Lattice Distortion in Hollow Multi‐Shelled Structures for Efficient Visible‐Light CO₂Reduction with a SnS₂/SnO₂Junction

Abstract

Precise control of the micro‐/nanostructures of nanomaterials, such as hollow multi‐shelled structures (HoMSs), has shown its great advantages in various applications. Now, the crystal structure of building blocks of HoMSs are controlled by introducing the lattice distortion in HoMSs, for the first time. The lattice distortion located at the nanoscale interface of SnS2/SnO2 can provide additional active sites, which not only provide the catalytic activity under visible light but also improve the separation of photoexcited electron–hole pairs. Combined with the efficient light utilization, the natural advantage of HoMSs, a record catalytic activity was achieved in solid–gas system for CO2 reduction, with an excellent stability and 100 % CO selectivity without using any sensitizers or noble metals.

Heat Diffusion‐Induced Gradient Energy Level in Multishell Bisulfides for Highly Efficient Photocatalytic Hydrogen Production

“…[ 5,6,17 ] Among them, precisely designed hollow multishell structures possess attractive characteristics for photocatalysis, including efficient light harvesting, improved charge transfer, and high specific surface area. [ 17,21,27–32 ] Single/multishell hollow spheres, [ 18,33,34 ] hollow cubes, [ 35–37 ] egg yolk shells, [ 27,36,38 ] and other shaped hollow spheres have been reported. [ 19,28,39–41 ] In general, the preparation and synthesis of multishell structured photocatalysts can be divided into three methods according to the template used: hard templating, soft templating, and self‐templating method.…”

“…[ 18,21,33,46 ] The complex multishell hollow materials with heterogeneous structures are expected to provide unique properties and functions because they retain the advantages of a single component while offering synergetic effects between the different components. [ 28,29,35,43,47 ] However, the major synthetic obstacle comes from the difficulty in accurately controlling the formation of multiple shells at the nanoscale. [ 35,48 ] The precise synthesis of multishell nanostructures with two different compounds has remained yet an experimental challenge.…”

When hollow multishelled structures (HoMSs) meet metal–organic frameworks (MOFs)

“…[4][5][6][7][8] Aerwards, this breakthrough in synthetic methodology made HoMS a hotspot in material science, and various related applications have been rapidly developed. 7,[9][10][11][12][13][14] HoMS material has been widely recognized as one of the most promising functional materials. 15 However, the precise fabrication of HoMSs (with the composition of metal oxide/sulde/ phosphide, not the MOF-based HoMS, unless otherwise speci-ed) on the molecular level is still confronted with challenges.…”

POM‐Incorporated CoO Nanowires for Enhanced Photocatalytic Syngas Production from CO2

“…First the photocurrent responses were performed to investigate the charge-hole separation efficiency. [43] Figure 4 a shows that both kinds of UNWs exhibit distinct photocurrent response and display no obvious delay on external light/dark switch. As comparison, two kinds of NWBs exhibit obvious lag in photocurrent response.…”
