Controllable self-assembly of a novel Bi₂MoO₆-based hybrid photocatalyst: excellent photocatalytic activity under UV, visible and near-infrared irradiation

Abstract

Herein, using a simple one-step method, a Bi2MoO6-based photocatalyst with novel ultrathin nanohollow structure and simultaneous sub-10 nm Bi nanoparticles and sub-1 nm graphitic nitrogen-doped carbon nanodot (NCD) modification were successfully obtained. The coordination impact of the novel structure, SPR effect of Bi nanoparticles, up-conversion performance of graphitic NCDs and cooperative electronic capture properties of Bi metal and NCDs make the hybrid simultaneously exhibit fast charge separation and broad spectrum photocatalytic activity under UV, visible and near-infrared irradiation, leading to excellent photooxidation and photoreduction performance.

Surface‐Engineered Black Niobium Oxide@Graphene Nanosheets for High‐Performance Sodium‐/Potassium‐Ion Full Batteries

“…The black Nb 2 O 5− x @rGO nanosheets' electrode also shows a stabling discharge capacity of 81 mAh g −1 with almost no degradation after 3500 cycles at 1500 mA g −1 (Figure e). Compared to recently reported K‐ion anodes, such as graphite, soft carbon, CoSe 2 /carbon composite, CoS quantum dot nanoclusters, K 2 Ti 8 O 17 nanorod clusters, and MXene‐derived TiO 2 nanoribbons, the black Nb 2 O 5− x @rGO nanosheets' electrode demonstrates superiority of specific capacity, rate performance, and/or cycling performance, indicating its potential applications in PIBs.…”

Visible‐to‐NIR Photon Harvesting: Progressive Engineering of Catalysts for Solar‐Powered Environmental Purification and Fuel Production

“…Consequently, the CNDs/Cu 2 O composites show high photocatalytic activities under NIR light irradiation. Dong and co‐workers have constructed a N‐doped carbon dots (NCDs)/Bi‐Bi 2 MoO 6 photocatalyst for the capture of NIR light to enhance the photocatalytic activity . The NCDs can achieve an upconversion of light from 705–862 nm to a shorter wavelength of 350–500 nm.…”

Facile synthesis of a novel WO3/Ag2MoO4 particles-on-plate staggered type II heterojunction with improved visible-light photocatalytic activity in removing environmental pollutants

“…Generally, a weaker intensity of the PL emission spectra represents a lower charge recombination rate. 51 As shown in Fig. 10C, 10% Ag-W heterojunction display the lowest intensity under the excitation of light at l ¼ 325 nm, further indicating the vital role in the suppression of the recombination of photogenerated charge carriers.…”
