A composite material (FeSIL) prepared by FeCl3-imidazolium ionic liquid grafted on SBA-15 exhibited effective catalytic activity for solvent-free oxidation of styrene into benzaldehyde with high selectivity using H2O2 oxidant and it presented easy recovery and reusability. In situ DRIFTS spectra for styrene and H2O2 adsorption showed that an intermediate Fe3+–π surface complex on the catalyst surface...
This paper reported synergistic bimetallic AuCu/TiO2 catalysts for selective oxidation of 1,2-propanediol to lactic acid under very mild conditions (T < 90 °C, 1 MPa O2). The addition of Cu to monometallic Au/TiO2 catalyst leads to a twofold activity enhancement for Au catalysts (TOF: 11894 h−1) with good selectivity towards lactic acid (S > 92%). Surface characterization reveals that while...
This paper aims at investigating a new method for the detection of DNA with catalytic beacons based on peroxidase-oxidase (PO) oscillation and analytic pulse perturbation technique. Two DNAzymes were constructed by the binding of specific DNA sequence with hemin or by the hybridization of target DNA with the catalytic beacon. Both DNAzymes possessed peroxidase-like activity and perturb the PO oscillator...
