Structural and surface coverage effects on CO oxidation reaction over carbon-supported Pt nanoparticles studied by quadrupole mass spectrometry and diffuse reflectance FTIR spectroscopy
Abstract:The CO oxidation reaction on carbon-supported Pt nanoparticles (average size of 2.8 to 7.7 nm) was studied under flowing conditions at atmospheric pressure and temperatures between 300 and 353 K by coupling quadrupole mass spectrometry (QMS) and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). The Pt loading was varied between 20 and 60 wt%. Gases diluted in He (0.5 mol%) were used together with Ar as a tracer. Reactions with CO and O2 introduced separately onto the samples were studied by… Show more

[6][7][8][9] Since graphene was successfully manufactured, various new 2D materials have been used in electronics, batteries and composite materials due to their unusual electronic and optical properties, strong quantum effects and dimension reduction. 10,11 C 2 N is one of the family members in hexagonal carbon nitride, which has been efficiently synthesized via a simple bottom-up wet-chemical reaction.…”
The problem of poisoning on the surface of catalysts used in CO oxidation reactions, such as Pt, needs to be solved. In this work, we constructed lattice-matched C2N/Pt(111) catalysts with...
