英文摘要Solar cell wafer cutting process produces a lot of silicon carbide-based waste named HT-SiC. Herein, we developed a novel catalyst through a one-pot hydrothermal process combined with an ion-exchange method to synthesize Cu-SSZ-13/HT-SiC composite and applied in denitration catalytic reaction. TMAdaOH and Cu-TEPA were used as templates to prepare the precursor for Cu-SSZ-13, respectively. Results showed that, with participation of HT-SiC, SSZ-13 crystal was successfully obtained by using TMAdaOH template, while it would get only amorphous structure by using Cu-TEPA template. NH3-SCR(Selective Catalytic Reduction, SCR) exhibited catalytic activity and stability of Cu-SSZ-13/HT-SiC in medium and high temperature zones was more effective than those of Cu-SSZ-13 without HT-SiC, and NO consumption by the former was about 11-fold of the latter at 500 degrees C. Moreover, compared with Cu-SSZ-13/alpha-SiC catalyst prepared with pure SiC (alpha-SiC), Cu-SSZ-13/HT-SiC shows better catalytic activity in the whole temperature range. These favorable performances are attributed not only to the good thermal conductivity and thermal stability of SiC, but also to the 7.34wt% Fe component contained in HT-SiC, which acts as an active site for reducing NO in NH3-SCR. This method not only provides a way to reuse the SiC waste, but also enhances denitrification activity of Cu-SSZ-13 in medium and high operating temperature.
