vi

Experimental results indicate that the reduction reaction can be carried out in a heterogeneous system with a lower reaction temperature and shorter reaction time. This kind of hybrid material is easy to prepare and structurally design, and has the potential to replace precious metals such as Pt/Pd nanoparticles used in this field. |
