Abstract

Abstract: Through the modification of mesoporous silica (SBA-15), a hydrophobic microscopic reaction environment was constructed, which was beneficial to improve the catalytic activity of the LPCE reaction. The Pt@SBA-15-tetramethyldisilazane catalyst is prepared by the modification of the SBA-15 carrier and the loading of metal Pt, with a water contact angle of 158°. This superhydrophobic structure can enhance the catalytic performance and can prevent the deactivation of the catalyst. By measuring the actual catalytic performance of tritium water under different conditions, we found that it has good catalytic activity, and the catalyst can still maintain a high catalytic activity after 30 days in tritium water environment. Highlights: The superhydrophobic SBA-15 support was synthesized by the modification of silane coupling agent. Spherical porous self-supporting hydrophobic catalysts were successfully prepared. The hydrogen-water isotope exchange was used to evaluate the catalytic performance in tritium water. The high performance and stability of the catalyst show promise in tritium water treatment.
