چکیده
Peroxidase enzymes are crucial in analytical chemistry owing to significant peroxide analytes and their key role hydrogen (H2O2) detection. Therefore, exploiting appropriate catalysts for the peroxidase like reactions has become achieving desired performance. Zirconium (Zr) attracted growing interest, as a safe stable potential eco-friendly catalyst various organic transformations that address increasing environmental challenges. Hence, aiming at fast, sensitive selective optical detection of H2O2, colorimetric platform is presented here, based on excellent enzyme-like activity Zr decorated graphene oxide (GO). The synergistic effect achieved due intimate contact between an enzyme high surface area 0f GO ensures efficient electron transfer increases chemical catalytic composite advances decomposition H2O2 into hydroxyl radicals. designed probe, thus, efficiently catalyzes oxidation 3,3′,5,5′-tetramethylbenzidine (TMB), via radicals, thereby transforming colorless TMB blue oxidized within 2 min. mechanism Zr-GO mimic proposed herein verified using fluorescent probe terephthalic acid (TA) other scavenger experiments. multifunctional allows highly recognition linear range from 100 1000 µM with low limit 0.57 µM. Essentially, direct accessibility prevents having use complicated preparation purification procedures mostly practiced conventional biozymes nanozymes. devised method offers several gains, including being green inexpensive catalyst, lower LOD, cost-effective sensitive, work-up procedures.
