用由Cr和另一种过渡金属组成的双组分助催化剂进行改性，以试图提高（Ga 1-xZn x）（N1-xOx）的光催化活性。用各种过渡金属改性的（Ga 1-xZnx）（N1-xOx）的活性通过Cr的共负载而增强，尽管单独用Cr改性对促进该反应中的活性无效。发现共负载的催化剂的活性强烈地依赖于负载的Cr的量，这又根据成对的过渡金属而变化。活性的提高归因于通过Cr和配对金属组分之间的密切相互作用形成合适的反应位点。(c)2006年爱思唯尔公司All rights reserved.
Modification with a two-component cocatalyst consisting of Cr and another transition metal was examined in an attempt to improve the photocatalytic activity of (Ga1-xZnx)(N1-xOx) for overall water splitting. The activity of (Ga1-xZnx)(N1-xOx) modified with various transition metals is enhanced by co-loading of Cr, although modification with Cr alone is not effective for promoting activity in this reaction. The activity of the co-loaded catalyst is found to be strongly dependent on the amount of loaded Cr, which in turn varies according to the paired transition metal. The improvement in activity is attributed to the formation of suitable reaction sites by intimate interaction between Cr and the paired metal component. (c) 2006 Elsevier Inc. All rights reserved.
