In situ formic acid dehydrogenation observation using a UV-vis-diffuse-reflectance spectroscopy system

By applying a simple method on the generated gas concentration in the center of a round cell through high-speed stirring, we succeeded in continuously monitoring catalytic formic acid dehydrogenation using a newly developed in situ/operando UV-vis-diffuse-reflectance spectroscopy system, which can exhibit a high S/N ratio and reliable spectra without any mechanical errors from gas meters.
