《Fast and low-temperature elimination of organic templates from SBA-15 using dielectric barrier discharge plasma》
Figure 7 shows the thermo gravimetric（TG）analysis results of all samples in the temperature range from 150°C to 800°C.It should be noted that the weight losses below 200°C，assigned mainly to the physically adsorbed and chemically adsorbed water，were nearly the same for C-SBA-15 and DBD-SBA-15. The weight loss about 200°C would be attributed mainly to the dehydroxylation by condensation of silanol groups[23].The weight losses corresponding to the as-synthesized，plasma treated and calcinations treated SBA-15 were 39.3%，8.3%and5.5%，respectively.Therefore，the DBD plasma method can efficiently remove the template at a relatively low temperature，which will abundantly preserve the Si–OH groups and avoid the shrinkage of the frame structure of SBA-15.Further studies on the impact of particle size on the performance of the DBD treatment are currently underway in our laboratory.
