Summary: An E-fenton oxidation system based on Co-N co-doped carbon nanotubes (Co-N-CNTs) was developed, which exhibited fast degradation efficiency and reusability for the degradation of rhodamine B (RhB). The Co-N-CNTs were successfully prepared with diameters ranging from 40 to 400 nm. The system showed a high yield of H2O2 and the optimal conditions for H2O2 production were determined. The Co-N-CNTs/E-Fenton system efficiently removed RhB, with center dot OH playing a major role in the degradation process.

Summary: This paper reports the successful preparation of efficient CdZnS/SnS2/SnO2 heterojunction by sequential template approach and hydrothermal method. The heterostructure greatly enhances the photocatalytic degradation ability of Rhodamine B (RhB). The CdZnS/SnS2/SnO2 exhibits good stability and reusability, and its superior removal activity is mainly attributed to the formation of heterojunction improved light harvesting and enhanced separation efficiency.

Summary: In this study, a micro-nano dendritic zero-valent copper catalyst (mnZVC) was constructed by simple electro-chemical reduction, and its performance, mechanism, and degradation pathway for metronidazole degradation were investigated. The mnZVC/air system exhibited a significantly higher removal efficiency (92.39% in 120 minutes at pH 3) compared to commercial micron zero-valent copper. The versatility of mnZVC in degrading various pollutants was also demonstrated. The continuous generation of H2O2, due to the micro-sized dispersibility and nano-sized activity of mnZVC, was identified as the main reason for the high degradation efficiency.

Summary: In this study, hydroxylamine (HA) was used to enhance the degradation capacity of Cu2+/PMS process for refractory pollutants in industrial wastewater. Compared to Cu2+/PMS process, HA/Cu2+/PMS process effectively facilitated the reduction of Cu2+ to Cu+, leading to improved decomposition rate of PMS by 29.2% and removal rate of RhB by 77.6%. The study also investigated the effects of various factors on RhB degradation and demonstrated the effectiveness of the HA/Cu2+/PMS process in simulated wastewater.

Summary: ZnO/g-C3N4 composite photocatalyst is prepared by ultrasonic dispersion method for Rhodamine B (RhB) degradation from wastewater. The ZnO/g-C3N4 showed enhanced photocatalytic activity due to the heterojunction between ZnO and g-C3N4, which promoted the effective separation of photogenerated carriers. The photocatalytic degradation mechanism of RhB conformed to the S-scheme mechanism combined with DFT calculation.

Summary: Fe2+/H2O2-based photo-Fenton process is commonly used for pollution removal. However, the low activity of Fe species at neutral conditions hinders their practical applications. This study proposes the activation of in situ generated H2O2 for Fenton-like degradation of pollutants through catalysts without Fe species. A strip-like benzene and K+ co-doped g-C3N4 (KBCN) was constructed and demonstrated to have increased charge separation and enhanced H2O2 production, enabling the degradation of Rhodamine B (RhB) and Congo red (CR).

Summary: Surface Fe2+ content is crucial for the a-Fe(2)O(3 )Photo-assisted Fenton catalytic activity. In this study, a-Fe2O3 catalysts with three different morphologies were synthesized and showed different Photo-assisted Fenton-like activities for Rhodamine B degradation. Interestingly, the leaf-like a-Fe2O3 catalyst exhibited the highest catalytic degradation activity. The morphology of a-Fe2O3 was found to affect the surface Fe2+ content and play a role in the Fe2+/Fe3+ cycle in a Photo-assisted Fenton-like system.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
