Abstract

In this joint experiment-theory work the adsorption of organophosphonic acids on

α

-Bi

surfaces is studied by means of X-ray photoelectron spectroscopy (XPS), diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), as well as density functional theory (DFT). The present results demonstrate the formation of a full bidentate-bonded monolayer structure with an all-trans configuration of the aliphatic chains, whereby the evolution of the monolayer can be monitored via the shape of XPS spectra. Our results for the model oxide are a basis for the surface modification of oxide covered Bi with functional organophosphonic acids.

磷酸在α-Bi2O3表面的吸附

本文采用x射线光电子能谱（XPS）、漫反射红外傅立叶变换光谱（DRIFTS）和密度泛函理论（DFT）研究了有机膦酸在α-Bi2O3表面的吸附。目前的结果表明，形成了具有脂肪链全反式构型的完整双齿键单层结构，通过XPS光谱的形状可以监测单层结构的演变。我们对模型氧化物的研究结果为用功能性有机膦酸对氧化铋进行表面改性奠定了基础。

期刊介绍： Surface Science is devoted to elucidating the fundamental aspects of chemistry and physics occurring at a wide range of surfaces and interfaces and to disseminating this knowledge fast. The journal welcomes a broad spectrum of topics, including but not limited to: • model systems (e.g. in Ultra High Vacuum) under well-controlled reactive conditions • nanoscale science and engineering, including manipulation of matter at the atomic/molecular scale and assembly phenomena • reactivity of surfaces as related to various applied areas including heterogeneous catalysis, chemistry at electrified interfaces, and semiconductors functionalization • phenomena at interfaces relevant to energy storage and conversion, and fuels production and utilization • surface reactivity for environmental protection and pollution remediation • interactions at surfaces of soft matter, including polymers and biomaterials. Both experimental and theoretical work, including modeling, is within the scope of the journal. Work published in Surface Science reaches a wide readership, from chemistry and physics to biology and materials science and engineering, providing an excellent forum for cross-fertilization of ideas and broad dissemination of scientific discoveries.
