Abstract Understanding the atomistic structure of active site during catalytic reactions is paramount importance in both fundamental studies and practical applications, but such are challenging due to complexity heterogeneous systems. Here, we use Pt/CeO 2 as an example study dynamic nature sites water-gas-shift reaction (WGSR) by combining multiple situ characterization tools. We show that different concentrations interfacial Pt δ+ – O Ce 4+ moieties at interfaces responsible for rank...
Surface enhanced Raman spectroscopy (SERS) offers ultrasensitive and label-free detection of specific molecules with broad applications in chemistry, life sciences, security, environmental sensors. Among contaminants, Hg2+ poses a significant threat due to its high toxicity, necessitating precise high-throughput methods. Here, we introduce novel SERS chip that integrates multiwell plate plasmonic array, boasting strong electromagnetic enhancement exceptional uniformity. Through surface...
Metal-organic frameworks (MOFs) offer an intrinsically porous and chemically tunable platform for gas adsorption, separation, catalysis. We investigate thin film derivatives of the well-studied Zr-O based MOF powders to understand their adsorption properties reactivity with adaption films, involving diverse functionality incorporation different linker groups inclusion embedded metal nanoparticles: UiO-66, UiO-66-NH2, Pt@UiO-66-NH2. Using transflectance IR spectroscopy, we determine active...
The conversion of biomass to transportation fuels and value-added chemicals is a promising method reduce the reliance on fossil fuels. Mo-based catalysts have been shown be highly active in hydrodeoxygenation biomass-derived phenolic compounds. catalyst phase, surface species, effect adding additional metals are not comprehensively understood. Here we compare temperature-dependent adsorption behavior model compound anisole an alumina-supported mixed nickel molybdenum oxide with two reference...
