About 50 (when testing below higher humidity conditions, the relative humidity was maintained at about 75 ). Ahead of the simulated sunlight irradiation, 45 min of dark reaction was carried out to attain the SJ995973 medchemexpress adsorptiondesorption equilibrium around the surface of the composites. Then, the catalytic procedure was examined having a light intensity of 50 mW/cm2 in the sample surface. Typically, the degradation price of formaldehyde was equal towards the formation price of CO2 , thus the degradation price of formaldehyde may be calculated in line with the following formula: D= M1 CO2 . M2 C0 (1)M1 and M2 represent the relative molecular weights of formaldehyde and carbon dioxide, respectively. CO2 is definitely the increment of CO2 (mg/m3 ). C0 represents the initial concentration of formaldehyde (mg/m3 ), plus the theoretical calculation value is 66.8mg/m3 . The concentration of CO2 and formaldehyde was monitored through a photoacoustic spectrum. 3. Outcomes and Discussion 3.1. Cation Exchange Impact of Catalyst Due to the fact NC possessed a superior cation exchange impact, it’s necessary to further investigate irrespective of whether the cation exchange efficiency is conducive to the growth of BiOCl, which is essential for understanding the mechanism on the catalyst. A specific quantity of NC-Na-3.0 was transferred into Bi(NO3 )3 ethylene glycol solutions and the suspension was dispersed evenly beneath vigorous stirring. Then, the suspension was transferred to a water bath at 0 C and 90 C, respectively. After stirring for two h, the suspension was filtrated and dried, then the as-prepared composites had been marked as CN-0 and CN-90, respectively. The chemical elements in the above two samples have been additional analyzed. As shown in Table 1, the content material of Bi in CN-0 and CN-90 was higher than NC-Na-3.0, while the content material of Na and Ca in CN-0 and CN-90 are considerably decrease than NC-Na-3.0, indicating that ion-exchangeable reaction among the Na+ , Ca2+ in NC-Na-3.0 and Bi3+ was carried out. Moreover, there is tiny difference in the chemical elements in between CN-0 and CN-90, indicating that a low temperature could hardly inhibit the ion exchange among Na+ , Ca2+ in NC-Na-3.0 and Bi3+ .Table 1.
