Inorganic CsPbI3 perovskite solar cells (PSCs) owning comparable photovoltaic performance and enhanced thermal stability compared to organic-inorganic hybrid perovskites have attracted enormous interest in the past year. However, it is still a challenge stabilize desired black α-CsPbI3 ambient air for applications. Herein, sequential solvent engineering including addition of hydroiodic acid (HI) subsequent isopropanol (IPA) treatment fabricating stable working PSCs developed, novel...
A closely packed hybrid electrocatalyst Pt 1.5 Ni 1− x /Ni–N–C was engineered by a gas-promoted dealloying process, ensuring the relay catalysis of reaction intermediates at alloy and single sites, thus achieving high performance in PEMFCs.
Polybenzimidazole/graphite oxide (PBI/GO) and PBI/sulfonated graphite composite membranes were prepared for high temperature polymer electrolyte membrane fuel cells. The loaded with phosphoric acid to provide suitable proton conductivity. PBI/GO PBI/SGO characterized by XRD which showed that the d-spacing reflection (001) of SGO in PBI matrix was shifted from 2θ = 11°, meaning molecules intercalated into layers during preparation process. A low loading level reduced free avoided water loss...
Conductive hybrid carbon nanotube (CNT( films are prepared by a new and simple method. Thee graphite oxide nanoplatelet/carbon-nanotube exhibit an extremely low square resistance. The SEM image shows the surface morphology, reveals that one-dimensional nanotubes form conductive percolated network covering two-dimensional nanoplatelets.
Graphite oxide (GO)/Nafion composite membranes were prepared and used for polymer electrolyte membrane fuel cells (PEMFCs). Membranes characterized by transmission electron microscopy (TEM) scanning (SEM) which showed the distribution of graphite sheets in a Nafion matrix. Fourier transform infrared spectroscopy data (FTIR) GO vibrations at 3440 cm−1 was attributed to intermolecular hydrogen bonding 1724 ascribed CO stretching frequency. The proton conductivities (4 wt%)/Nafion composite,...
