研究了金粒子在几种光催化剂上的光沉积对光催化活性的影响。K_4Nb_6O_（17）、Sr_2Nb_2O_（7）、KTaO_3、NaTaO_3和La掺杂的NaTaO_3的光催化分解水的活性随着金粒子的沉积而提高。后者是纳米颗粒，与它们的表面等离子体吸收一致。纳米金颗粒作为一种高效的助催化剂，通过辅助H2-的释放，用于光催化水裂解。
The effect of the photodeposition of gold particles onto several photocatalysts on the photocatalytic activities was studied. The photocatalytic activities of K4Nb6O17, Sr2Nb2O7, KTaO3 NaTaO3, and NaTaO3 doped with La for water splitting were improved when gold particles were deposited. The latter were nanoparticles, consistent with their surface plasmon absorption. The nanosized gold particle functioned as an efficient cocatalyst for photocatalytic water splitting by assisting H-2 evolution.
