Temperature Programmed Reduction (TPR) with quadrupole mass spectrometry (MS) addresses a long-standing challenge in catalyst characterisation: the inability to distinguish between hydrogen consumption mechanisms during reduction. Conventional temperature programmed reduction reveals when a material responds to hydrogen, but rarely explains how or why that response occurs. If quadrupole MS is ...
Materials often owe their performance to subtle differences between surface sites, yet these variations are not always easy to distinguish experimentally. As temperature changes, molecules bound to a surface respond in ways that reflect how and where they are attached. Temperature programmed desorption uses controlled heating to trigger such responses in a systematic way. When evolved gas ...
Catalyst deactivation studies are central to maintaining efficiency in industrial chemical processes, including petroleum refining, petrochemical production, syngas and hydrogen manufacture, environmental catalysis for emissions control, and large-scale chemical synthesis such as ammonia and methanol production. Over time, catalysts lose activity due to carbon deposition, sulfur poisoning, and ...
