文摘

Operando spectroscopy of catalytic solid-liquid-gas reaction systems is achieved. Choice of the support material of a powder catalyst is crucial for spectroscopic analysis. Chiral modifier surface coverage can be correlated to enantioselectivity. Cinchonidine adsorbed to Pt with a tilted quinoline ring is relevant for enantioselection.
