Overview
Dr. Roldan is conducting research to better understand the surface processes that influence heterogeneous catalysis phenomena, which are closely related to environmental remediation and clean energy. To achieve this, his team is using various computational tools to simulate the physical and chemical properties of systems, as well as the reaction mechanisms. By utilizing micro-kinetic models, they can optimize catalyst structures and working conditions, improve yields, select the best catalyst, and control sintering effects. These crucial topics placed him as Catalysis Theme Leader in the Net Zero Innovation Institute at Cardiff University (https://www.cardiff.ac.uk/net-zero-innovation-institute/research).

Research
His work's primary interest is optimising catalytic processes on heterogeneous systems, extended surfaces or nanoparticles. Mainly, he is interested in the following:
- Capture and utilisation of CO2
- Renewable and clean energy
- Material design, including atomic control manufacturing.
- Sintering and coalescence of nanostructures
To understand these aspects, he evaluates the balance between kinetics and thermodynamics, relying on computational technologies to simulate the reactor conditions. These have led to reductions in development costs, shorter time-to-market, and the design and development of more efficient materials. Applying computer methodologies such as ab initio, quantum mechanics/molecular mechanics simulations, or polarisables continuum models provides easy control of the parameters affecting the processes, leading to an atomic-level understanding of the process.
