Summary: Researchers used metagenomics and transcriptomics to study microbial dynamics in a 15-year old bioreactor with benzene as the main carbon source. Their findings revealed that most members of the microbial community likely feed on metabolic leftovers or necromass, while only a few are capable of degrading benzene. These benzene degraders are essential for maintaining species richness and ecosystem stability within the community.

Summary: The present study developed an impressive method to eliminate toxic nitro aromatic compounds using polyoxometalate-based composites. By integrating transition metal substituted polyoxometalates onto modified protonated graphitic carbon nitride, stable compounds were formed and used for the reduction of toxic compounds. The composite with copper substituted polyoxometalate showed the highest catalytic activity. This environmentally friendly process could be carried out in water at room temperature.

Summary: Aromatic compounds pose a threat to the environment and human health, and traditional physical and chemical methods for their treatment are criticized for causing secondary pollution and being expensive. Microalgae-based biodegradation approaches have emerged as a promising alternative due to their ecological security and carbon sequestration abilities. This study reviewed the degradation efficiency, pathways, metabolites, and influencing factors of aromatic compounds, such as BTEX, PAHs, and phenolic compounds, by microalgae. The integrated technologies based on microalgae for aromatic compound degradation were also discussed, along with the limitations and future research needs in this field.

Summary: This study systematically assessed the biotransformation of 4-Hydroxybenzoic acid (HBA) in a microbial electrolysis cell (MEC) for the production of renewable H-2. The findings showed that in the absence of nitrate, most HBA was converted to phenol, while under nitrate-reducing conditions, complete degradation of HBA to H-2 was achieved. The predominant bacteria involved in this process were Magnetospirillum and Geobacter, contributing to the successful bioelectrochemical conversion of HBA.

Summary: Converting corn straw into high-value chemicals and H2 energy is significant for biomass resource utilization. A circular electrolysis system was built using proton exchange membrane electrolysis technology and polyoxometalate (POM) catalysts, achieving corn straw degradation and H2 production. The experimental results showed efficient utilization of corn straw, high degradation rate, and high Faraday efficiency for H2 production. This technique provides a potentially new pathway for H2 production and corn straw processing.

Summary: The study focused on fabricating PMA and Cs-PMA thin films via low-cost hydrothermal reaction and compared their optoelectronic and photoelectrochemical properties, with Cs-PMA showing higher efficiency. XPS analysis confirmed the p-type semiconducting nature of Cs3PMo12O40 films, and the enhanced conversion efficiency of Cs-PMA was attributed to its optimal band gap energy and improved crystallinity.

Summary: Conversion of renewable lignin into bio-aromatic chemicals is a sustainable pathway to increase biorefinery profitability. In this study, micellar molybdovanadophosphoric polyoxometalate catalysts were prepared and applied for the depolymerization of birch lignin. These catalysts showed efficient cleavage of C-O/C-C bonds in lignin, yielding high lignin oil and monomer yields. The catalysts also demonstrated excellent recyclability and stability. The application of amphiphilic polyoxometalate catalysts facilitates the valorization of lignin, offering a potential strategy for harvesting aromatic compounds.

Summary: With rapid industrial development, a large amount of industrial wastewater is produced, containing highly toxic and carcinogenic compounds. The existing treatment processes have limitations in removing refractory organics and nitrogen. Therefore, the integration of adsorption and catalytic biodegradation over bio-carriers has been developed as a promising approach.

Summary: In this study, an In(I) doping strategy was used to enhance the photocatalytic performance of BiOCl by promoting the loading of OVs. This was achieved by reducing a sluggish In(III) precursor with UV light. The In(I) site was found to be an important electron transfer site that directly reduced the target pollutant, resulting in improved degradation efficiency. The study also revealed the selectivity of In(I)-doped BiOCl for different aromatic organic compounds, with the highest degradation rate observed for the compound with the lowest negative charge density on the benzene ring.

Summary: In this study, Fe(II), Zn(II), hydroxylammonium, and hydrazinium pentazolates were prepared and their thermal behavior, decomposition kinetics, and thermodynamic activation parameters were investigated. The results showed that metal salts exhibited higher thermal safety than non-metal salts under the same conditions, and Fe(II) and Zn(II) ions promoted the decomposition of pentazolate anions. These findings suggest that the prepared compounds have great potential as energetic catalysts for solid propellant decomposition.
