Synthesis, structure and optical properties of (H2DMAPA)BiBr5, (H2DMAPA)BiBr2I3, (H2DMAPA)2AgBiBr8 and (H2EP)2AgBiBr8 lead-free perovskites

Seeking environmentally friendly halide perovskite photocatalysts: synthesis, structure and photocatalytic performance exploration

“…Finally, we characterized the photocatalytic performance of four hybrid HPs previously reported in our group: (H 2 DMAPA) BiBr 5 ( Q1 ), (H 2 DMAPA)BiBr 2 I 3 ( Q2 ), (H 2 DMAPA) 2 AgBiBr 8 ( Q3 ) and (H 2 EP) 2 AgBiBr 8 ( Q4 ). 51 Fig. 7(a)–(d) show the UV-vis absorption spectra at different irradiation time periods using Q1–Q4 as the catalysts, which show that they also have excellent degradation performance on Sudan III.…”

The effect of precursor concentrations on the structure and optoelectronic properties of quasi low-dimensional hybrid 2-methylpyridinium lead bromide crystalline phases

“…Keeping in mind the structure–property relationship, this approach paves the way to the design of materials that are interesting from both fundamental research and industrial applications perspectives. They can be formed from numerous organic 4,9,21–24 and inorganic 21,25,26 cations, halide anions, and their mixtures, 21,27–29 leading to technologically promising optical, 21,30 physico-chemical, 31 and electrical 10,30 properties. The structure–property relationship is most prominent in the case of quasi low-dimensional hybrid organometal halides with aromatic organic cations.…”
