We show that lead oxide clusters are easily broken down upon addition of small amounts of carbon and the resulting graphitic matrix, dispersed with weakly bound and exposed Pb sites, acts as a Lewis acid to bind small molecule Lewis bases such as NO and CHO that form in the combustion flame. This accounts for super-rate burning, where the fuel burn rate is enhanced.
