Biomass‐Derived Porous Carbon as an Enzyme Mimic for Colorimetric Detection of Ascorbic Acid

Abstract: Powder porous carbon (PPC) has been fabricated by using corncob, a by-product of corn production, through a simple calcination process. The relevant carbon material retains an intrinsic porous structure and has a large specific surface area of 577.15 m 2 /g. The oxidase-like and peroxidaselike activities of porous carbon based on corncob are explored in the pH range of 2.0-8.0, and temperature between 15 and 60 °C, and are optimal at physiological temperature. According to fluorescence and scavenger meas-ureme… Show more

“…Enzyme-like materials are widely studied and considered as excellent substitutes for natural enzymes due to their unique structure and properties. Enzyme-like materials include metal oxides, metal sulfides, metal–organic frameworks (MOFs), carbon-based materials, etc. Among them, cobalt-based materials such as Co 3 O 4 , Co-MOF, and CoS have shown enzyme-like properties because of their remarkable physicochemical properties .…”
