Yolk–shell nanostructures: synthesis, photocatalysis and interfacial charge dynamics

Abstract

This review gives a comprehensive retrospection on the preparation and photocatalytic applications of yolk–shell nanostructures with additional focus on the realization of interfacial charge dynamics.

Intriguing electronic, optical and photocatalytic performance of BSe, M2CO2monolayers and BSe–M2CO2(M = Ti, Zr, Hf) van der Waals heterostructures

“…All these ndings demonstrate that the BSe-M 2 CO 2 heterostructures can be considered as potential photocatalysts for water splitting and provide theoretical guidance for designing high-performance nano-electronic and optoelectronic devices based on the BSe-M 2 CO 2 heterostructures.

Highly efficient visible light active Cu–ZnO/S-g-C3N4 nanocomposites for efficient photocatalytic degradation of organic pollutants

“…As cited in the previous literature, the doped transition metal assists the transfer of charge between ZnO and g-C 3 N 4 in CZS NCs. 49 Thus, in the CZS-25 nanocomposites, the photo-excited electrons were effectively conducted and used up in ROS production. Thus, the degree of e–h pairs recombination in CZ-25 is repressed, and its photocatalytic activity is improved.…”

Physical and photocatalytic properties of sprayed Dy doped ZnO thin films under sunlight irradiation for degrading methylene blue

“… 28 Since solar energy is a sustainable energy source, the use of photocatalytic nanomaterials is a promising technology for industrial wastewater treatments as dye degradation. 29 However, several parameters as light intensity, environmental temperature, or pH of the medium can impact significantly the efficiency of the photocatalysis processes. 30 Therefore, photocatalysts should ideally gather several properties such as long-term stability under variable operational conditions, specificity towards the water pollutants, and high absorption coefficient to optimize the solar spectrum harvesting.…”
