Relevant data on heterogeneous surface recombination of neutral oxygen atoms available in the scientific literature are reviewed and discussed for various materials. The coefficients are determined by placing the samples either in non-equilibrium oxygen plasma or its afterglow. The experimental methods used to determine the coefficients are examined and categorized into calorimetry, actinometry, NO titration, laser-induced fluorescence, and various other methods and their combinations. Some numerical models for recombination coefficient determination are also examined. Correlations are drawn between the experimental parameters and the reported coefficients. Different materials are examined and categorized according to reported recombination coefficients into catalytic, semi-catalytic, and inert materials. Measurements from the literature of the recombination coefficients for some materials are compiled and compared, along with the possible system pressure and material surface temperature dependence of the materials' recombination coefficient. A large scattering of results reported by different authors is discussed, and possible explanations are provided.
对科学文献中可获取的关于中性氧原子在各种材料上的非均匀表面复合的相关数据进行了综述和讨论。通过将样品置于非平衡氧等离子体或其余辉中来确定系数。对用于确定系数的实验方法进行了研究，并将其分类为量热法、光化学测定法、NO滴定法、激光诱导荧光法以及各种其他方法及其组合。还研究了一些用于确定复合系数的数值模型。得出了实验参数与报道的系数之间的相关性。根据报道的复合系数，对不同材料进行了检查，并将其分类为催化材料、半催化材料和惰性材料。整理并比较了文献中一些材料的复合系数测量值，以及材料复合系数可能对系统压力和材料表面温度的依赖性。讨论了不同作者报道结果的较大分散性，并给出了可能的解释。
