Chemistry on water is a fascinating area of research. The surface of water and the interfaces between water and air or hydro-phobic media represent asymmetric environments with unique properties that lead to unexpected solvation effects on chemi-cal and photochemical processes. Indeed, the features of interfacial reactions differ, often drastically, from those of bulk-phase reactions. In this perspective, we focus on photoinduced oxidation reactions, which have attracted enormous interest in recent years because of their implications in many areas of chemistry, including atmospheric and environmental chemistry, biology, electrochemistry, and solar energy conversion. We have chosen a few representative examples of photoinduced oxidation reactions to focus on in this perspective. Although most of these examples are taken from the field of atmospheric chemistry, they were selected because of their broad relevance to other areas. First, we outline a series of processes whose photochemis-try generates hydroxyl radicals. These OH precursors include reactive oxygen species, reactive nitrogen species, and sulfur dioxide. Second, we discuss processes involving the photooxidation of organic species, either directly or via photosensitiza-tion. The photochemistry of pyruvic acid and fatty acid, two examples that demonstrate the complexity and versatility of this kind of chemistry, is described. Finally, we discuss the physicochemical factors that can be invoked to explain the ki-netics and thermodynamics of photoinduced.

气水界面的光致氧化反应

水化学是一个引人入胜的研究领域。水的表面以及水与空气或疏水介质之间的界面代表具有独特性质的不对称环境,这些环境会导致对化学和光化学过程产生意想不到的溶剂化作用。事实上,界面反应的特征通常与体相反应的特征大不相同。从这个角度来看,我们专注于光致氧化反应,由于它们在许多化学领域的影响,包括大气和环境化学、生物学、电化学和太阳能转换,近年来引起了极大的兴趣。我们选择了一些光诱导氧化反应的代表性例子来关注这个角度。尽管这些例子大部分取自大气化学领域,但之所以选择它们,是因为它们与其他领域具有广泛的相关性。首先,我们概述了一系列光化学产生羟基自由基的过程。这些 OH 前体包括活性氧物质、活性氮物质和二氧化硫。其次,我们讨论了涉及有机物种光氧化的过程,直接或通过光敏化。描述了丙酮酸和脂肪酸的光化学,这两个例子证明了这种化学的复杂性和多功能性。最后,我们讨论了可以用来解释光致动力学和热力学的物理化学因素。我们概述了一系列光化学产生羟基自由基的过程。这些 OH 前体包括活性氧物质、活性氮物质和二氧化硫。其次,我们讨论了涉及有机物种光氧化的过程,直接或通过光敏化。描述了丙酮酸和脂肪酸的光化学,这两个例子证明了这种化学的复杂性和多功能性。最后,我们讨论了可以用来解释光致动力学和热力学的物理化学因素。我们概述了一系列光化学产生羟基自由基的过程。这些 OH 前体包括活性氧物质、活性氮物质和二氧化硫。其次,我们讨论涉及有机物种光氧化的过程,直接或通过光敏化。描述了丙酮酸和脂肪酸的光化学,这两个例子证明了这种化学的复杂性和多功能性。最后,我们讨论了可以用来解释光致动力学和热力学的物理化学因素。直接或通过光敏化。描述了丙酮酸和脂肪酸的光化学,这两个例子证明了这种化学的复杂性和多功能性。最后,我们讨论了可以用来解释光致动力学和热力学的物理化学因素。直接或通过光敏化。描述了丙酮酸和脂肪酸的光化学,这两个例子证明了这种化学的复杂性和多功能性。最后,我们讨论了可以用来解释光致动力学和热力学的物理化学因素。
