Novel S-Scheme Loofah Biochar/Mos2/G-C3n4 Heterojunctions with Efficient Photogenerated Carrier Separation and Transfer Capability: Effect, Mechanism and Application

Published: Jan. 1, 2025

The construction of S-scheme heterojunctions has drawn widespread attention within the photocatalysis field due to their capacity for efficient separation photogenerated carriers, leading excellent photo-oxidation-reduction performance. Herein, a novel loofah biochar/MoS2/g-C3N4 (LB/MS/CN) heterojunction was successfully constructed by ultrasonication in 50% ethyl alcohol and heat treatment N2 atmosphere. Degradation experiments showed that 5% LB/MS/CN ternary photocatalyst had optimal photocatalytic efficiency (96.4%) degradation rhodamine B (RhB), reaction rate (k) this (0.05420 min-1) 5.4 times unmodified CN (0.01001 min-1). Ultraviolet-visible diffuse reflectance spectra, Mott-Schottky, free radical trapping suggested carriers were transferred through structure. Consequently, co-catalytic action LB synergistic impact structure between MS led reduced carrier recombination rate. Furthermore, outstanding stability maintain RhB performance under various environmental conditions (H2PO4-, NO3-, SO42-, HCO3-, NaCl, HA, real water), showing good promise practical applications. Thus, work provides possible strategy purifying wastewater visible light.

Synergistic Engineering of Energy Band Alignment and Interfacial Electric Field Distribution over Bi-bismuth-Based Hetero-nanofibers for Boosting Visible-Light-Driven Photocatalytic Ammonia Synthesis and Antibiotic Removal

Langmuir, Journal Year: 2024, Volume and Issue: 40(21), P. 11263 - 11276

Published: May 14, 2024

Synergistic engineering of energy band alignment and interfacial electric field distribution is essential for photocatalyst design but still challenging because the limitation on refined regulation in nanoscale. This study addresses issue by employing surface modification thermal-induced phase transformation Bi2MoO6/BixOyIz hetero-nanofiber frameworks. The switches from a type-II interface to Z-scheme contact with stronger redox potentials inhibited electron traps, optimized built-in could be reached based experimental theoretical investigations. engineered hetero-nanofibers exhibit outstanding visible-light-driven photocatalytic nitrogen reduction activity (605 μmol/g/h) tetracycline hydrochloride removal rate (81.5% within 30 min), ranking them among top-performing bismuth series materials. Furthermore, photocatalysts show promise activating advanced oxidants efficient organic pollutant degradation. Moreover, Bi2MoO6/Bi5O7I possess good recycling stability owing their three-dimensional network structure. research offers valuable insights into heterojunction environmental remediation industrial applications.
