“…Photocatalytic degradation is considered as an efficient way for the removal of dye contaminants from water [9]. Various research articles are published on the photocatalytic activity of pure BFO nanoparticles synthesized using different methods like hydrothermal [10,11], sol-gel [12,13], ultrasonic radiation [9], autocombustion [14] for degradation of rhodamine B (RhB), solvothermal [15] for degradation of methylene blue (MB), microwave-hydrothermal [16], co-precipitation [17] for degradation of methyl orange (MO) and hydrothermal [18] for degradation of congo red. There are only a few reports on the influence of dopant modified BFO on the photocatalytic degradation of organic dyes.…”

“…A number of solutions have recently been proposed to address the current problems of further developing photocatalyst using Earth‐abundant elements, including using multi‐ferroic materials such as BiFeO 3 or BaTiO 3 , a ferroelectric material that shows some remarkable photocatalytic performances. Both these, and indeed all ferroic (ferroelectric and piezoelectric) materials can exhibit an internal polarization field when at rest (in the case of a ferroelectric) or when undergoing dynamic strain (as in the case of a piezoelectric) material .…”

With limited global resources for many of the elements that are found in some of the most common renewable energy technologies, there is a growing need to use "Earth-abundant" elements as a long-term solution to growing energy demands. The dye-sensitized solar cell has the potential to produce low-cost renewable energy, with inexpensive production and most components using Earth-abundant elements. However, the most commonly used material for the cell counter electrode (CE) is platinum, an extremely expensive and rare element. A selection of the materials investigated as alternative CEs are discussed, including metal sulfides, oxides, carbides, and nitrides and carbon-based materials such as carbon nanotubes, graphene, and conductive polymers. As well as having the potential for lower cost, these materials can also produce more-efficient devices due to their high surface area and catalytic activity. Therefore, once issues such as stability have been studied in more detail and scale-up of production methods are considered, there is a very promising future for the replacement of Pt in DSSCs with lower-cost, Earth-abundant alternatives.

“…In addition to BTO, BiFeO 3 (BFO) has been studied as a photocatalyst or incorporated into a photovoltaic device [28][29][30][31]. BFO is an interesting, or frustrating material depending on your end application, that has been variously described in the literature as having a direct, indirect band gap with a band gap reported from 2 to 3 eV or as a p or indeed n-type [32] material.…”
