SPR effect of bismuth enhanced visible photoreactivity of Bi2WO6 for NO abatement

Structural engineering of 3D hierarchical Cd0.8Zn0.2S for selective photocatalytic CO2 reduction

“…Thus, the fabrication of photocatalysts with sufficient CO2 adsorption and charge-transfer capabilities is needed [15][16][17][18]. So far, a relatively new effort of designing desirable morphologies and architectures benefits solar-harvesting and CO2 absorption, leading to increased active sites and potential interface functionalities [19,20]. For instance, Liu et al [21] prepared ultrathin 2D covalent organic framework nanosheets with excellent CO production due to a large surface area and enhanced contact between the substrate and the molecule.…”

Cu–Ag alloy for engineering properties and applications based on the LSPR of metal nanoparticles

“…On the other hand, the near-eld enhancement can signicantly improve the absorption efficiency of adjacent semiconductor with proper bandgap. 14 Theoretically, the non-radiative decay of LSPR can take place through four channels: 15 (1) inter-band electron transition; (2) surface-assisted electron transition; (3) phonon-assisted electron transition; (4) the classical resistive loss. Among them, the inter-band electron transition contributes mostly to the generation of hot carriers, and the resistive loss, which originates from the intra-band transitions of conduction electrons, mainly generates heat and competes with the other channels.…”

Recent progress in Bi2WO6‐Based photocatalysts for clean energy and environmental remediation: Competitiveness, challenges, and future perspectives

“…The deposition of metallic nanoparticles has been demonstrated as an effective method to suppress photogenerated charge carrier recombination due to the functions of metallic nanoparticles, namely, the Schottky barrier and surface plasmon resonance (SPR) excitation. [ 118 ] For instance, the photogenerated electrons can transfer directly from Bi 2 WO 6 to metal, thus efficiently suppress the charge recombination. [ 119 ] Metal Ag can be sufficiently deposited on Bi 2 WO 6 .…”

“…Additionally, we deeply illustrate and analyze the connections between the morphological, photophysics and photochemical properties of Bi 2 WO 6 , which include dopant or defect structures, metal deposition techniques, semiconductor combinations and surface modification by carbon‐based materials with conjugated π‐structures. [ 39–181 ] We critically review the practical applications of water splitting, pollutant removal, and especially CO 2 reduction. These aspects reflect the research status of Bi 2 WO 6 , as well as its potential and opportunities in the field of clean energy and environmental protection.…”
