求改写几句话，关于电子结构的！

那位高手英文好，请帮助，把下面的一段话，改写一下！谢谢 Mo2C is formed by substituting the oxygen in the molybdenum oxide lattice by carbon. The insertion of carbon into molybdenum lattice causes the contraction of the d-band. Even with fewer electrons, the band is filled to a greater extent and the density of states at the Fermi level is close to those of the Group VIII transition metals, of which the d-band center is closer to the Fermi level. Thus, Mo2C presents similar electronic properties to transition metals. In particular, Mo2C is active and stable for hydrocarbon reforming, accompanied by resistance of sulfur poisoning. Therefore, Mo2C exhibits catalytic properties similar to those of transition metals and can be used as an economic alternative for many other catalytic processes. |
