Support structure: In the presence of gold nanoparticles supported on alumina (Au/Al2O3), various hydrosilanes can be converted into the corresponding silyl isocyanates using urea as an isocyanate source. The observed catalysis is truly heterogeneous, and the retrieved Au/Al2O3 catalyst can be reused several times without any loss of its high catalytic performance.
载体结构:在金纳米颗粒负载在氧化铝(Au / Al 2 O 3)上的情况下,可以使用尿素作为异氰酸酯源将各种氢硅烷转化为相应的甲硅烷基异氰酸酯。观察到的催化确实是非均相的,并且回收的Au / Al 2 O 3催化剂可以重复使用几次,而不会损失其高催化性能。
