  "abstract": "Pressurized sample infusion (PSI) enables real-time electrospray ionization mass spectrometric (ESI-MS) monitoring of reactions through continuous delivery of solution from a pressurized vessel. Existing PSI configurations, however, are not well suited to systems involving heterogeneous catalysts with strict geometric demands, such as TiO₂ nanotube plates. Here, we describe a modified PSI configuration in which a standard media bottle fitted with a silicone septum replaces a multineck Schlenk flask. This design accommodates plate-based catalysts that cannot be easily used in conventional PSI reactors (in this specific case, TiO₂ nanotube arrays), enables controlled pressurization via needle-based gas injection, and permits insertion of capillary tubing for continuous sample infusion to the mass spectrometer. Rhodamine B was used as a model compound to monitor photocatalytic (PC) and photoelectrocatalytic (PEC) degradation under different reaction conditions. The approach enables straightforward real-time mass spectrometric monitoring of PEC and PC systems employing heterogeneous catalysts.",
