Enhanced photocatalytic activity of surface disorder-engineered CaTiO 3

Fabrication of novel AgBr/Bi24O31Br10composites with excellent photocatalytic performance

“…1,2 Over the past decade, TiO 2 and ZnO have received tremendous attention owing to their advantages of nontoxic nature, low cost, high photosensitivity, and eco-friendly features in the eld of photocatalytic applications. 3,4 Unfortunately, the wide band gap photocatalysts can only absorb photons in the ultraviolet (UV) range, and thus their photocatalytic activity is limited under irradiation of solar light as it contains only 5% UV light. 5,6 To achieve efficient use of solar energy, it is urgent to explore and develop new types of visible-light-responsive photocatalysts.…”

Construction of Z-Scheme g-C3N4/CNT/Bi2Fe4O9 Composites with Improved Simulated-Sunlight Photocatalytic Activity for the Dye Degradation

“…It can be seen that all samples exhibit a typical semicircle shape. Generally, the radius of the semicircle is related to charge-transfer resistance at the electrode–electrolyte interface [63]. Among these samples, 8%g-C 3 N 4 /1.5%CNT/BFO exhibits the smallest semicircle radius, suggesting that the ternary composite possesses the lowest charge-transfer resistance and the fastest photogenerated charge migration across the interface.…”

Tunable Graphene-based Plasmonic Perfect Metamaterial Absorber in the THz Region

“…However, if we want to continue to develop terahertz (THz) technology, we need to solve a difficult problem: finding a kind of material that can strongly respond to the terahertz band. Metamaterials are the best choice available to solve this problem [12]. Because the high absorption of light is of great significance to optical detectors and photovoltaic power generation, the high absorptivity of light, even perfect absorption, has attracted great attention.…”
