Electrochemical measurements in conjunction with in situ Raman analysis displayed that the MXene coating effectively prevented the structural deterioration and irreversible redox mechanism of PPy during the electrochemical analysis. The synthesized MXene@PPy composite when used as a flexible RAB device (Fig...
with high activity and stability was constructed by a simple method.Important insights for the design of heterophase electrocatalysts is proposed.In situ Raman reveals key phase transition to NiOOH at elevated potential.Fe etching increases oxygen vacancy and conductivity, thus increasing OER performance...
In this work, a facile and rapid route is reported to fabricate the Cr doped FeNi LDH nanosheet with ultra small scaled on situ modified stainless steel under ambient condition. Especially, the modified SS electrocatalysts exhibit outstanding OER activity, which achieves a Tafel slope of 44 mV de...
The Raman spectra of 16O-labelled samples were shown in black dash lines for comparison. Full size image In addition to the DEMS measurement, the quasi in-situ Raman spectra were also used to confirm the participation of lattice oxygen in OER. The samples were first activated in electrolyte ...
Earlier, Bell and co-workers [56] had proven that in the highly active Ni:Fe OECs, NiOOH was forming under OER conditions which were revealed through in situ Raman analysis in which they found two characteristic bands at 475 and 555 cm−1 that correspond to metal (Ni) hydroperoxide. ...
