We present a dedicated end-station for solution phase high repetition rate (MHz) picosecond hard x-ray spectroscopy at beamline 15-2 of the Stanford Synchrotron Radiation Lightsource. A high-power ultrafast ytterbium-doped fiber laser is used to photoexcite samples 640 kHz, while data acquisition operates 1.28 MHz storage ring recording in an alternating on-off mode. The time-resolved measurements are enabled via gating detectors with 20 mA/70 ps camshaft bunch SPEAR3, mode available during...
Photocatalysis is a promising concept for the direct conversion of solar energy into fuels and chemicals. The design, experimental protocol, performance multimodal versatile flow reactor characterization powdered immobilized photocatalysts are herein presented. Ultimately, this instrument enables rigorous evaluation photocatalysis metrics. apparatus quantifies transient gas-phase reaction products via online real-time gas analyzer mass spectrometry (RTGA-MS). For H2, most challenging gas,...
