Main group elements in electrochemical hydrogen evolution and carbon dioxide reduction

Abstract

Main-group elements are renowned for their versatile reactivities in organometallic chemistry, including CO2 insertion and H2 activation. However, electrocatalysts comprising a main-group element active site have not yet been widely...

Low oxidation state and hydrido group 2 complexes: synthesis and applications in the activation of gaseous substrates

“…206–208 Consequently, the stoichiometric reduction of carbon dioxide has received considerable attention in molecular main-group chemistry, while effective catalytic applications remain comparably rare. 209,210 Within this context, low oxidation state and hydrido alkaline earth metal complexes have established themselves as potent reductants of carbon dioxide. 13,66…”

Steady Cu+ species via magnesium and boron co-modification for enhanced CO2 electroreduction to C2+ products: an in situ Raman spectroscopic study

“…30 Alkaline-earth metals such as Mg, Ba and Ca were found to not only maintain Cu + on catalyst surfaces, but also enhance the adsorption of intermediates at active centers, thereby influencing the reaction kinetics of the CO 2 RR process. 31 For instance, Peng et al synthesized a nano-Cu 2 Mg intermetallic catalyst predominantly oriented along the (111) crystal face on a carbon black substrate (denoted as Cu 2 Mg(111)). In situ Raman spectroscopy and DFT calculations confirmed that the Cu 3 δ − –Mg δ + active sites in Cu 2 Mg(111) enhanced the coverage of *CO on the catalyst surface, lowered the energy barrier for *CO–CO coupling, and stabilized the *CHCHOH intermediates to promote ethanol production.…”

A N-doped carbon-supported In2O3 catalyst for highly efficient CO2 electroreduction to HCOOH

“…The electrochemical CO 2 reduction reaction (CO 2 RR) holds the promise of directly converting CO 2 into valuable fuels and raw materials, achieving carbon neutrality and reducing our reliance on fossil fuels. 1,2 Among the various potential products, HCOOH is an important chemical due to its potential applications as an energy storage medium and fuel. 3 Through reasonable catalyst design and reaction condition optimization, achieving efficient HCOOH product has opened up broad prospects for the sustainability and economic viability of the CO 2 RR.…”
