Applications of high-resolution scanning probe microscopy in hydroprocessing catalysis studies

摘要: Abstract Scanning probe microscopy offers real space atomic and nanoscale imaging of surfaces supported nanoparticles, these techniques are used in a planar catalyst model system context to analyze important atomic-scale aspects nanoparticle structure, particle edges, defects, vacancies image the resulting interaction individual reactants with active surfaces. Here we review applications high-resolution scanning hydroprocessing catalysis, demonstrate how atom-resolved have recently advanced become tools that elucidate catalytically edge structures metal sulfide hydrotreating catalyst, resolve intramolecular structure complex hydrocarbons, provide information on mechanisms which heteroatom-bearing hydrocarbons interact particle. This mini-review addresses advantages tunneling for studies systems relevant including emerging use near-ambient pressure (operando) together examples low-temperature molecular non-contact force microscopy.
