This critical review describes the reactivity of heterogeneous catalysts from the point of view of four simple, but essential for Chemistry, molecules (namely dihydrogen, carbon monoxide, nitrogen monoxide and ethylene) that are considered as probes or as reactants in combination with "in situ" controlled temperature and pressure Infrared spectroscopy. The fundamental properties of H(2), CO, NO and C(2)H(4) are shortly described in order to justify their different behaviour in respect of isolated sites in different environments, extended surfaces, clusters, crystalline or amorphous materials. The description is given by considering some "key studies" and trying to evidence similarities and differences among surfaces and probes (572 references).
这篇评论性文章从四个简单但对化学至关重要的分子（即氢气、一氧化碳、一氧化氮和乙烯）的角度描述了多相催化剂的反应性，这些分子被认为是探针或反应物，与“原位”控制温度和压力的红外光谱法结合使用。简要描述了 H(2)、CO、NO 和 C(2)H(4) 的基本性质，以解释它们在不同环境中的孤立位、扩展表面、团簇、结晶或无定形材料中的不同行为。通过考虑一些“关键研究”，并试图证明表面和探针之间的相似性和差异性，给出了描述（572 篇参考文献）。
