摘要：
The catalytic reduction of aromatic nitro compounds with hydrogen was carried out for the first time over low-temperature copper hydrosilicates synthesized at 92-110 degrees C as catalysts. Copper hydrosilicates demonstrated high catalytic activity and selectivity towards nitrobenzene hydrogenation to aniline and p-dinitrobenzene hydrogenation to p-nitroaniline and p-phenylenediamine under relatively mild conditions (150-170 degrees C, hydrogen pressure of 1.3 MPa).
