Fluorinated-TiO₂/Mn_0.2Cd_0.8S S-Scheme Heterojunction with Rich Sulfur Vacancies for Photocatalytic Hydrogen Production

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(7), P. 7978 - 7988

Published: March 29, 2024

The quick recombination of photogenerated carriers and the high surface reaction barrier are two important aspects influencing photocatalytic hydrogen generation. In this paper, a sulfur vacancy-modified two-dimensional (2D) fluorinated-TiO2 nanosheet/Mn0.2Cd0.8S (F-TiO2/MCS) S-scheme heterojunction was synthesized by simple hydrothermal method to accelerate electron transfer. formation an between MCS nanoflowers 2D F-TiO2 enhances efficacy generation facilitating separation electron–hole pairs. Meanwhile, vacancies F-TiO2/MCS change local electronic structure capturing electrons, resulting in evolution rate for 3197 μmol g–1 h–1, which is 4.42 times greater than that pure MCS. Experimental measurements density functional theory (DFT) calculations show mutual synergy not only provides abundant H2 adsorption active sites but also promotes interfacial charge migration, improves performance composite. This work holds significance production heterojunctions.

Published: Nov. 3, 2023

Abstract Photocatalytic ammonia synthesis technology is one of the important methods to achieve green synthesis. Herein, two samples Cu ion‐doped W 18 O 49 with different morphologies, ultra‐thin nanowires (Cu‐W ‐x UTNW) and sea urchin‐like microspheres SUMS), are synthesized by a simple solvothermal method. Subsequently, 2 O‐W UTNW/SUMS in situ reduction, where NH 3 production rate ‐30 UTNW 252.4 µmol g −1 h without sacrificial reagents, which 11.8 times higher than that pristine UTNW. The sample rich oxygen vacancies, promotes chemisorption activation N molecules makes N≡N bond easier dissociate proton coupling. In addition, reduction‐generated nanoparticles exhibit ideal S‐scheme heterojunctions UTNW, enhances internal electric field strength improves separation transfer efficiency photogenerated carriers. Therefore, this study provides new idea for design efficient nitrogen fixation photocatalysis.
