Bio-capped and green synthesis of ZnO/g-C_(3)N_(4) nanocomposites and its improved antibiotic and photocatalytic activities: An exceptional approach towards environmental remediation

In this research study, we have synthesized the bio-capped ZnO/g-C_(3)N_(4) nanocomposites by employing lemon juice(Citrus limon) as a stabilizer and mediator. Fruitfully, lemon juice which contains various acidic functional groups and citric acid has the capability to block the surface of g-C_(3)N_(4) from chemical reactivity and activated the surface of g-C_(3)N_(4) for various reactions. Consequently, the agglomeration behavior and controlled shape of g-C_(3)N_(4) has also been achieved. Our experimental results i.e. XRD,TEM, HRTEM, PL, FS, XPS, and PEC have confirmed that the lemon juice mediated and green g-C_(3)N_(4)(L-CN) have good performances and remarkable visible light photocatalytic activities as compared to the chemically synthesized g-C_(3)N_(4)(CN). Furthermore, the small surface area and low charge separation of g-C_(3)N_(4) is upgraded by coupling with Zn O nanoparticles. It is proved that the coupling of Zn O worked as a facilitator and photoelectron modulator to enhance the charge separation of g-C_(3)N_(4). Compared to pristine lemon-mediated green g-C_(3)N_(4)(L-CN), the most active sample 5Zn O/L-CN showed ~ 5-fold improvement in activities for ciprofloxacin(CIP) and methylene blue(MB) degradation. More specifically,the mineralization process and degradation pathways, and the mineralization process of ciprofloxacin(CIP) and methylene blue(MB) are suggested. Finally, our present novel research work will provide new access to synthesize the eco-friendly and bio-caped green g-C_(3)N_(4)nanomaterials and their employment for pollutants degradation and environmental purification.

Synthesis and Characterization of β-Cyclodextrin Modified Biochar Environmental Remediation Materials

In this paper, biochar (BC) was used as raw material, activated by deionizing aqueous solution, NaCl solution, CA solution and HCl solution respectively. Epichlorohydrin (EPI) was used as crosslinking agent, and β-cyclodextrin (β-CD) was used to modify biochar (BC). The prepared modified biochar materials were labeled with β-CDBC, β-CDBC-Na, β-CDBC-CA and β-CDBC-H, respectively. The infrared spectrum, X-ray diffractometer, scanning electron microscope and specific surface area of the four modified materials were tested. The results showed that the C-O stretching vibration peak at 1020 cm−1 of the modified materials was slightly offset compared with that of biochar. The characteristic absorption peaks of XRD pattern decrease obviously at 2θ = 26.7˚ and 29.5˚. It can be obviously observed on the electron microscope image that the surface is loaded or formed clathrates, and BET data and graphs also show that the specific surface area of the modified biochar is larger. Therefore, β-cyclodextrin successfully modified biochar and formed clathrates on the surface of biochar or was loaded in the pore structure of biochar, especially β-CDBC-CA achieved better modification effect. Because biochar and β-cyclodextrin raw materials are cheap, easy to prepare and green, and less prone to secondary pollution, it has a good advantage in environmental governance.

Circulating Environmental Logistics Channel for Sustainable Society

This paper suggests the important role of trust as a governance mechanism for the circulating environmental logistics channel for reuse and recycle. Three types of the circulating logistics channels are discussed. The first is the recycle channel, where an actor (a firm) can govern total channel and its flow. In this channel, an actor bears the role of entrance and exit, and processes goods, resources, and waste. It may be called as the closed circulating logistics channel. The second is the recycle channel of kitchen garbage, which is governed by plural actors, such as firms, consumers, and governments, based on trust. This channel may be called as the open circulating logistics channel. The third is the recycle channel with intermediate traders and retailers. This channel may be called as the intermediate circulating logistics channel. It suggests to us that actors with autonomy and volunteerism can promote and make a successful circulating environmental logistic channel under the mutual trust and the cooperative role sharing.

Environmental Technical Standards and the Green Transition of China’s Manufacturing Industry

Distinct from the existing literature conforming to the Porter hypothesis which emphasizes the technological innovation mechanism,this paper examines the mechanism of technological transformation through which environmental technical standards influence the manufacturing industry in reducing emissions and improving efficiency(i.e.green transition).Furthermore,drawing upon enterprise samples from the databases of Chinese Industrial Enterprises and Chinese Industrial Pollution Sources from Major Monitored Enterprises,it empirically validates the results of the theoretical analysis.Overall,our research reveals that environmental technical standards can propel manufacturing enterprises to reduce pollution and increase productivity by following an incremental path of technological transformation,thereby achieving a green transition.Moreover,environmental technical standards indirectly promote green technology innovation in the upstream equipment manufacturing enterprises.Heterogeneity analysis further shows that environmental technical standards have a stronger effect of green transition on those companies with higher pollution emission intensity,lower productivity,slower capital renewal and stronger financing capacity prior to implementing the environmental policies.

Green technical innovation, environmental expenditure, and the environmental Kuznets curve:a dynamics model

The relationship between the emission of pollutant and economic growth has attracted a lot of attention in the environmental debate of the recent decades. Based on some theoretical and empirical research on environmental Kuznets curve （EKC）, this paper introduces the environmental technical innovation and environmental investment into Salow growth model to discuss the relationship between GDP per capital and the emission of pollutant By the dynamic simulation and parameters analysis, the results of the model indicate： （1） when ＂green＂ technical progress and environmental investment are fixed, the relationship between GDP per capital and the emission shows the linear relationship; （2） ＂green＂ technical progress can lead to the positive growth rates with a decreasing level of emission, which is compatible with an EKC; （3） the proportion of the environmental investment can lead the different growth rates and level of emission. These results can explain that developing countries are ＂too poor to be green＂.

Analysis on the causes of massive stranding of Yellow Sea green tide on Lianyungang and Rizhao coasts in 2022

In 2022,Yellow Sea green tide caused by Ulva prolifera reached a historic minimum and the coastal areas of Shandong Peninsula were less affected.However,the largest amount of seaweed biomass has been washed ashore on Lianyungang and Rizhao coasts since 2015.We studied the development pattern of Yellow Sea green tide in 2022,and analyzed the key environmental factors on the growth and drifting,then discussed the possible reasons that resulted in the massive stranding of green tide biomass in Lianyungang and Rizhao.Results show under the combined influence of the east to southeast winds and currents with shoreward anomalies,green tide drifted to the coastal waters between Shandong and Jiangsu provinces and the distribution areas located westward compared with previous years(2008–2021).Floating U.prolifera rafts from the coastal waters of Binhai and Sheyang drifted continuously into the coastal waters of Lianyungang and Rizhao,providing important supplements for Yellow Sea green tide.Because green tide in 2022 distributed close to the coastal waters,the abundant nutrients might support their continuous high growth rate.In addition,the amount of rainfall around Shandong Peninsula from late June to early July were significantly higher than in previous years,which might promote the development of green tide to some extent.
