Our recent mechanistic investigation of the electrochemical CO reduction on Cu suggests C-C coupling is no the rate limiting step. Reaction order of adsorb CO never reaches 2 despite of our best efforts. Check it out at: https://t.co/SP2Ez3elLi

Happy to share our recent work on the cation effect in the CO2RR, which is highlighted as a cover work in @ACSCatalysis We show that an existing theory is unlikely to hold but truth of how cations impact electrocatalytic reactions is still out there! https://t.co/Ynx0JyUa0f

First paper in 2020 came out on renewable adipic acid production @UDChBE, and it came out two years after the first author (Matt Gilkey) graduated! https://t.co/65qdf7QMwe

Adipic acid (AA) is an important precursor for the production of Nylon-66, and renewable routes for AA are being explored. Previously we have shown the use of HI and molecular H2 to be an effective...

Our recent work @UDChBE in @ACSCatalysis demonstrates the molecular intimacy between acid and metal sites is key to mediating tandem catalysis:
pubs.acs.org
The proximity of different catalytic sites is key to selective catalysis; however, the controlled placement of multiple types of active sites is synthetically challenging. In this work, we show that...

Our work @UDChBE @UDengineering on the impact of the forced convection on spectroscopic observations in CORR came one line in @ACSCatalysis. The key take home message is that stirring matters in correlating spectroscopic with reactivity results.
pubs.acs.org
The electrochemical CO reduction reaction (CORR) has been shown to suffer from mass transport limitations owing to the low solubility of CO in aqueous electrolytes (∼1 mM). However, no direct...

A 50y old memo wrote by our department legend T W Fraser Russell, who passed away last week. Some good points are still relevant even after almost fifty years.
