A series of studies with sets of analogous samples was carried out to show how the technique of methanol adsorption and desorption can be used to provide useful technical information in an industrial setting. Thermal desorption of methanol and its surface reaction products (formaldehyde, dimethyl ether, CO₂) offered data which could inform on the surface and even on the catalytic performance of the materials in selective oxidations such as the oxidation of isobutyraldehyde to methacrolein and of methanol to formaldehyde, although CO₂ desorption profiles were less informative than the others. The first study showed how the TPD profiles change with basicity (potassium doping) on bismuth molybdate; the second showed how potassium doping affects the desorption in the presence of redox promoters (Fe, Co), the third showed how the profiles change by doping with acidic promoters (V, P, Al) and the final one showed how the technique could be applied to understand a defect in an industrially manufactured product. This set of studies indicates that the use of methanol to study the surface of oxidic materials can provide insights that support the selection of catalyst candidates and help investigate reduced performance.

对一组类似样品进行了一系列研究，以展示如何使用甲醇吸附和解吸技术在工业环境中提供有用的技术信息。甲醇及其表面反应产物（甲醛、二甲醚、CO ₂）的热解吸提供了数据，这些数据可以告知材料在选择性氧化中的表面甚至催化性能，例如异丁醛氧化成异丁烯醛和甲醇氧化成甲基丙烯醛。甲醛，虽然 CO ₂解吸曲线比其他曲线提供的信息少。第一项研究显示了 TPD 曲线如何随钼酸铋的碱度（钾掺杂）而变化；第二个展示了在氧化还原促进剂（Fe、Co）存在的情况下钾掺杂如何影响解吸，第三个展示了通过掺杂酸性促进剂（V、P、Al）来改变分布图，最后一个展示了该技术如何用于了解工业制造产品中的缺陷。这组研究表明，使用甲醇研究氧化材料的表面可以提供支持选择催化剂候选物的见解，并有助于调查性能降低。
