ECOINNOCATALYSTS is a groundbreaking research project that aims to develop a more sustainable and environmentally friendly approach to surface modification of electrode materials for use as photo- and electrocatalysts for the hydrogen evolution reaction, HER.
The project is a collaboration between scientists from various disciplines, including chemistry, materials science, and renewable energy.
The use of deep eutectic solvents, DES as a green and inexpensive alternative to traditional solvents is at the core of this project. DES composed of natural and sustainable compounds, such as choline chloride and urea, are highly effective in dissolving and modifying various materials.
By utilizing DES, the project seeks to reduce the use of toxic and non-renewable solvents in the production of HER catalysts.
The ultimate goal of ECOINNOCATALYSTS is to develop a novel and efficient strategy for modifying electrode surfaces in DES, leading to enhanced catalytic activity for the HER.

While the HER is well-studied, the search for cost-effective, abundant, and durable electrode materials with comparable or superior catalytic activity to noble metals remains essential. Noble metals are limited by their cost, availability, durability, and susceptibility to catalyst poisoning. This research project focuses on three main objectives:
1. Investigating the electrooxidation processes of titanium and its alloys in DESs to produce highly organized nanostructured titanium dioxide layers with excellent photocatalytic activity for HER.
2. Studying the electrochemical deposition of nickel, cobalt, Ni-Co alloys, and their composites onto non-noble metal substrates and conductive carbon-based materials to create efficient electrocatalytic and photoelectrocatalytic coatings for HER.
3. Characterizing the electroless deposition of electrocatalysts based on cobalt, nickel, Ni-Co alloys, and platinum group metals onto various substrates to obtain highly efficient electrocatalysts for HER.
Each objective involves determining kinetic parameters, such as rate constants and activation energies, and understanding the underlying mechanisms. The catalytic activity of newly developed electrode materials will be evaluated by assessing parameters like hydrogen evolution overpotential and exchange current density in different aqueous solutions.

The project utilizes DESs known for their attractive physicochemical properties, stability, and biodegradability, ensuring an eco-friendly approach.

Methodologically, the project uses advanced techniques including electrochemical methods, spectral analysis (SEM, AFM, TEM, FTIR, Raman spectroscopy, EDS, XRD, and XPS), and chemical analysis (AAS, ICP, XRF) to comprehensively investigate and characterize electrode materials and coatings. Statistical methods will aid in data analysis and interpretation.

The research team embraces multi- and interdisciplinary approaches, open science principles, FAIR data access, and gender equality in research to ensure robust and collaborative scientific progress.

The project's expected outcomes include the development of theories describing the design and properties of innovative photo- and electrocatalysts, a diverse and cohesive research team, enhanced research capabilities, and increased visibility for young scientists. Ultimately, this project contributes to advancing sustainable hydrogen production and supports the EU's and SK's commitment to a green hydrogen economy.
