“…It is stemmed from the reduced hydrogen bonding interactions between -SO 3 À and H 2 O. The former one can be attributed to the rocking vibration of -COC-(A), 49 while the exact assignment of the latter one is still in controversy. For a hydrated Nafion membrane, H 2 O mainly exists in the hydrophilic (-SO 3 À ) n domains.…”

“…39 It is noteworthy that the dehydration process leads to the appearance of two new IR peaks at 915 cm À1 and 1415 cm À1 . The former one can be attributed to the rocking vibration of -COC-(A), 49 while the exact assignment of the latter one is still in controversy. 39,50 The unavoidable alkyl impurities in the original Nafion solution may contribute to the IR absorption here due to the bending vibrations of CH (1/2/3) .…”

“…Infrared (IR) spectroscopy, in particular, has proved to be a very powerful experimental technique to study in situ or operando electrocatalytic reactions on metal surfaces, and detect various adsorbed oxygenated species . However, thus far, most reports of in situ spectroscopic studies have been restricted to thin‐film metal surfaces, which cannot replicate features of nanoparticle catalysts, such as size dependence .…”

“…[13][14][15][16][17] A hydrated membrane is essential for fuel cell operation. Operando IR spectroscopy 7,[18][19][20][21][22][23][24][25][26][27] requires stringent control of reactant stream humidification, flow rate, and cell temperature to prevent condensed water from overwhelming the IR spectra. Raman micro-spectroscopy, which is tolerant of condensed water, is complementary to FTIR.…”
