摘要/Abstract

摘要：

利用静电吸附作用在二氧化钛纳米片上负载铂原子制备了两种不同形态的铂催化剂。SEM、XRD、TEM测试结果表明, 改变铂负载量可以调控铂的形貌结构。在低Pt负载(0.2wt%)下, 铂原子主要是半径约2 nm的纳米簇, 当Pt负载量增加到1wt%时, 铂原子在二氧化钛纳米片上堆积成纳米颗粒。调控Pt负载量和纳米结构, 可以显著提高二氧化钛纳米片催化析氢反应的活性。在AM1.5太阳光照射下, 两种催化剂的塔菲尔斜率都小于100 mV/dec, 分别为56和90 mV/dec。与TiO₂-Pt1%催化剂相比, TiO₂-Pt0.2%具有更理想的金属-半导体界面, 有利于光生电子迁移至铂纳米簇表面, 因而具有更高的催化活性。本实验为研究更加高效的铂催化剂和其他光电催化剂提供了新的途径。

Abstract:

Two kinds of platinum catalysts with different morphologies were prepared by loading platinum atoms on titanium dioxide nanosheets via electrostatic adsorption. Scanning electron microscope (SEM), X-ray powder diffraction (XRD) and transmission electron microscope (TEM) characterization show that the morphology and structure of platinum could be controlled by changing the platinum loading. With low Pt loading (0.2wt%), the platinum atoms were mainly nanoclusters with a radius of about 2 nm. When the Pt loading increased to 1wt%, the platinum atoms stack into nanoparticles on the titanium dioxide nanosheets. The catalytic hydrogen evolution activity of titanium dioxide nanosheets can be improved obviously by regulating the platinum loading and nanostructure. Under AM1.5 solar light, the Tafel slope of both catalysts were less than 100 mV/dec, i.e. 56 and 90 mV/dec, respectively. Compared with TiO₂-Pt1% catalyst, TiO₂-Pt0.2% has a more ideal metal-semiconductor interface, which is favorable for photogenic electrons to migrate to the surface of platinum nanoclusters, and thus perform a higher catalytic activity. This experiment provides a new way for preparing platinum catalysts with high efficiency.
