Abstract

Harnessing photocatalysts to facilitate the visible-light-driven breakdown of water molecules is esteemed as a highly auspicious and ecologically sustainable approach for hydrogen production. This study aimed to improve the hydrogen production performance of single ZnO photocatalysts by preparing efficient Bi2Te3/ZnO and Bi2Se3/ZnO composite photocatalysts by microwave method. During the synthesis process, both Bi2Te3 and Bi2Se3 were fully fused and reacted with ZnO to form heterojunctions using magnetic stirring and microwave heating. The experimental results indicate a significant enhancement in the hydrogen production activity of the BT-Z and BS-Z composite photocatalysts. When the Bi2Te3 content is 5%, with a microwave temperature maintained at 135 °C and a microwave time of 90 min, the hydrogen production rate reaches 664.286 μmol∙h−1∙g−1 within 4 hr. On the other hand, when the Bi2Se3 content is 5%, with a microwave temperature maintained at 135 °C and a microwave time of 90 min, the hydrogen production rate reaches 515.306 μmol∙h−1∙g−1 within 4 hr.

Abstract

The offshore crude oil spill has caused serious environmental damage and affected the balance of the ecosystem. Due to the high viscosity and poor fluidity of crude oil, conventional adsorbents cannot effectively remove it. The heat converted from solar energy can reduce the viscosity of the crude oil, improved its fluidity, allowing it to be adsorbed by a porous material and then recycle, it is considered an effective approach. Herein, we have designed a melamine composite sponge decorated with Fe3O4 and modified by PDMS (MS@Fe3O4-PDMS) with good photothermal conversion performance, which can recover viscous crude oil with the assistance of solar energy. The surface temperature of MS@Fe3O4-PDMS can reach around 88.0 ℃ under the light intensity of 1 kW·m− 2, effectively heating crude oil and accelerating its absorption. In the continuous crude oil recovery experiment, the absorption rate of MS@Fe3O4-PDMS reached 52.46 kg·m− 2·h− 1. In addition, the composite sponge has good processability, facile preparation method, and practical application potential. [ABSTRACT FROM AUTHOR]
