Comprehensive analysis of common polymers using hyphenated TGA-FTIR-GC/MS and Raman spectroscopy towards a database for micro- and nanoplastics identification, characterization, and quantitation

Environmental contamination by micro- and nanoplastics (MNPs) is well documented with potential for their increased accumulation globally. Growing public concern over environmental, ecological, and human exposure to MNPs has led to exponential increase in publications, news articles, and reports (Casillas et al., 2023). Significant knowledge gap exists in standardized analytical methods for the identification and quantification of MNPs from real world environmental samples.
CO2 coverage on Pd catalysts accelerates oxygen removal in oxy-combustion systems

Oxy-combustion systems result in enriched CO2 in exhaust gases; however, the utilization of the concentrated CO2 stream from oxy-combustion is limited by remnant O2. CH4 oxidation using Pd catalysts has been found to have high O2-removal efficiency. Here, the effect of excess CO2 in the feed stream on O2 removal with CH4 oxidation is investigated by combining experimental and theoretical approaches.
Characterization of flame synthesized Pd–TiO2 nanocomposite catalysts for oxygen removal from CO2-rich streams in oxy combustion exhausts
Catalysis Science & TechnologyJung, et al.
2021-06-09
Pd–TiO2 catalysts with five Pd loadings were synthesized using a flame aerosol reactor. Studies of the initial and spent catalysts demonstrate that Pd loading impacted the size of Pd sub-nano clusters/nanoparticles and the fraction of Pd (metallic Pd, PdO, PdOx). Increased size of Pd on catalysts' surface due to sintering, and the reduction of PdO to metallic Pd and/or PdOx were observed during the reaction
