近年来,原位光催化可持续过氧化氢合成技术受到越来越多的关注。其中石墨氮化碳(g-C_(3)N_(4))被认为是最有前途的合成过氧化氢的光催化剂之一;并且,在g-C_(3)N_(4)中引入氮空位已被证明是提高其光催化活性的有效策略。然而,由于g-C_(3)N_(4)中不同类型的氮空位对光催化活性的影响方式不同,氮空位的光催化作用机制尚不清楚。在此,本文提出了一种简便的过硫酸钠共晶聚合方法,制备了具有丰富三配位氮空位(N3C)的g-C_(3)N_(4)。这种类型的氮空位在g-C_(3)N_(4)光催化产过氧化氢的研究中尚未得到重视。本研究的结果表明,在g-C_(3)N_(4)中引入N3C空位可以成功地拓宽光吸收范围,抑制光激发电荷的重组,增强O2的吸附和活化。富含N3C空位的g-C_(3)N_(4)的光催化过氧化氢产量是原始g-C_(3)N_(4)的4.5倍。本研究提出了在g-C_(3)N_(4)中引入N3C空位的新策略,为开发光催化产过氧化氢的活性催化剂提供了一种新方法。

Lake eutrophication caused by nitrogen and phosphorus has led to frequent harmful algal blooms (HABs), especially under the unknown challenges of climate change, which have seriously damaged human life and property. In this study, a Bayesian Network (BN)-SWAT+ model framework was constructed to elucidate the mechanisms between non-point source nitrogen pollution in agricultural lake watersheds and algal activities. A typical agricultural shallow lake basin, the Taihu Basin (TB), China, was chosen in this study, aiming to investigate the effectiveness of best management practices (BMPs) in controlling HABs risks in TB. By modeling total nitrogen concentration of Taihu Lake from 2007-2022 with four BMPs (filter strips, grassed waterway, fertilizer application reduction and no-till agriculture), the results indicated that fertilizer application reduction proved to be the most effective BMP with 0.107 of Harmful Algal Blooms Probability Reduction (HABs-PR) when reducing 40% of fertilizer, followed by filter strips with 0.01 of HABs-PR when 4815ha of filter strips were conducted, while grassed waterway and no-till agriculture showed no significant effect on preventing HABs. Furthermore, the combined practice between 40% fertilizer application reduction and 4815ha filter strips construction showed synergistic effects with HABs-PR increasing to 0.140. Precipitation and temperature data were distorted to model scenarios of extreme events. As a result, the combined approach outperformed any single BMP in terms of robustness under extreme climates. This research provides a watershed-level perspective on HABs risks mitigation and highlights the strategies to address HABs under the influence of climate change. © 2024, The Authors.

Numerous regions across China have introduced "dual carbon" policies, yet the response of cities to these policies remains unclear. In this study, we used emission data from 271 Chinese cities for the years 2010, 2015, and 2020 to construct a complex network of urban emissions with a modified gravity model. By modeling the strategic interaction behavior of unban-level response to the policy, we simulated the diffusion process of the "dual carbon" policy among cities through network evolution analysis. It was found that China's carbon emission network primarily comprises four urban agglomerations: Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta, and Sichuan-Chongqing. The "dual carbon" policy exhibits a network diffusion effect, with cost-effectiveness serve as a critical factor influencing its spread. And the current low carbon price in China does not provide adequate positive incentives for carbon reduction. Additionally, through counterfactual scenario analysis and an exploration of network structural characteristics, we highlighted the vital role of core cities within urban agglomerations in facilitating efficient policy diffusion. This study offers valuable insights for the selection of pilot cities and the sustainable regional dissemination of policies, providing guidance for more effective policy implementation. © 2024, The Authors.

In recent years, Fenhe River Basin (FRB) wetlands have been facing severe challenges due to climate change and human activities. It was of great significance to understand the dynamic changes of FRB wetlands and their driving factors for ecological protection. Based on the land use data, runoff, rainfall and GDP data of FRB from 1980 to 2020, the evolution characteristics and driving factors of wetland pattern in FRB were analyzed. The results showed that the wetland types in FRB mainly included paddy, reservoir, river, beach and marsh. Among them, natural wetlands accounted for 72.46 %, and constructed wetlands accounted for 27.53 %. The main types of wetlands in FRB were river, reservoirs and beach, which account for 92.26 % of the whole wetland area. However, the dominant position of reservoir patch was more obvious than the others during 1980–2020. Landscape index showed that the shape of landscape tended to be regular and became more fragmentation. The transfer between wetlands and other land use types mainly occurred in the northern and southern parts of the FRB, and the main conversion types were occurred between dry land and wetlands, grassland and wetlands. Both natural and human factors drove the evolution pattern of wetlands, but the emphases were different. Runoff had a significant effect on wetland pattern at landscape level, while rainfall had a more significant effect on wetland evolution at class level. Urbanization rate and GDP had important effects on the evolution of wetland pattern at both class and landscape levels. © 2024 The Authors
