Ferroelectrics for photocatalysis

Performance of hydrogen evolution reaction of R3C ferroelectric ZnSnO3 nanowires

“…Therefore, many researchers are seeking more efficient catalysts to improve the water splitting into hydrogen and oxygen by a variety of technologies, including heterojunction nanostructures [3][4][5], co-catalysis and interface engineering [5][6][7][8][9]. Recently, the unique spontaneous polarization of ferroelectric materials has offered superior photoelectrochemical (PEC) properties [10], with the ferroelectric photocatalyst for enhancing hydrogen evolution reaction (HER) receiving much attention [10][11][12][13]. ZnSnO 3 has an eco-friendly polymorphous and good biocompatibility, with high electron mobility, unique optical properties [14] and catalytic activity [15].…”

Understanding the impact of Bi stoichiometry towards optimised BiFeO3 photocathodes: structure, morphology, defects and ferroelectricity

“…In this context, ferroelectric materials having spontaneous polarisation response have attracted much attention. 1 The domains inside ferroelectrics can be reversibly switched by external bias and an internal electric eld can remain due to the remnant polarisation aer removing the external electric eld, which favours the separation of photo-generated holes and electrons. 2,3 For this reason, employment of ferroelectric materials has been considered as an effective approach to improve photocatalytic activity.…”

“…Ferroelectric materials can also exhibit photocatalysis and pyrocatalysis along with piezocatalysis. 15,16 Hence, these materials can be claimed for multicatalysis applications. 12,17 Further, the synergetic effect of the catalysis mentioned above phenomena is also interesting.…”

“…This is still a less studied objective in most of the literature. Ferroelectric materials can also exhibit photocatalysis and pyrocatalysis along with piezocatalysis 15,16 . Hence, these materials can be claimed for multicatalysis applications 12,17 …”
