Abstract Transforming carbon dioxide into valuable chemicals and fuels, is a promising tool for environmental industrial purposes. Here, we present catalysts comprising of cobalt (oxide) nanoparticles stabilized on various support oxides hydrocarbon production from dioxide. We demonstrate that the activity selectivity can be tuned by selection oxide oxidation state. Modulated excitation (ME) diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) reveals follows...
Synthesis methods to prepare lower transition metal catalysts and specifically Ni for Shell-Isolated Nanoparticle-Enhanced Raman Spectroscopy (SHINERS) are explored. Impregnation, colloidal deposition, spark ablation have been investigated as suitable synthesis routes SHINERS-active Ni/Au@SiO2 catalyst/Shell-Isolated Nanoparticles (SHINs). precursors confirmed be notoriously difficult reduce the temperatures required generally harsh enough destroy SHINs, rendering SHINERS experiments on...
Methane Dehydroaromatization (MDA) is proposed as a possible way to valorize stranded natural gas, e.g., arising during crude oil drilling. In this study, we used operando UV–Vis Diffuse Reflectance Spectroscopy (DRS) in combination with Multivariate Curve Resolution Alternating Least Squares (MCR-ALS) distinguish the MDA reaction phases of activation, induction, and deactivation. We identified three spectral components, which describe these distinct phases. When catalyst was activated CO,...
