In comparison with the Co analog, small Fe clusters incorporated in a graphene matrix exhibit a photo-assisted increase of 110% in reverse water gas shift CO hydrogenation under UV-Vis light irradiation. Available data indicate that the photo-assistance derives from light absorption by the N-doped graphene followed by charge recombination at the Fe clusters, increasing their local temperature.
与钴类似物相比，掺入石墨烯基质中的小铁簇在紫外-可见光照射下，逆水煤气变换CO加氢反应中表现出110%的光辅助增加。现有数据表明，光辅助源于氮掺杂石墨烯对光的吸收，随后在铁簇处发生电荷复合，从而提高了它们的局部温度。
