Special Issue Information

Dear Colleagues,

Photocatalytic degradation and hydrogen production has been developed over decades and is considered a green and advanced technology in the environmental and energy fields. Now, efficient visible light absorption and the rapid separation of photogenerated electron–hole are the main factors to improve their photocatalytic efficiency. Therefore, the generation, transfer, and reaction of the photogenerated carries has become the core content of photocatalytic research. In general, photogenerated electrons and holes can be modulated by controlling composition, morphology, surface defects, surface coordination environment, and composite catalysts.

This Special Issue of Nanomaterials aims to delve deeper into the mechanisms and processes of photocatalytic degradation and hydrogen production. This field has developed rapidly in the past 20 years and has attracted the attention of a large number of researchers. The relation between the surface properties of photocatalysts and their catalytic performance is of particular interest. For this Special Issue, we invite the contributions of the leadership group in this field, with the aim of balancing the latest developments in the discipline.

The visible-light-driven photocatalytic degradation of pharmaceutical pollutants in aquatic environments is a promising strategy for addressing water pollution problems. This work highlights the use of bromine-ion-doped layered Aurivillius oxide, Bi2WO6, to synergistically optimize the morphology and increase the formation of active sites on the photocatalyst’s surface. The layered Bi2WO6 nanoplates were synthesized by a facile hydrothermal reaction in which bromine (Br−) ions were introduced by adding cetyltrimethylammonium bromide (CTAB)/tetrabutylammonium bromide (TBAB)/potassium bromide (KBr). The as-synthesized Bi2WO6 nanoplates displayed higher photocatalytic tetracycline degradation activity (~83.5%) than the Bi2WO6 microspheres (~48.2%), which were obtained without the addition of Br precursors in the reaction medium. The presence of Br− was verified experimentally, and the newly formed Bi2WO6 developed as nanoplates where the adsorbed Br− ions restricted the multilayer stacking. Considering the significant morphology change, increased specific surface area, and enhanced photocatalytic performance, using a synthesis approach mediated by Br− ions to design layered photocatalysts is expected to be a promising system for advancing water remediation.
