Achieving Enhanced UV and Visible Light Photocatalytic Activity for Ternary Ag/AgBr/BiOIO₃: Decomposition for Diverse Industrial Contaminants with Distinct Mechanisms and Complete Mineralization Ability

Heterojunction fabrication and noble metal deposition serving as efficacious means for promoting photocatalytic activity attract huge interests. Here, a series of ternary Ag/AgBr/BiOIO₃ composite photocatalysts that integrate the above two aspects are prepared by in situ crystallization of Ag/AgBr on BiOIO₃. The photocatalytic performance is first investigated by degrading MO with visible light and UV light irradiation. The results indicate that Ag/AgBr/BiOIO₃ composites present strengthened photocatalytic activity compared with BiOIO₃ and Ag/AgBr under both light sources. Distinct activity enhancement levels corresponding to different mechanisms with UV and visible light illumination are uncovered, which are closely related to the applied light source. The universal catalytic activity of Ag/AgBr/BiOIO₃ is surveyed by decomposition of diverse antibiotics and phenols, including tetracycline hydrochloride, chlortetracycline hydrochloride, bisphenol A, phenol, and 2,4-dichlorophenol which discloses that this ternary heterojunction photocatalyst demonstrates unselective catalytic activity with universality. Importantly, Ag/AgBr/BiOIO₃ displays a strong mineralization ability, completely decomposing BPA into CO₂ and H₂O. This work affords a new reference for designing heterojunction photocatalyst with multiple advantageous effect and powerful capability for environmental purification

Transcriptome Analysis of Thermal Parthenogenesis of the Domesticated Silkworm

<div><p>Thermal induction of parthenogenesis (also known as thermal parthenogenesis) in silkworms is an important technique that has been used in artificial insemination, expansion of hybridization, transgenesis and sericultural production; however, the exact mechanisms of this induction remain unclear. This study aimed to investigate the gene expression profile in silkworms undergoing thermal parthenogenesis using RNA-seq analysis. The transcriptome profiles indicated that in non-induced and induced eggs, the numbers of differentially expressed genes (DEGs) for the parthenogenetic line (PL) and amphigenetic line (AL) were 538 and 545, respectively, as determined by fold-change ≥ 2. Gene ontology (GO) analysis showed that DEGs between two lines were mainly involved in reproduction, formation of chorion, female gamete generation and cell development pathways. Upregulation of many chorion genes in AL suggests that the maturation rate of AL eggs was slower than PL eggs. Some DEGs related to reactive oxygen species removal, DNA repair and heat shock response were differentially expressed between the two lines, such as <i>MPV-17</i>, <i>REV1</i> and <i>HSP68</i>. These results supported the view that a large fraction of genes are differentially expressed between PL and AL, which offers a new approach to identifying the molecular mechanism of silkworm thermal parthenogenesis.</p></div

Easily and Synchronously Ameliorating Charge Separation and Band Energy Level in Porous g‑C₃N₄ for Boosting Photooxidation and Photoreduction Ability

Metal-free graphitic carbon nitride (g-C₃N₄) shows benign photocatalytic abilities concerning contaminant decomposition and hydrogen evolution under visible light irradiation. Developing facile modification tactics for promoted activity of g-C₃N₄ has always been desirable and worth pursuing. Herein, we report the integration of multiple (three-in-one) advantageous effects in g-C₃N₄ photocatalyst by a simple co-pyrolyzation of co-precursors melamine and NH₄HCO₃. This strategy utilizing NH₄HCO₃ as a bubble soft template not only endows g-C₃N₄ with porous structure with enhanced specific surface area, but also renders highly promoted separation and transfer of charge carriers and up-shifted conduction band. Given these benefits, the modified g-C₃N₄ unfolds remarkably improved photocatalytic performance toward RhB degradation, NO removal, and hydrogen evolution. Additionally, the exploration on active radicals has also corroborated the ameliorated band structure and illustrates the photocatalytic mechanism. Our present work may open up a new avenue for ameliorating the photocatalytic property of g-C₃N₄ and also further our understanding of design of high-performance photoelectric materials
