“…The pristine sample exhibited well‐crystallized spheres which were composed of a large amount of aggregated 50 nm sheets. This size and morphology of BWO are reasonable among literatures 4,9,11 . The combination of Co 3 O 4 did not change the original morphological structure, and the Co 3 O 4 obviously deposited on the surface of base BWO, indicating the hetero‐structure formed as reported in literatures 22,25,28,30 .…”

The combination of surface plasmon resonance (SPR) effect with hetero‐p–n structure shows promising benefits to optical linear and nonlinear properties. In this study, Au nanoparticles (NPs) decorated p–n hetero‐structured Co3O4/Bi2WO6 composite was synthesized and characterized in terms of the optical linear and nonlinear and magnetic properties, morphology, electron transition, charge transfer, energy band gap, polarizability, SPR effect, and oxygen vacancies using scanning electron microscopy, X‐ray photoelectron spectroscopy, electron paramagnetic resonance spectroscopy, Z‐scan, ultraviolet–visible spectra, and vibrating sample magnetometer. The combination of Co3O4 provided active 3d electrons transition and charge transfer which increased carriers’ concentration and reduced the energy band gap. Au SPR enhanced the internal polarization and strengthened the built‐in electric field, yielding strong nonlinear behavior. In addition, magnetic Co3O4 endowed sample with room‐temperature ferromagnetism which was obviously strengthened by Au NPs. The obtained sample is promising for laser and photonics applications.

“…[40,41] Recently, PMS was found that it could be activated by photogenerated e − /h + to produce SO 4 •− radicals. [42][43][44] But the degradation efficiency was increased to 98.57% in the Bi 2 MoO 6 /Vis/PMS system in an hour, which meant the degradation efficiency of activating PMS with Bi 2 MoO 6 under visible light irradiation was much better than the Bi 2 MoO 6 only irradiated by visible light. As shown in Figure 7, the degradation efficiency of Bi 2 MoO 6 /Vis/PMS system was also much higher than the other systems.…”

Bi 2 MoO 6 nanoflakes are synthesized via a normal hydrothermal method. Bi 2 MoO 6 photocatalysts show lower photocatalytic activity for the degradation of methylene blue under visible light irradiation. In order to further enhance the degradation efficiency, Bi 2 MoO 6 is used to activate the peroxymonosulfate for the degradation of methylene blue under visible light. Bi 2 MoO 6 nanoflakes show excellent degradation efficiency in the Bi 2 MoO 6 /Vis/peroxymonosulfate (PMS) system. Moreover, the influences of PMS dosage, pH value, and inorganic anions on photodegradation are evaluated. The mechanism of activating peroxymonosulfate is proved by radical quenching experiment, which reveals that sulfate radicals govern the removal of methylene blue.

Electrocatalytic water splitting shows great potential for producing clean and green hydrogen, but it is hindered by slow reaction kinetics. Advanced electrocatalysts are needed to lower the energy barriers. The establishment of built‐in electric fields (BIEF) in heterointerfaces has been found to be beneficial for speeding up electron transfer, increasing electrical conductivity, adjusting the local reaction environment, and optimizing the chemisorption energy with intermediates. Engineering and modifying the BIEF in heterojunctions offer significant opportunities to enhance the electronic properties of catalysts, thus improving reaction kinetics. This comprehensive review focuses on the latest advances in BIEF engineering in heterojunction catalysts for efficient water electrolysis. It highlights the fundamentals, engineering, modification, characterization, and application of BIEF in electrocatalytic water splitting. The review also discusses the challenges and future prospects of BIEF engineering. Overall, this review provides a thorough examination of BIEF engineering for the next generation of water electrolysis devices.
