One-dimensional nanostructure based materials for versatile photocatalytic applications

Abstract

One-dimensional (1D) nanostructures are believed to play a significant role on the horizon of material science, and are a promising class of ideal high performance candidates for energy storage and conversion owing to their unique optical, structural and electronic properties. In particular, 1D nanostructure-based photocatalysts have been attracting ever-growing research attention. In this review article, we mainly focus on systematically summarizing the applications of 1D-based nanocomposites in photocatalysis, including nonselective processes for the degradation of pollutants, direct solar energy conversion to storable fuels and selective transformations for organic synthesis. Particularly, we explore the new directions for boosting the photocatalytic performances of 1D nanostructures, including graphene-1D nanocomposites, surface modification, 1D core-shell nanostructures and different exposed facet effects. It is hoped that this article will promote the efficient harnessing and rational development of the outstanding structural and electronic properties of 1D nanostructures to design more efficient 1D-based photocatalysts towards numerous applications in the field of solar energy conversion.

Photocatalytic conversion of CO2 into value-added and renewable fuels

“…low photoconversion efficiency. In order to develop efficient photocatalysts or systems for artificial photosynthetic of CO 2 , approaches in terms of light harvesting and photogenerated charge carriers boosting have been attempted [35][36][37][38][39][40][41][42][43]. On the other hand, photocatalytic reduction of CO 2 is quite challenging since it involves not only carbon reduction, but also proton transfer and hydrogenation [22,30,31].…”

Facile Synthesis of Highly Efficient One-Dimensional Plasmonic Photocatalysts through Ag@Cu2O Core–Shell Heteronanowires

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] An important application of 1D nanostructures is in photocatalytic degradation of organic pollutants, and recent decades have witnessed an exponential growth in the design and fabrication of highly efficient and active photocatalysts due to the growing awareness of environmental pollution issues and safety considerations. Various semiconducting nano-photocatalysts, especially metal oxide semiconductors such as TiO 2 and ZnO, are being extensively investigated.…”

g-C3N4-Based Nanomaterials for Visible Light-Driven Photocatalysis

“…In recent years, 1D nanostructures have attracted interest as photocatalysts due to their unique morphology and photophysical properties [66,67], and hence there is interest in preparing 1D g-C 3 N 4 . 1D g-C 3 N 4 nanorods with different aspect ratios were prepared by the reflux of g-C 3 N 4 nanoplates as a function of solvent and reflux time [68].…”
