the authors proposed a unique hybrid process combining solar irradiation and post-plasma catalysis (PPC) to effectively oxidize toluene over a stable, highly active MnO2/bifunctional graphene fin foam (GFF) catalyst. the bifunctional GFF, serving as catalyst support and light absorber, was decorated with MnO2 nanofins to form a hierarchical fin-on-fin structure. results showed the MnO2/GFF catalyst effectively captures/converts renewable solar energy into heat (>95% absorption), leading to a temperature rise (55.6°) of the catalyst bed from solar irradiation (1 sun, 1000 W/m2 light intensity). catalyst weight (9.8 mg) was significantly lower (10-100 times lower) than that used in previous studies (usually 100-1000 mg). introducing solar energy into the typical PPC process via solar thermal conversion significantly enhanced toluene conversion and CO2 selectivity (36-63%), reaching ∼93% for toluene conversion and ∼83% for CO2 selectivity at ∼350 J/L specific input energy to remarkably reduce the energy consumption of the plasma-catalytic gas cleaning process. toluene conversion energy efficiency for solar-enhanced post-plasma catalytic (SEPPC) process was up to 12.7 g/kWh, ∼57% higher than that using the PPC process without solar irradiation (8.1 g/kWh); SEPPC process energy consumption was reduced 35-52%. the MnO2/GFF catalyst exhibited excellent self-cleaning induced by solar irradiation, demonstrating superior long-term catalytic stability (72 h at 1 sun), significantly better than that reported in previous work. the prominent synergistic effect of solar irradiation and PPC with a synergistic capacity of ∼42% was mainly attributed to the solar-induced thermal effect on the catalyst bed, boosting O3 decomposition (nearly a three-times enhancement from ∼0.18 gO3/g-hr for PPC to ∼0.52 gO3/g-hr for SEPPC) to generate more oxidative species (e.g., O-) and enhancing on-surface catalytic oxidation as well as the catalyst self-cleaning capacity at solar radiation-induced elevated temperatures this work provides a rational route to use abundant, renewable solar power for high performance, energy-efficient volatile organic compounds removal.Methyl 3-hydroxypropanoate(cas: 6149-41-3Quality Control of Methyl 3-hydroxypropanoate) was used in this study.
Methyl 3-hydroxypropanoate(cas: 6149-41-3) belongs to esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
