Some recent stuff on electrocatalysis: a wonderful demonstration of how a mononuclear cobalt complex can efficiently catalyze OER (doi.org/10.1021/acsmat…), following overall water splitting by an activated Co4 cluster at a very low cell overpotential (doi.org/10.1021/acscat…)

Our paper on single atom catalyst is published in Chemistry of Materials . Congrats Zheng-Da He for the great work. We made all DFT raw data and the predicted overpotential for 280 systems available in GitHub repo (github.com/Jeff-oakley/SA…).

A special gem indeed – my inaugural article since joining IITK (written after joining IITK)! Stay tuned for further updates in the final rendition! 🚀

An important difference in dynamics of reacting systems is that oscillating temperature or oscillating overpotential are changing the overall reaction thermodynamics, while programmable catalysis is only changing the adsorbed surface species energy.

Interesting! As early as 1987, Michael Graetzel observed that photocatalytic water splitting actually produced H2 and H2O2. It's a kinetically favoured 2e- process as compared to 4e- process of water oxdn to O2 which requires a much larger overpotential.

Yesterday at #FDNitrogen Faraday Discussions Olivia Westhead gave a highly illuminating account of her experiments explaining the origin of overpotential in Li mediated N2 reduction (hint: it’s the Li plating).

Immanuel Cunt Poin kedua, serious answer:

Pure H2 (fossil based H2) msh jd opsi krn potensi hi energynya menggiurkan, despite it's safety.

Tp klo sumbernya elektrolisis air, maka overpotential masih jd issue. Yes, dah ada upaya riset buat resolve masalah ini. Tp over ttp lah over...
