Based on phthalocyanines --SnO2 as a photo catalyst, this paper uses the degrading difference of thiophene by various catalysts under ultraviolet and visible light irradiation conditions to compare the catalytic effects of the different phthalocyanine compounds --SnO2 photosensitive catalysts, and summarize the reasons and laws to influence the catalysts’ catalytic performance, and analyze the kinetic process of photocatalytic oxidation reaction, and initially discuss kinetics of photocatalytic oxidation reaction and its products.

<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>
