Unlike other Ru-containing compounds whose active sites are Ru sites, the Si sites in LaRuSi function as real active sites. The unusual negative valence Ru in this compound has excessively tight adsorption for hydrogen, according to both theoretical calculations and in situ Raman observations, but the Si sites have excellent hydrogen adsorption properties.

由负价 Ru 启用的高活性 Si 位点用于​​ LaRuSi 中的电催化析氢

与其他活性位点为 Ru 位点的含 Ru 化合物不同，LaRuSi 中的 Si 位点起到真正的活性位点的作用。根据理论计算和原位拉曼观察，该化合物中不寻常的负价Ru对氢的吸附过于紧密，但Si位点具有优异的氢吸附性能。
