Recent Advances in Plasmonic Photocatalysis Based on TiO₂ and Noble Metal Nanoparticles for Energy Conversion, Environmental Remediation, and Organic Synthesis

Abstract

Scheme 1. Different strategies and concepts employed in the design and development of photocatalysts based on a semiconductor, such as TiO 2 , and plasmonic NPs.

Metal halide perovskites for photocatalysis applications

“…In this way, they will be more competitive in the market than P25 that has been put into practical use. 234,235 As for CO 2 reduction, in addition to nano-particle photocatalytic systems, attention should also be paid to building flexible PM photoelectrodes or photovoltaic systems. While ensuring the conversion rate and selectivity of CO 2 reduction, the system can also be made into a shape that is conducive to capturing CO 2 in the atmosphere and separating some reduction products by using their flexible characteristics.…”

Considering single-atom catalysts as photocatalysts from synthesis to application

“…and metal sulfides (CdS, MoS 2 , etc. ) are widely studied as the photocatalysts ( Kumar et al., 2021 ; Kusiak-Nejman et al., 2021 ; Premaratne et al., 2004 ). As discussed in section atomic layer deposition method , by creating defect sites (i.e., O-defect, S-defect), the metal-oxides- and metal-sulfides-based SAPs can be easily synthesized by the atom trapping methods.…”

Porous Copper Foam‐Based Plasmonic Nanocrystals Modified 3D Semiconductor Nanoflowers for Multifold, Recyclable, and Portable Detection of Environmental Contaminant

“…[30,31] It is known that the building of semiconductor (TiO 2 ) and precious metal com posites is an effective method to modify the charge transfer kinetics of semiconductors. [32][33][34] Our previous work reported that AgTiO 2 core-shell nanostructures exhibited much higher photocatalytic activity than bare TiO 2 films because of the efficient carrier transfer at the AgTiO 2 interface by exposure ultraviolet light. [35] Zhang et al fabricated a mixed phase of anatase/rutile TiO 2 by a twostep hydrothermal method then deposited plasmonic Ag nanoparticles on the heterostructure surface to construct the anatase/rutile TiO 2 Ag hybrids.…”
