Nice work of Campinas Electrochemistry Group - PSF in collaboration with Angel Cuesta.
Long story short.
-We got inspired by this nice paper by Markovic and col: https://www.nature.com/articles/nchem.330
- We got several microscopic insights by performing FTIR in situ in the ATR mode.
- Among other findings, we got a rational and logical explanation for the cation-induced differences in activities in the voltammetric profiles for several alcohols and polyols.

The activity of Pt for the electro-oxidation of several organic molecules changes with the cation of the electrolyte. It has been proposed that the underlying reason behind that effect is the so-called noncovalent interactions between the hydrated cations and adsorbed OH (OHad). However, there is a....

Below is the link to the outcome of a nice collaboration with the group of Linsey Seitz from Northwestern University. A great effort of Jane Edgington, Rafael Vicente (from Campinas Electrochemistry Group - PSF) and col.

This study explores the dynamic behavior of Ln₃IrO₇ (Ln = Pr, Nd, Sm, Eu) catalysts for OER, highlighting how tunable Ir-rich surfaces enhance performance in proton exchange membrane water electrolysis (green hydrogen production).

This research aligns with the goals of our group at Instituto de Química - Unicamp and Center for Innovation on New Energies!

Happy to share the paper that concludes the Ph.D. work developed by Matheus Batista from Campinas Electrochemistry Group - PSF and Gabriela Volpini Soffiati from UMSL (Miguel San-Miguelgroup).

For the oxidation of several organic molecules, it was observed that the modification of Pt with p-block adatoms can increase, have no effect on, or decrease the electrode activity. In this paper, we provided a very reasonable explanation for this phenomenon and paved the way for the rational tuning of Pt surface activity. I hope you enjoy reading it!

Thank you, Center for Innovation on New Energies, Instituto de Química - Unicamp, and Unicamp - Universidade Estadual de Campinas.

Congratulations also to Victor Secco Lemos and Yukuhiro!

"ChatGPT can also be used in a very ethical way, in a very good way. You can use Chat GPT to re-write a sentence in correct English that may have been badly written originally."

"detecting the fact that the text has been written by ChatGPT is, in itself, of no use. You really have to try to find out if the science behind what is written is good. What we need to know is if there is a hallucination, or fake content, or something that should have been done or reported"

Last week, we participated in the "4th ESECS
Workshop on Electrochemistry, from Sensing to Energy Conversion" in São Paulo. The students of Campinas Electrochemistry Group - PSF and Center for Innovation on New Energies Rafael A. Vicente e Victor Yoiti presented the works "Analyzing electrocatalysts in situ with spatially resolved X ray absorption spectroscopy (XAS) and fluorescence (XRF)" and "The effect of alkali cations on the electrooxidation of glycerol on Pt using ATR SEIRAS".
We had two intense days of interesting talks and discussions. We also enjoy some beers in Vila Madalena!!

Tive a oportunidade de acompanhar este Center for Innovation on New Energies Debate desde pertinho da mesa.
Muita informação extremamente rica sobre o passado, presente e o futuro da Economia do Hidrogênio.
No Campinas Electrochemistry Group - PSF formamos alunos com capacidade de solucionar problemas de maneira independente na área de eletroquimica. Com certeza vários trabalharão com H2 no futuro.

Você sabia que o hidrogênio de baixo carbono é fundamental para atingir as metas globais de descarbonização? E que o Brasil é um dos poucos países do mundo c...
