Department of Chemical and Metallurgical Engineering

Catalysis Research Group

The Catalysis group, lead by Prof. Puurunen, develops new types of solid heterogeneous catalysts and evaluates their performance, aiming for fundamental understanding and structure-activity relationships.
Catalysis Group picture

Focus areas:

  1. Sustainable catalytic processes from renewable resources

  2. Preparation of solid heterogeneous catalysts e.g. by atomic layer deposition

  3. Characterization of solid heterogeneous catalysts

Catalysts are at the core of chemical industry and are expected to enable a sustainable biobased economy of the future. Catalysts are made self by conventional methods such as impregnation and also by advanced methods such as atomic layer deposition (ALD). Catalysts are characterized for example by adsorption methods (chemisorption, physisorption, temperature-programmed methods), in situ spectroscopy with probe molecules (IR) and activity measurements, also in high-pressure reactors.

The Catalysis group, lead by Prof. Puurunen and founded in 2017, develops new types of solid heterogeneous catalysts and evaluates their performance, aiming for fundamental understanding and structure-activity relationships.

As of October 2020, the group’s project base is formed by the HDN cat project (Neste) for catalytic hydrodenitrogenation, the COOLCAT project for carbon dioxide activation to valuable chemicals (Academy of Finland, introduction in Youtube) and the ALDI project related to atomic layer deposition development (Academy of Finland).

Notes on our research group:

The CHEM-E1130 Catalysis course is among our core teaching responsibilities.

The group aims for a healthy, constructively critical research environment that supports the personal development & well-being of all members. The group strives towards more openness in science and teaching.

To learn more of the activities of the group and life at Aalto University, please have a look at our Twitter and Instagram accounts, the recent publications, and the group leader’s blog Catalysis Professor’s Open. Evolving group presentation can be found in this link
