I am tenure track assistant professor at the University of Twente (UT) since January 2021.
I am passionate about education and research in the fields of materials science and photo-/electro-catalysis. My group’s research bridges materials science at the nanoscale to heterogeneous catalysis for the sustainable production of fuels and chemicals. We combine physical vapor deposition and solid-state methods – to design model nanostructured catalysts - with in-situ characterization techniques to elucidate structure-performance relationships and investigate catalyst stability in photo- and electrocatalytic reactions.
I lead the Electro-Chemical Materials Science team (ECMS), which is hosted by the PhotoCatalytic Synthesis group (PCS) of Prof. G. Mul at the Faculty of Science and Technology of UT.
ACADEMIC EXPERIENCE & EDUCATION
- Tenure track assistant professor at Uni Twente, NL
- Postdoc in materials science at Uni Erlangen-Nuremberg, DE, Schmuki lab
- PhD in metal oxide photo-electrocatalysis at Uni Milano, IT, Selli lab
- Master in Chemistry, Uni Milano, IT
During my PhD at Uni Milan IT, I developed photocatalytic materials that drive chemical reactions powered by solar light. I focused on earth-abundant semiconductor materials, namely metal oxides, and investigated their synthesis by electrochemical anodization to produce one-dimensional nanostructures.
I joined Uni Erlangen-Nuremberg DE as postdoc, where I worked on solid-state dewetting, i.e., the heat induced transformation of metal films into arrangements of defined metal particles, to design model photocatalytic materials.
At Uni Twente, I am expanding further my work on dewetting in the fields of photo- and electrocatalysis. With my team, we aim at investigating controlled dewetting processes to develop nanostructured metal catalysts and electrodes for photo- or electrochemical conversion processes of environmental relevance (e.g., water splitting and hydrogen evolution).

Electro-Chemical Materials Science (ECMS) - Altomare research group
The research of my team focuses on materials science at the nanoscale and is diversified over four interlaced themes: solid-state dewetting, electro- and photo-catalysis, and X-ray spectroscopy. Besides, I also lead a responsible research and innovation project studying the societal impact of electrocatalytic technologies.
I. Team members and research lines
- Shreyas Harsha (PhD candidate, electrocatalysis) and Rakesh Sharma (Postdoc, electrocatalysis) team up to study the electrochemical performance of dewetted nanoparticles. They focus on the effect of catalyst structure, morphology and composition on the electrocatalytic performance of dewetted nanoparticles (e.g., Pt, Pd, Ni, or bimetallic systems such as PdCu, NiCu). Electrochemical processes of interest are water electrolysis, i.e., hydrogen and oxygen evolution reactions, selective hydrogenation of carbonyl compounds from bio-oil upgrade, and selective reduction of nitrates in waste water.
- Tursun Abudukade (PhD candidate, photocatalysis) and Marco Pinna (PhD, photocatalysis, guest from Uni Como, Italy) join forces to investigate the stability and dynamic behavior of earth-abundant metal co-catalysts, such as Ni and Cu nanoparticles, on metal oxide semiconductors for photocatalytic reactions of environmental relevance such as solar water splitting and hydrogen generation. For this, they adopt operando synchrotron techniques such as X-ray absorption/emission spectroscopy.
- Adam Vass (Postdoc, electrocatalysis) studies the electrochemical conversion of methane to valuable products (methanol, ethane, ethylene) developing a gas-phase electrolyzer based on earth-abundant anode materials (e.g., transition metal oxides such as W, Sn or Ti oxides). He explores mechanistic aspects of methane conversion by operando infrared spectroscopy.
- Senna Middelveld (Postdoc, responsible research and innovation) Electrochemical conversion processes are expected to contribute in the near future to a transition towards more sustainable ("green") chemicals produced from surplus renewable electricity from wind and solar energy. Senna studies possible socio-technical configurations and pathways related to the electrochemical conversion in the chemical industry, spanning from established processes (water electrolysis and hydrogen generation) to perspective applications (e.g., upgrade of bio-oil, synthesis of hydrogen peroxide, or water treatment). She focuses on assessing the environmental and societal implications of materials (electrocatalysts and electrode materials) and produced chemical compounds.

Dewetted materials for photo- & electro-catalysis
Solid-state dewetting, or simply dewetting, is based on the metastable nature of thin metal films, which when heated up to sufficiently high temperatures tend to agglomerate forming particles. This phenomenon occurs via surface diffusion of metal atoms due to the high surface-to-volume ratio of thin films.
Dewetting received large attention in the past for causing failure of micro- and nano-electronic components. Thus, it has been regarded as detrimental for technology advancement and has been widely investigated to understand mechanistic aspects and prevent its occurrence. Our research takes a different perspective: controlled dewetting opens for unique design concepts for functional metal nanoparticles.
Since metal particles are crucial towards a variety of technologies and applications, for example heterogeneous catalysis, my team studies controlled dewetting phenomena to produce supported metal nanoparticles with defined properties, e.g., size, composition, morphology and structure, for application in photo- or electro-catalysis.
