Photoswitchable Catalytic Aerobic Oxidation of Biomass-Based Furfural: A Selective Route for the Synthesis of 5-Hydroxy-2(5H)-furanone and Maleic Acid by Using the CdS/MOF Photocatalyst

“…Home-made photo reactor apparatus; the elemental composition of photocatalysts based on XPS; obtained results from BET for photocatalysts; obtained results from bandgap calculation for synthesized photocatalysts; 1 H and 13 C NMR spectra of the reaction mixtures (PDF)…”

“…To address the energy crisis and environmental concerns, catalytic upgrading of renewable lignocellulosic biomass to highly valued chemicals and liquid fuels is gaining more and more attention. 12,13 Considering that hydrocarbons are the major part of biomass and the largest natural source of carbon, and hexoses, or six-carbon hydrocarbons such as glucose, fructose, etc., are the most abundant monosaccharides in nature, we decided that one of the chemical compounds based on furan ring with high added value that is obtained from biomass and has a high pollution effect should be chosen for the oxidation reaction under visible light irradiation. 14−16 Biomass-based furfural has received a lot of attention as the most attractive biomass resource with a great potential for conversion into useful chemicals due to the increasing need for renewable biomass sources as a potent substitute to fossil-based feedstocks.…”

“…The ultraviolet−visible diffuse reflectance spectrum (DRS) was recorded by the V_670-JASCO spectrometer (Japan) in the 200−800 nm wavelength range. The NMR spectra for catalytic products were obtained using a Bruker advanced DPX-250 spectrometer in DMSO-d6 operating for 1 H at 400 MHz and for 13 C at 400 MHz.…”

“…This led to the expansion of the use of renewable energy sources, such as biomass, solar energy, wind energy, hydropower, and nuclear radiation due to their extensive power, short regeneration periods, and ubiquitous presence as sustainable sources. − Among these energy sources, biomass is the only renewable carbon reservoir and the most abundant source in the biosphere; therefore, it is considered as an ideal candidate to help change the traditional fossil sources for the production of chemicals and fuels. − A potential long-term solution to the aforementioned global issues is the synthetically efficient utilization of renewable and carbon-neutral biomass resources, which also helps to improve the ecological environment and optimize the energy structure while fixing carbon dioxide in the carbon cycle system. To address the energy crisis and environmental concerns, catalytic upgrading of renewable lignocellulosic biomass to highly valued chemicals and liquid fuels is gaining more and more attention. , Considering that hydrocarbons are the major part of biomass and the largest natural source of carbon, and hexoses, or six-carbon hydrocarbons such as glucose, fructose, etc., are the most abundant monosaccharides in nature, we decided that one of the chemical compounds based on furan ring with high added value that is obtained from biomass and has a high pollution effect should be chosen for the oxidation reaction under visible light irradiation. − …”
