Design and modification of perovskite materials for photocatalytic performance improvement

Research Progress on Photocatalytic CO2 Reduction Based on Perovskite Oxides

“…A perovskite oxide-based heterojunction with low-dimensional materials changes the bandgap, lowers the distance from charge to surface, increases the active sites, and suppresses charge recombination. [225] Low-dimensional materials can be divided into 2D (nanosheets), 1D (nanotubes, nanowires, nanofibers, and nanoribbons), and 0D (nanospheres, nanoparticles, and quantum dots (QDs)). Many of the heterojunctions mentioned above belong to low-dimensional materials and exhibit good photocatalytic reduction activity of CO 2 .…”

Enhanced photocatalytic hydrogen production performance of K0.5Na0.5NbO3-based ferroelectric semiconductor ceramics by Nd/Ni modification at A/B sites and polarization

“…Among them, perovskite materials of niobium oxides have shown exemplary performance in ferroelectric and piezoelectric properties, 1 photocatalytic degradation, 2 environmental remediation of wastewater, 3 hydrogen and oxygen generation, and carbon dioxide reduction. 4 In recent years, perovskite materials have received much attention in the field of PHE. Lili Li et al prepared CoO/KNbO 3 materials with excellent PHE properties by hydrothermal and calcination methods.…”

Photocatalytic degradation of ammonia nitrogen using a Z-type nano-TiO2/LaMnO3 heterojunction

“…The selection of a nano-TiO 2 composite with LaMnO 3 means they can complement each other's advantages and broaden the spectral response range, and the introduction of lanthanum manganate can reduce electron-hole compounding efficiency, accelerate migration and separation of photogenerated carriers, and improve the photocatalytic stability. Meanwhile, the doped nano-TiO 2 can solve the problems of low photocatalytic activity and low carrier separation efficiency of pure chalcogenides, [24][25][26] and the composite has a good application prospect in photocatalytic degradation of ammonia nitrogen in wastewater.…”
