Dual single-atom catalyst design to build robust oxygen reduction electrode via free radical scavenging

Designing Ce single-atom-sites coupled with CeO2 nanoparticles for oxygen reduction enhancement

“…28 It was found that the SA Ce site can also effectively scavenge free radicals. 29 It is concluded that the metal Ce can be used as the primary metal for synthesizing SA catalysts with excellent ORR performance.…”

Machine-Learning-Accelerated Screening of Double-Atom/Cluster Electrocatalysts for the Oxygen Reduction Reaction

“…That is, the Fe- and Ce-based Fe–Ce-0 DAC is predicted to be a potential high-performance ORR catalyst. Note that, in an experimental study, Chu et al reported that the Fe–Ce DAC has a much higher ORR catalytic activity than Fe–N 4 , which agrees with the above calculations. Similarly, Co–Ni-1, Fe–Ni-1, Mn–Cu-0, and Mn–Zn-0, have also been investigated in previous studies showing improvements in ORR activity.…”

Assessing the potential of biochar derived from sewage sludge for photoelectrode fabrication: methods, mechanisms, and conclusions

“…The ˙OH generated can create 1 O 2 on the surface of the photoelectrodes through disproportionation reactions, as shown in eqn (6), contributing to the degradation of TC through non-radical pathways. 60–62 TC was ultimately degraded into small molecules through the pathway described by eqn (7). E CB = E VB − E g BCPE-800 + hν → e − + h + O 2 + 4H + + 4e − → 2H 2 Oh VB + + H 2 O → H + + ˙OH˙OH + ˙OH → 1 O 2 + H 2 Oh + /˙OH/ 1 O 2 + TC → products…”
