30. Construction of g/C3N4-ZnO composites with enhanced visible-light photocatalytic activity for degradation of amoxicillin.

Abstract

g/C3N4-ZnO composite catalysts were synthesized through surface hybridization of the delocalized conjugated-π structure of g/C3N4 with the closely contacted surface of ZnO via a successive and simultaneous calcination procedure, and two kinds of photocatalysts, g/C3N4-ZnO1 and g/C3N4-ZnO2, were obtained. Heterojunctions were formed between the two components, which promote the separation of photogenerated carriers efficiently, and then enhanced the degradation of 100 mg/L of AMX The degradation rate of g/C3N4-ZnO1 was 1.54, 11.33, and 2.52-fold that of g/C3N4-ZnO2, g/C3N4 and ZnO, respectively, at a 3.5-h reaction period, with the dosage of 0.3 g/L, and solution pH at 7.0±0.2. The recycle and reuse ability was excellent and 90.5% of AMX mitigation was achieved in the fifth cycle. For g/C3N4-ZnO1, electrons migrated from the conduction band of g/C3N4 to that of ZnO via the heterojunction. ·OH and h+ were the main active species for AMX degradation, compared to ·O2− dominated for g/C3N4. Twelve intermediate products were identified, and two degradation pathways were inferred for g/C3N4-ZnO1 and g/C3N4-ZnO2, respectively. Finally, transformation products without lactam rings were achieved, which lost most of the antibacterial potencies, and the ecotoxicity was also dramatically decreased as indicated by the ECOSAR program.

Abstract

In this paper, a zero-sum game Nash equilibrium computation problem with event-triggered communication is investigated under an undirected weight-balanced multi-agent network. A novel distributed event-triggered projection subgradient algorithm is developed to reduce the communication burden within the subnetworks. In the proposed algorithm, when the difference between the current state of the agent and the state of the last trigger time exceeds a given threshold, the agent will be triggered to communicate with its neighbours. Moreover, we prove that all agents converge to Nash equilibrium by the proposed algorithm. Finally, two simulation examples verify that our algorithm not only reduces the communication burden but also ensures that the convergence speed and accuracy are close to that of the time-triggered method under the appropriate threshold.

Abstract

Summary: In this paper, we study the resource allocation problem of second‐order multiagent systems with exogenous disturbances, and the communication networks are weight‐balanced digraphs. Different from the well‐studied resource allocation problems, our problem involves the disturbed second‐order dynamics of agents. In order to achieve the optimal allocation, we propose a distributed algorithm based on gradient descent and internal model approach. Furthermore, we analyze the convergence of the algorithm by constructing a suitable Lyapunov function. Moreover, we prove that the agents in the network can achieve the exact optimal allocation even in the presence of external disturbances. Finally, we provide two examples to illustrate our result.
