Fast Flow Reactor

Reactions of F(2P) atoms generated by a 2.45 GHz discharge in dilute F2 + He mixtures have been studied mass spectrometrically with a beam inlet system from a fast flow reactor. F atom concentrations have been measured from the consumption of Cl2 in the simple and extremely rapid bimolecular reaction 1[Formula: see text]k1 was determined to be (1.1 ± 0.3) × 10−10 cm3 molecule−1 s−1 at 300 °K.Rate measurements for the reaction 2, which forms CF3 radicals, are reported, over the range 301 to 667 °K,[Formula: see text][Formula: see text]A less detailed survey of the rates at 298 °K of a series of reactions of F with H2, CH4, CH3Cl, CH2Cl2, and CHCl3, is also given; in these cases, the source of F was a discharge in CF4 + Ar, and [F] was measured by titration with ClNO.

<p><i>Operando</i> spectroelectrochemical analysis is used to determine the water oxidation reaction kinetics for hematite photoanodes prepared using four different synthetic procedures. Whilst these photoanodes exhibit very different current / voltage performance, their underlying water oxidation kinetics are found to be almost invariant. Lower photoanode performance was found to correlate with the observation of optical signals indicative of charge accumulation in mid-gap oxygen vacancy states, indicating these states do not contribute directly to water oxidation.</p>

The course of the conversion of methanol with water vapour was followed on a low-temperature Cu-Zn-Cr-Al catalyst at pressures of 0.2 and 0.6 MPa. The kinetic data were evaluated together with those obtained at 0.1 MPa and the following equation for the reaction kinetics at the given conditions was derived: r = [p(CH3OH)p(H2O)]0.5[p(H2)]-1.3.
