Poly(ionic liquid)‐Mediated Morphogenesis of Bismuth Sulfide with a Tunable Band Gap and Enhanced Electrocatalytic Properties

Abstract: Conventional polymer additives have a substantial impact on synthetic inorganic chemistry, but critical shortcomings remain; for example, low solubility in organic solvents and potential thermodynamic aggregates. Poly(ionic liquid)s have now been used as efficient additives that enable a high level control of bismuth sulfide crystals with significant size and morphological diversities. The bismuth sulfides exhibit tunable band structure as a result of the quantum size effects. Moreover, poly(ionic liquid)s are… Show more

“…For BS–BO, the peaks with a binding energy of 162.8 and 157.6 eV are correlated with Bi 4f 7/2 and Bi 4f 5/2 in Bi 2 S 3 , respectively. Moreover, the Bi 4f 7/2 and Bi 4f 5/2 peaks for Bi 2 O 3 shift toward higher energies by approximately 0.5 eV, which is because of the coupling effect resulted from the strong chemical bonding between Bi 2 O 3 and Bi 2 S 3 . The peak centered at 160.4 eV in BS–BO is ascribed to S 2p transition, which further confirms the formation of BS–BO heterostructures.…”

In addition, the high-resolution C 1s (Figure S2a) and O 1s (Figure S2b) XPS spectra of BS−BO indicate the presence of absorbed species, such as CTAB and H 2 O, which are consistent with the FTIR results.…”

“…22−25 Especially, they can be taken as the efficient solvent for the preparation of novel structured nanomaterials. Gao et al 26 synthesized a series of bismuth sulfides with different morphologies by using poly(ionic liquid)s as additives. Zhang and co-workers 27 have successfully fabricated the porous nitrogen-doped carbon materials by using poly(ionic liquid)s and sugars as precursors.…”

“…The rapid development of non-noble-metal catalysts that are abundant, active, and stable has promised to eliminate noble metals to reduce costs. These impressive low-cost materials include heteroatom-doped nanocarbons, transition metal oxides, , chalcogenide , and phosphide nanostructures, transition metal complexes, and biomimetic catalysts. In particular, researchers are making progress in revealing the structures of catalytic active sites of different catalysts, for example, perovskite oxide and molybdenum disulfide (MoS 2 ), thus offering inspiration for designs of new catalytic material systems. Significant advances in non-noble-metal catalyst development has been the topic of many excellent reviews, ,,, perspectives, , and book chapters …”

“…Besides catalysts described above, nanostructured inorganic minerals, including pyrites, molybdenites, , bismuthinite, pentlandite, and others, , were recently observed to advance the non-noble-metal catalyst community. These minerals exhibit versatile chemistry; some of them possess surface structures strongly similar to the active metal centers of natural enzymes (e.g., nitrogenase and hydrogenase), thus enabling intriguing catalytic performances. ,, Development opportunities seem to be particularly promising for pyrite-structured materials, because they could be made at nanoscale , and because of their diverse properties .…”
