ball mill hydrogenation

Ball milling Au and Pd or Au and Cu in a high-energy regime (shaker mill) indeed led to the formation of Au–Pd and Au–Cu nanoparticles, supported on MgO or yttria-stabilized zirconia (YSZ), which were explored as model systems. Powder X-ray diffraction and electron microscopy were the primary means to investigate as-synthesized materials

We believes the value of brand, which originates from not only excellent products and solutions, but also considerate pre-sales & after-sales technical services. After the sales, we will also have a 24-hour online after-sales service team to serve you. please be relief, Our service will make you satisfied.
