DFT studies on platinum stepped surfaces have been carried out in order to understand the differences in the electrochemical behavior between the surfaces with (111) and (100) terraces. Thus, adsorption energies of different ...

[EN] To optimize nitrogen-doped graphitic materials as metal-free catalysts for the oxygen reduction reaction mechanisms have to be better understood. Here, the role played by pyridinic nitrogen-dopants in the chemisorption-based ...

[EN] The performance of many advanced catalytic systems depends not only on the size and composition but also on the specific shape of the metal nanoparticles (NPs) from which they are assembled. In turn, the shape of ...
