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 °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 °C, hydrogen pressure of 1.3 MPa).

低温水合硅酸铜：用分子氢还原芳香硝基化合物的催化剂

首次在 92–110 °C 下合成的低温水合硅酸铜催化剂上进行了芳香族硝基化合物的氢催化还原。在相对温和的条件下（150-170°C，氢气压力为 1.3 MPa），氢硅酸铜对硝基苯加氢生成苯胺和对二硝基苯加氢生成对硝基苯胺和对苯二胺表现出较高的催化活性和选择性。
