matters to her. The interview also introduces her work on advanced materials for solar-driven water splitting and green hydrogen production within the international HYDRAGON project. Readers can access the magazine online at www.svetzeny.cz.
“Science is not only my job, it is my passion and a way to contribute to a cleaner future,” says Dr. Pavla Eliášová in the interview for Svět ženy.

In the feature, she talks about her research on new functional materials that use sunlight to split water into hydrogen and oxygen, a process known as water splitting. This green hydrogen can then serve as a clean fuel that produces only water when used, helping to reduce greenhouse gas emissions and support the transition to more sustainable energy systems. The interview also briefly presents the HYDRAGON (“From Light to Energy: Synergetic Multifunctional Materials Driving Photoelectrochemical Hydrogen Generation”) project, where international partners work together to design low-cost, efficient photoelectrochemical devices for hydrogen production from water, including non-traditional sources.
