Bi₂S₃–In₂S₃ Heterostructures for Efficient Photoreduction of Highly Toxic Cr⁶⁺ Enabled by Facet‐Coupling and Z‐Scheme Structure

Abstract

environment, which is defined as one of most toxic pollutants by the United States Environmental Protection Agency due to its high solubility. [1][2][3] With 100 times higher toxicity than Cr 3+ , Cr 6+ poses a great threat to the ecosystem, particularly from its biological recycling. [4] Thus the concentration of Cr 6+ in industrial wastewater needs to be strictly controlled before it can be safely discharged.

An indium-induced-synthesis In0.17Ru0.83O2 nanoribbon as highly active electrocatalyst for oxygen evolution in acidic media at high current densities above 400 mA cm−2

“…2c) is composed of In 3d 5/2 and In 3d 3/2 , which are located at 445.01 eV and 452.61 eV, respectively. 32 Compared with the corresponding peaks of pure In 2 O 3 (the detailed synthesis method is given in ESI,† and the XRD pattern of pure In 2 O 3 is given in Fig. S7†), In 3d 5/2 and In 3d 3/2 of In 0.17 Ru 0.83 O 2 -350 are positively shifted by about 0.6 eV.…”

“…Moreover, an appropriate band structure for semiconductors can effectively regulate the electronic structure of the reactive site. 30–35 Herein, indium doping was adopted to regulate the d-band center of the metal active site to enhance catalytic capacity. Furthermore, the reduction of the work function increases the electron transfer capacity between the reactants and the catalyst surface, 36 which is also conducive to the electrocatalytic process.…”

Chromium Oxide‐modified Mesoporous Zirconium Dioxide: Efficient Heterogeneous Catalyst for the Synthesis of 5‐Hydroxymethylfurfural

“…Although Chromium-based catalysts showed great catalytic activity, [28] they were very harmful owing to Cr posed a great threat to the ecosystem, particularly from its biological recycling. [49] In our reaction system, the question of Cr leaching was tested in the fructose conversion. The Cr/ZrO 2 catalyst was firstly heated in water without fructose at 180 °C.…”

Metal–Organic Framework-Templated Synthesis of In2S3/CoSx Nanocages for Photocatalytic Removal of Antibiotics

“…In recent decades, metal sulfide semiconductors, such as MoS 2 , ZnIn 2 S 4 , In 2 S 3 , and so forth, have garnered significant research interest due to their unique properties and versatile applications. − Among these materials, In 2 S 3 has attracted considerable attention owing to its tunable energy band structure and photoelectrochemical properties. It exhibits strong photocatalytic activity in pollutant degradation, photocatalytic hydrogen evolution, carbon dioxide reduction, − and so forth.…”
