Linking the enhanced deep NO oxidation of a ferroelectric K_0.5Bi_0.5TiO₃ nanowire photocatalyst to its spontaneous polarization and oxygen vacancies

Abstract

The fast recombination and slow transfer of photogenerated charge carriers impede the photo-oxidation process of NOx. Herein, the enhancement of charge separation over K0.5Bi0.5TiO3 with oxygen vacancies (KBT-O) is realized...

Utilization of Photocatalysis and Pyroelectric Catalysis to Enhance Catalytic Properties in Pb(Zr0.52Ti0.48) O3 Nanocubes: A Study on Pyro‐/photo‐bi‐catalysis Degradation of Dye Wastewater

“…[1][2][3] Many researchers have made outstanding achievements in solving the problem of resource and energy, [4][5][6][7] but the problem of environmental pollution is still the focus of research. [8][9][10] Upon this circumstance, it is urgent to find an efficient and simple method to degrade dye wastewater. Several traditional methods of degrading dye wastewater, such as adsorption, ultrafiltration, coagulation, have a lot of difficulties in complete decomposition, low cost and harmless disposal.…”

“…Especially water pollution, wastewater containing dyes is harmful to human beings, animals and plants [1–3] . Many researchers have made outstanding achievements in solving the problem of resource and energy, [4–7] but the problem of environmental pollution is still the focus of research [8–10] . Upon this circumstance, it is urgent to find an efficient and simple method to degrade dye wastewater.…”
