WebBPEI (40 mg, 50 wt % in water) was dried overnight in a vacuum. Then, 20 mg of the dried polymer backbone was dissolved in dry dimethyl sulfoxide (DMSO) (1.3 mL) under an Ar atmosphere and fresh Ar-saturated Et 3 N (12 μL) was added. The solution was stirred for 5 min. Three vacuum-Ar cycles were carried out to ensure completely O 2-free Web28 feb 2024 · However, in Ar-saturated HCOONa solution, the one-dimensional structure could be maintained and reconstructed into rough porous bismuth nanowires (Bi NWs). …

Web28 feb 2024 · However, in Ar-saturated HCOONa solution, the one-dimensional structure could be maintained and reconstructed into rough porous bismuth nanowires (Bi NWs). Bi NWs showed less stability during ECR, which also generated surface amorphous oxide layer and further fragmentated into nanoparticles or nanosheets. Web20 lug 2024 · The CV curves were measured at 100 mV/s between 0.5 and 0.7 V RHE in Ar-saturated 0.5 M H 2 SO 4 at 25°C.
